- Here I explain what 'that bit of string' does - AKA the VG system. I show the system and how it works, together with practical examples of using it in flight.
Let me know if you find this interesting and would like to see further explanatory type videos - and if you have any questions you would like to see answered on a video.
A perfect instruction, handling the theme with proficiency. The HG industry would thank you!
I've been watching hundreds of hang gliding videos for the last several years and I knew that the string did something to alter the geometry of the wing, but I"ve always wanted to see exactly HOW. Thank you so much for showing us the workings of the system!! I once saw a will's wing that had a lever on the bar that served the same purpose to tighten the crossbar. I was told (by Will's Wing staff) that it was affectionately known as the "chicken choker" lever because it could effectively decapitate a chicken by design. I laughed about that one for a bit!! Thank you again for the very valuable insight into that important aspect of the wing. I call the string and it's associated holding mechanism "the venetian blind" string because it operates just like the pull string on a venetian blind.
Wow that's interesting - I never heard of the chicken choker before! It brings several images to mind. Venetian Blind - that's a good one too - especially as it used to be called the VB cord.
Yea I have been started flying nearly 30 years ago, I already know all that. But I watched from start to finish, and I'm glad I did. Thanks for a great video.
You're welcome!! And thank you for watching!!
Thank you for the explanation! Helped me to visualize the VG on your transparent wing!
Great video, i especially like the explanations combined with the shots from inside the wing where you can see what is actually going on.
Thanks for all your videos, keep them coming!
Please make one of meteorology applied to HG
I'll add that to my list of videos to make - good idea, thank you.
Ah! I was wondering what that string was! I'm going to take a week off from work next week to learn to hang glide! It's a dream come true!
That's fantastic!!!! I hope it goes well for you - where are you learning? Please update me as to how you get on. If possible post some video of it!
@@MooSurfer Thank you!! I'm going to Lookout Mountain Flight Park near Chattanooga, TN in the US.
@@yoshidragonaga Excellent! I've heard it's really good there. I wish you every luck in your training and would love to hear (and see in a video) how you get on.
@@MooSurfer I'm wrapping up my week of training here and I cleared my hang 1 requirements! :D I only got one video, because I was so focused on learning and flying, but I uploaded it if you want to check out a little nobody :)
Thanks for that explanation. I'm new to HG and only just asked my friend was VG was. Then I found your video. Perfect.
I've gone from knowing absolutely nada about VG to being a couch expert! Thanks @Darren, awesome video and extremely useful as I break into my EP training soon. Best, Francis
Thanks Francis - sorry for the late reply - I hope you're doing well on your EP training.
Thank you Darren, great short class!
Clever stuff!, It's amazing how much effect the VG system has on the flying characteristics of the wing.
Yeah - and you can definitely feel the difference when you're flying.
The best explanation of VG I've seen yet. Thanks.
You're welcome! Glad you liked it.
Thanks Darren. Great explaination as I did not know how the VG worked. Would be great if you could continue with the explanatory videos as learning is what its all about.
Thanks Ian - I will try to - is there anything you have in mind that you would like explained?
What a beautiful Hang Glider, thanks for sharing this information...
Thanks for the video, I always dream about flying one of this since a little boy, I'm 57 now,, I'm not loosing my hope, to one day to fly
57 isn't too old to learn Armando! Get on a training course - you won't regret it!!
U can learn it even if u 60.. you need to be able to run a bit.. that's all..
Nice explanation Darren. Its always good to understand what many others may just take for granted. You won my subscription.
Thanks Jon - glad you liked it! Hopefully I'll have a lot more vids and detail like this, this year once UK covid restrictions lift. I'm planning a lot more flying...
Excellent demo !
I appreciate your open friendly nature; not something found among California hg pilots. I was surprised that while earning my private pilots license that pilots were actually friendly, not prevalent among the arrogant hg pilots here. Keep up the fun videos. Thanks Darren!
