Finally I made this video! I do my best to explain F5J to people who have never heard of it before or who want to try it but don't really know what's going on.
RC Sailplane thermal flying contests!

Guys, I made a goof up on the rules regarding launching! You can launch your model anytime during the round. I.E. you can wait till 9 minutes have passed then launch. Obviously you will only get a .59 second flight time. There is no "30 second" launch window. You cannot launch before the buzzer.
Just like any race you have to wait for the buzzer but after that you can just sit on your ass as long as you want.
Thanks for the explanation, I finally now understand the competition format 👍
Thanks Ali. Very cool and clear description of the contest. After watching your filmed contests, I kind of guessed the rules and objectives, but this video gels it all together.
Thank you Araye!
Great and passionate description of F5J! Fun to watch.
Thank you
Great video! Thanks for the comprehensive explanation. I have flown a few F3J and F3K contest but never F5 and this explains it as I would ask it.
I’m looking into this class. One of the kinds of flying I’ve never done in my 20 years in the hobby. Once I did get an UMX ASK-21 in a thermal and it was a rush.
Thanks for clarifying this class, no more questions!
Congrats on getting the Ask-21 into a thermal. My longest flight has been about 3 seconds!
Thank you for this. Great explanations. Flew a 3m balsa model this summer, catching thermals. Really bitten. I'm expanding the hangar with some smaller powered sailplanes for now, maybe something fancy later on. Who knows, maybe I'll compete one day!
Very helpful video, I've been flying now for about 4 years, started with planes but I really love the gliders because I used to fly them when I lived much closer to the airport. I knew F3j were motorless and F5J had motors, but I've looked up the rules several times and had a vague idea, but never really knew. The video, makes me want to find a larger glider, my largest now is a Nan Orion that is a dream to fly, and I just completed a Armsoar Fury (F5K) and its fun, especially just to grab something quick and fly, I can throw it assembled in my car, but after flying my Orion for a while, really ready to get something in the 3.5 to 4.0 meter range, and I'll start looking for F5J contests. It was a very good and well done primer, thank you!
Thank you Will! Hope you try 5J!
I loved the vídeo!! Thanks for sharing your passion for F5J and how the competition works!!
Thanks
Thanks for the video. I found it interesting. I am looking to return to flying having had a 20 odd year break and I having flowing mostly power in the past, I am intrigued at trying something new. So was nice to watch. Cheers.
Thank you for clear overview.
That was very interesting, thanks!
I live a 12 hour drive from the closest contest so your videos are a great window in a part of the hobby that is not present where I live!
Glad to hear it! Happy flights!
Great Vid. You rambled a little bit, but there were points where your enthusiasm and passion for F5J could be totally seen. You really have a heart for this discipline. Keep up the good work, this hobby/sport needs more people like you.
Thank you sir!
@@flightcomp Your welcome Brother!
I enjoyed the video! Makes me want to give F5J a try! I've recently taken an interest in vintage gliders and I think it would be fun to build one to try out in F5J before getting into the fancy stuff! Seems pretty simple and not hard to get into!
Absolutely! I just flew a 25 year old model in a competition and did pretty well!
Good video- thank you. Just got a used 3.8 Xplorer 2 to play with- might enter a contest some day. One thing I can say- its a lot easier to see my 2M Gentle Lady down range in a thermal than the Xplorer! Disappears when edge-on! Can't see it at all!
So helpful. I really didn’t have any idea.
Thanks it was a great explanation!
This was great, thanks! I'd love to see a video about entry level models, components, etc.
Great video , Thanks 👍
👍🐨✈ well presented. watched your other videos. helped me to enter f5j..Keith Australia
Thank you Keith!
great video!
Great explanations. Very nice!!!
Glad you liked it!
@@flightcomp Hello Ali, I sent you an email. Arnaldo Medeiros - Brazil
Alright! Thank you.
Always been curious. Thanks for the explanation.
Thank you for the explanation. I have been watching similar f5j videos and it got me interested to a point where I started doing some research into makes and models within the class. I was flabbergasted at the price of these planes! You can buy a very nice second hand hang glider for the cost of a single f5j setup! It becomes a wallet competition where you pay for the carbon fibre feather-weight compared to a balsa model at dread-weight, just like when I flew hang gliding competitions. Maybe do a segment on entry level models and how to compete with these, obviously more of a challenge, but I’m sure like me a lot of potential enthusiasts are put off by the price.
Love your shirt brother 👍 so many of your viewers would have never heard of the radios that all the clones were actually copied from
Thank you !
Wow. That is way more interesting than I thought. Can you guys give an overview of other formats? I'd be cool to have some sort of commentator for vids of comps. Thank you