Thanks Scott - I've never been to California, but I can't imagine they're all that bad - maybe you just met the wrong ones! Or maybe they need a dose of Yorkshire charm ;-) More videos coming soon...
It was the sailplane pilots down on HG pilots when I was learning to fly sailplanes.(I know they are just scared. Chickens dont do alot of flying)
all the HG clubs and sites ive visited here in CA have been very friendly and helpful, sorry to hear you had a bad experience
Awesome video, good visual reference. Explained it perfectly, thank you.
Great, thanks Darren keep the vids coming
Thanks Darren!
Great video. My glider doesn't have a VG but someday!!!! All the best keep the videos going!!
Great video.
Well explained! great video. Thanks for share mate!
Glad I watched this as I too was wondering what the piece of rope was that you kept pulling.
I just pull it for fun really ;-)
@@MooSurfer 😂 looks good though 👍
Great info -- thanks -- I am considering learning HG!
I would heartily recommend it Bryan - it will be the best thing you ever do!
Great explanation
What keeps the hang strap from coming loose from the rocker in a negative G situation? I think I would like to see a strap around both sides that keeps them from being able to pop off the ends of the rocker. Is it just the pulling pressure that keeps the strap tightened around the rocker? Odds are they would never come off, and not knowing what secures them, I have concerns about that setup. I see the need for it to keep the hang strap away from the VG rigging of course, but something holding them from popping off would make me feel better. Absolutely LOVE your videos. Each and every one of them Darren. You are awesome and I love your lifestyle. Having only 25 flights on aerotow and 1 thermal under my wings, I have tons of newbie questions of course. Keep them coming and stay safe my feathered friend.
Hi Garry - thanks for the feedback and I am SO glad you enjoy the videos! There is a cable tie on each side that prevents the strap coming off the rocker. Also there is a backup system that goes around the keel, so if the rocker part fails you are still attached and able to fly the glider. I'll try to do another video that shows it. Glad to hear you're starting your hanggliding journey too - nice one! You'll be regularly thermalling away from the LZ in no time I'm sure - just keep at it! Any further questions you would like addressing on a video just let me know...
Darren that is such an amazing looking glider...what is the expected life span of the sail material? Thanks!
I don't actually know with this one... the previous sail lasted me 5 years. It's still in good condition and going strong, but I replaced it with the current black sail in order to effectively upgrade the glider to a new one. I've had this sail for over 12 months now and it isn't showing much in terms of wear. When I bought this sail I did go for one of slightly lighter construction in the undersurface, for ease of handling, in the knowledge it is likely not to last quite as long as the other one. I hope to keep it for 5 years like the other one but suspect it will last longer.
@@MooSurfer thanks for taking the time Darren enjoy your flights!!
Great video! Thank you!
for me, more questions than answers here. It pushes the wings “out” how? Out where? Alters the geometry how? Something about flattening the wings? How does that improve glide performance? I would have thought a flatter chord would mean less lift? How does it affect the speed of the glider? Improves the glide performance how? The rocker provides more leverage how? What does it actuate?
Good questions, sorry the video didn't explain well enough. Also sorry for my delayed reply - I've been off editing a while, but now returning. 1. Through the centre of the wing is a crossbar, with is in two parts with a junction in the middle. it is in a triangle, with the point towards the front of the wing. Each end of the crossbar is fixed to the leading edges of the wing. When I pull the VG cord, it pulls the centre of the junction backwards - making the triangle less of an angle and thereby pushing the leading edges out at the edges. This tightens the whole sail. The effect is that it becomes more difficult to turn (because turning is created by the sail deforming when weight is shifted, and the tighter the sail the less it can deform) but a better glide angle because the wing is now more efficient. Pulling the VG causes the speed of the glider to increase. I hope that gives some insight - I'm not an aerodynamic expert so some of my explanations might not be technical enough. Maybe I'll do another one of these videos and recruit a technical expert to explain better....
Only the coolest fly the finest..t2c is so stunning
Nobody ever accused me of being cool before...
wonderful

Hello Darren thank you very much for the explanation about the VG system in your hangglider.
I would be interested to know what typ of hangglider you would recommend to a beginner.
Hi, I'm glad you liked it! For a beginner you will fly a lower performance machine. But if you do learn, your instructor will recommend exactly which glider will best suit you with your weight and ability. It's best to get their advice - it will also depend on where in the world you are and what is available there!
Not all hang-gliders have a VG cord... note taken !
Hello Darren ,
Yoa are a happy bugger there under the T2C sail..
I have found your videos very interesting ! Very informative , exciting , gives me the sense of beeing up there again ..made a basic training HG-course when I was working in Norway Kongsberg in the mid 80ties!
However did not afford to buy a wing at the time and then came family life in ..
I have some question regarding having a tail wing mounted ..whats is your opinion for that as an .. horisontal or vertical or mixed ? ..second Q is I have noticed some pilots using a parachute as they land ...Gerolf among others ..is this the main rescue parachute or is it a special brake parachute ..whats your opinion about this approach
at LZ ? Have you tried it ?
Hi Anders, I'm sorry for my late reply - I missed your comment. I have never flown with a tail wing because the gliders I fly have the correct stability without needing one. The tail wing is part of the glider design specific to the glider and not an optional extra. So if it was designed with one, then I would use it. If not, then no it's not required. The parachute you see is called a drogue chute. It is designed to bring the pilot down faster so is useful for landing in an area where there are small landing fields and light winds. It does not slow the stall speed and does not remove the need for the pilot to flare, in fact it makes the 'flare window' slightly smaller. But when they pull on speed with the drogue chute deployed, they definitely come down faster. No - I haven't tried one but I intend to.
And yes - I AM a happy bugger!!! Thank you :-)
Thanks for the detailed information , I do wonder how your legs are folded inside that bag? isn't it uncomfortable ?
Not at all - the harness fits my full body length inside it with my legs outstretched. If you look at just after the landing on this video czcams.com/video/dCADnR958ps/video.html you will see how long the harness is and how I can just slip my legs into it and then I zip it up in flight. It's very comfortable.
Hello Darren.. Am an old hang glider pilot haven't flown in 25 years.. Was hoping to ask about competition pilots and the changes you and maybe Chitty make to glider tuning and why. I have never quizzed any of the boys on what they do? do you rotate tips to take out some washout or limit it to batten profile changes.Hoping you can find it in your heart to give away some trade secrets Wink Wink..
Hello Blurtmenow, there are a number of changes that some pilots make. Many fly using 'racing wires' - these wires are much thinner than the standard wires and I'm told it DOES make a difference to glide performance. Also some people use a hang strap that connects direct from the harness to the hang point without a carabiner - again to reduce drag. As you say, some people do change their batten profiles and also rotate the tips downwards to increase glide efficiency. This is personal preference though and is a balance between glide performance and handling. Some pilots also fly with weight in their harnesses - for example Grant Crossingham, UK no. 1 flies with a harness that is likely to put your back out if you try to lift it! This is dependant on your wing loading though and again your preference in flying style. The other thing is sprogs. Pilots tend to lower them as much as possible in order to increase that glide efficiency. There is a danger here if you lower them below factory settings as you are taking them out of certification.
Most high performance hanggliders nowadays don't have a massive difference in terms of glide performance, it's handling that is making a difference - the race being won or lost in climb efficiency. I understand that the latest WW T3 is focussed on just this, with rotating tips to improve handling.
Personally I believe that pilot skill is the biggest factor and I'm not at a high enough level to gain much by making tweaks. I fly with my glider more or less at factory settings. I have racing wires, a standard carabiner and have not made any alterations to the batten profile. My tips are either on the bottom or middle setting (I can't remember which) but basically are set so I am comfortable with the glider handling. I have lowered my sprogs to the lowest recommended factory settings. WW provide 2 settings - the standard setting and the 'lowest recommended'. I would not change the batten profile or lower the sprogs further as I believe this keeps my glider within certification and keeps me safe - bearing in mind competition pilots are more likely to fly in challenging conditions.
Ollie may well make other changes to his glider, I'm not sure. To be fair, he's more clued up to it than I am!
I hope that helps - I realise you probably know most of that (and likely more than I know) but others reading this might not.
Anyway... being after the trade secrets does that mean you're going to make a come back? I think you should!!
@@MooSurfer I would love to do some more thermaling it was very cool..I'm afraid i wasnt that good back then' i had a few successes though.Have never entered a comp but flew wind dummy several times in Queensland at Eungella. The guns at that time where Drew Cooper and Thomas Suchaneck flying moyes xs gliders. I would have another crack but have to shed kilos and would still probably have to get a vintage xs 169 haha. Wills wing and moyes need to make fat guy gliders other than single surface.
Hey Darren. So with the crossbars being relatively in a 'fixed' position ( not being able to move 90 degrees in relation to the keel -as in 'floating 'crossbars) - does that mean the sail tension
( and sail cloth construction )as the sail progresses to the tips is 'softer' than at mid chord
( not counting sail billow when VG is off)? I have noticed with aging comp gliders the sails at these points seem to be more 'shagged out' compared to the rest of the sail( speed alone can not account for this happening { +UV?}).The Flight Sails Shark(early 80's) was great in a straight line but sucked at turning - I often wondered if it had to do with the Sail stiffness.
If you're wondering-I'm a returning Hangie that works as an Aircraft Engineer.
The modern materials are science fiction considering the stuff we used to leap off hills with 37 years ago when I started. Although the hills have seemed to have got a tadge bit steeper than I remember them to be...LOL !
In actual fact Jutte, the hills have become less steep and actually smaller, due to the erosion effect from countless hang-glider & paraglider pilots running down them! ;-)
In response to your sail question my answer is... ERM...!
I'm not an expert on construction so take my answer with a pinch of salt, but no, I don't think the sail cloth construction is softer at any point, but is made of the same stuff throughout. The trailing edges of the sail do have less tension than through the centre line and there are sometimes issues with them 'flapping' when flying fast. Wills Wing have countered this with little carbon fibre sticks that you insert into the rear of the sail to give it more stability. I think in the T3 they have also used a more durable and thicker material along the trailing edge. Does this answer your question or have I missed the point? To be fair, you're probable better qualified than I am to answer it!! ;-)
Jutte 777, the keel is still floating relative to the crossbar. There is no big keel pocket, but if you notice, the rear lower wires are converging at some distance under the keel tube and then there is a single wire going to the keel. That allows the keel to move left and right a bit. If you have had a chance to see some videos in flight from behind, you can clearly see the movement and the change in a billow of the left and right wing.
Really enjoyed the explanation. On a different topic, does the hang point strap have a set life or do pilots change them yearly?
Thanks David - we don't change the hang strap annually, but checking the hang strap should be part of a pilot's regular checks. If they appear damaged or frayed then we should not fly and instead change the hang strap. My current one has been going a few years and is still going strong.
Отлично.класс👍👍👍👍👍
Спасибо!
Great video Darren! I've always wanted to see what the VG mechanism looked like and how it worked. You mentioned that the control bar (base bar) moves backwards when you pull the VG on. How does the VG system do that? Is it because the VG system moves the wing tips forward moving the glider's weight forward which makes the nose pitch down (reduces the angle of attack) which has the effect of moving the base bar backwards?
Thanks David! Yes your explanation sounds feasible. The effect is different with different types of gliders too.
David - you are partly right. The other reason is that by flattening the sail, washout is reduced so that more lift is generated at the wing tips. This means that for any given weight, less lift needs to be generated by the centre of the wing, so it can fly at a lower angle of attack, which in turn means less drag. This accounts for why Darren said that the stall speed is lower - because more of the wing is flying efficiently. This also means that when the wing stalls, more of it stalls quickly which is why Darren said that the stall with full VG is more severe, and will happen more suddenly. The wing tips are behind the centre of gravity, so when they generate extra lift the wing will be flying slightly flatter. With full VG, the centre of pressure (or centre of lift) will be further back. All these effects lead to the base bar being further back at trim speed when full VG is applied. HTH.
@@RogerM9 Thanks!
Do the fast, sport wings have a longer glide ratio than the big wings like wow alpha and falcon 4?
Hi Walter, I don't have the details of their glide ratio, but common sense would tell me that yes - these fast sport wings will definitely have better glide ratios than those beginner gliders. The exact details of the glide ratios should be on the Wills Wing website I think.
how do you loosen the VG back to its original form since i see only one string.
Or my question is are there more than 1 VG sting to tighten and loosen it?
Good question - no there is only one string. It's under tension, so releasing it just naturally let's it come off.
What is the difference in glide ratio between full vg setting and of
I don't know the figures behind the glide ratio. But it does make a noticeable difference when you're on a long glide. Also with the vg setting full on, it's much easier to go faster as it makes the bar come back - a bit like setting trim in an aeroplane.
Hi...thanks for these good videos....I wonder is it safe enough for anyone to learn flying the hang glider
many thanks
Yes - provided you have the correct instruction and you are at least reasonably fit.
does flattening the wing with the vg increase the risk of tumble?
It does - as does flying fast through tough air. Though it's a very unusual circumstance. But I'm flying in really rough air I always slow down and let the VG off a bit
Always a cost benefit. Thks
How long have you been hang gliding ? When did you change from a low performance glider to a high performance? Also what is the ball park cost of a T2C?
I have been hang-gliding for 20 years, though did have a 6 year break and have only flow in competitions for the last 8 years. I changed to high performance when someone broke my hang-glider by losing it off the top of their car - the high performance one (an Aeros Stealth) was the only one available with my local dealer at the time! I had been flying about a year at the time I think. A T2C - I think around 10,000 pounds if you have all the extras. Although I think they don't make T2C now - they recently moved to T3. Similar price but better handling.
Very good thanks. Flex wings appear simple but there’s a lot of design in them. I see there’s no “back-up” hang strap. Has there ever been a failure of one ? I ask because apparently there has never been a know failure of the hang bolt on microlight trikes. Is it one of those things that’s so over specified for its task that the glider would fold before the hang strap ever reached its limits.
Hi Thpxs05, there actually IS a backup. I didn't explain it in the video (because I was focussing on VG) but there is another strap for backup which goes around the keel. So if the rocker or main hang strap fails then you are still attached and can fly the glider. I've never actually heard of a rocker or hang strap failing, although I have seen a rocker bent seriously over following some sort of accident (I'm not sure what the accident was, I only saw it afterwards - it was a non-injury accident though). That also damaged the keel and the glider had to be repaired.
I do think the rocker element of the glider is likely over engineered though, yes so it's unlikely to fail.
Sadly there was a case of a hangstrap failure here in Australia at one of our summer comps. It was an Austria pilot...whose name I have forgotten...who had made his own thinner hang-strap. Normally the strap is made of two layers of webbing lightly stitched together. One is the primary and goes to the 'dingle-dangle'....the other the backup which wraps around the keel. The pilot had made his hang-strap without the backup or used thinner than std. webbing. His glider tucked on a glide...possibly due to him gliding with a lot of VG and not enough reserve speed. The force on the hang-strap during the tuck broke it...and unfortunately by the time he was able to deploy his parachute its bridle broke too because HG parachutes are not designed for high speed deployment....rather they are deployed at slower speeds with the glider creating a lot of drag itself.
I saw it all happen and helped find him. It has haunted me for a decade now.
Do not cut corners with equipment. The big manufacturers know what they are doing now....not like the early days of hanggliding.
So take off and landing you would want minimum VG? Thanks.
I usually take off and land with about one 1/4 to 1/3 VG. This gives a bit more speed and roll authority on the T2C. Though in strong winds you might want a bit more. Depends on the glider too - I think a lot of people on other gliders DO take off and land with zero VG.
So the default is VG off, correct? You pull the string to activate VG, and let go and it goes back to no VG?
Yes - default if VG off with no string pulled. For my glider I usually take off and land with about 1/4 VG. It gives a little extra speed and authority.
Sir pls give good reply....or can u give the measurement of hanglider....
Hi, my glider is 154 ft square. It is a Wills Wing T2c - look on their website for more detail.
@@MooSurfer ...yes sir but no any other mechanical drawing in that websites....sad to hear.....😢
You are thinking of building one? Believe me you won't be able to unless you have a lot of specialist equipment and knowledge. If you want to fly a hang-glider... Get some lessons and your instructor will help you with a suitable wing
Very interesting, I always wondered about that. However, how to you "unpull" it? You can't just stuff it back right?
Good question! When the wing is loaded (ie. with me flying it) it naturally pulls the VG cord back in. So when I pull it on, I secure it in a cleat. Then to let it off again, just free it from the cleat and allow the cord to pull itself back in until I reach the new setting that I want, when I again secure it in the cleat. Not sure if that explains it well enough? Perhaps I'll need to do another video...
@@MooSurfer Just what I was wondering, thanks for the answer! Cheers
Please tell me how I made one with machine
I don't understand your question, sorry.
Hi Darren. I am currently learning hang gliding and am enjoying your videos - thank you
I think I understand from your video the cross bar straightens, pushing at its joins to the leading edge making the leading edge straighter, less swept. This would tighten the trailing edge I believe and maybe this is what you were saying when you said it made the sail stiffer. Am I correct this would increase the top side curve fore and aft generating more lift? Is it the case that the glider not only picks up speed but decreases its sink rate? Thanks, Matthew
Hi Matthew - glad to hear you're learning - trust me you'll never look back! Just put your all into it, this is the most difficult bit, once you've learned it gets gradually easier and you can fly more and more. Yes you're right in your description of what the VG does. And yes it generates more lift so you actually fly more efficiently. It also reduces the stall speed, despite the bar coming back and the wing speeding up. Though the stall becomes more pronounced with the VG on.
Thanks Darren. La Nina is making learning HG very tough on the east coast of Aus right now!
Does the tightened VG cord affect wingtip washout? I would hate to have a tip stall close to the ground!
Certainly when you have VG on you are likely to experience a more severe stall. Although it does actually lower the stall speed. As for wingtip washout - I don't know.
From my experience ending in 1982 when a gave up this amazing sport the Nose versus tip stall was considered easier to recover from if there is adequate remaining altitude. Sadly I and friends witnessed a horrific accident when a novice, showing off for his girlfriend tip stalled while attempting ridge soaring and I was first to be at the side of the downed flyer with no way to help. He survived but with severe brain damage. I lost several close friends including Willi Muller, had a midair collision etc. Before finally giving it all up as one shoulder would often partially dislocate on final landing approach. I also developed a nervous condition including brief periods of stuttering while trying to present the sport in public speaking.......To this day I miss this sport severely.
Graydon....loosening the VG increases the trailing edge billow out towards the tips. Darren doesn't mention it in the video but VG movement also effects the anhedral/dihedral of the wing. With VG off the wing effectively has more dihedral making it far more stable. You would never land with VG on more than about 1/3....unless smooth stronger winds. Also VG completely off is not optimum for most landings. About 1/4-1/3 on is normally best as it raises the angle of attack of the wing tip areas making for an easier flare at landing. VG fully off is mostly used for tight thermaling as it allows for more twist in the wing.
I been flying a U2-160 for last 8 years currently leave the vg permanently on 1/2 for t/o, landing, aero tow & coastal. This is not a good idea. ?!?
Hi Neville, firstly I would say - if it works and you've had no mishaps, then 8 years of flying with it on that setting then it clearly IS a good idea. I have read that having the VG on a higher setting for aerotow helps reduced yaw oscillation, so it sounds like you have a good setting for that. I've also read of other pilots who land it with the VG fully off. If you try this, remember the bar will be further out and have a tendency have less speed, so you may need to concentrate more on pulling speed on, to avoid a stall when coming through the wind gradient. I would suggest at least experimenting with more VG if you want to improve performance on a glide. Also you could try thermalling with less VG and see what it feels like in terms of giving you more control.
Here's what Wills Wing say in the manual:
VG full loose is for maximizing roll control authority and roll rate. Due to the slower trim and increased pitch pressures at VG full loose, you may find that total effective control is actually improved in some conditions at slightly tighter settings up to VG 1/4. VG settings between VG loose and VG 1/ 3 are recommended for working lift when any significant degree of turbulence is present, or when you are in proximity to terrain or other gliders.
Between VG full loose and VG one half, the glider retains good lateral control authority and response. Tighter than VG one half, the glider’s roll pressures increase significantly and the roll rate becomes significantly slower. Tighter VG settings are recommended for straight line gliding, or for flying in smoother conditions when well clear of both the terrain and of other gliders. The stall characteristics of the U2 at tighter VG settings are more abrupt and less forgiving and the glider is more susceptible to spinning. Full breaking stalls and accelerated stalls at tighter VG settings are not recommended.
Final point - if you've had it working fine for 8 years with no mishaps and don't want to change - then if it ain't broken, don't fix it!
Hey Darren I’m curious what you’ve got on your left index finger there
That's the PTT for my radio - it is a button that I press when I want to talk on the radio. It is linked to the radio via a lead that runs up inside my sleeve.
@@MooSurfer Very cool! After I wrote that I thought of course it’s a blood oximeter so there you go.
Hola Darren. I hope you are doing ok and thank you for your fantastic videos. How do I correct a turn when vg full using the sprogs? The glider turns to the RIGHT when I apply vg
Hola Jorge! I'm great thank you, glad you like the videos. Firstly - check your glider manual, there should be instructions there. Also check the batten profiles, the batten tensions and the overall symmetry of the wing. If it is a sprog issue and the glider is turning to the right, that suggests to me the sprogs on the right hand side may be set too high, or the left hand side set too low. Check the sprogs on both sides for the angle they are set at (do you know how to do this?), and check they are within the manual specification. It may be obvious from the measurements which sprog is causing the problem. Whatever you do, do not lower sprogs to a lower angle than is recommended in the manual - that is dangerous. I hope this helps? What glider do you fly?
@@MooSurfer Gracias Darren! Battens are good both in tension and shape.... I guess I know how to check the sprog angle with my phone level tool but I am not sure how to level the wing in regards to the ground.....and there are no leveled surfaces arround here at all.....I fly a Wills Wing Sport 3 and there is no detailed info in the manual about sprog tunning unfortunately. Once again thank you
That combat was smoking you on glide.
Yeah - combats have a VERY good glide. I totally got smoked!
Sir, I speek from Bangladesh. I made a hung glider. But its going to over 20 KG weight. Can you tell how much weight shound hung glider?
My hang-glider weighs about 32 KG. But making your own is a very dangerous idea...
@@MooSurfer thank you sir, for your reply. If you any mail please let me know. I will give my glider picture and video to share you. I have already complete 80% of my glider working. Some time i fall down problem to making it. Beside i slove this problem by the others glider resources academy. So i wish my sir to help me to complete my glider. I will use a 5 or 6 horse power engine to gliding and adjust a mini vehicles to attached it. So i am new in here and dont idea better to make it. So if you help me i will be glad on you sir. Please give your email address. I will send my glider video and picture.
@@monirkhan-oq4ly sure - send me your video and picture. I definitely don't recommend you making your own glider, but if you are doing it anyway I'll give my comments on it and possibly show it to my friend who makes Hanggliders. My email is darrenbrown50@hotmail.com
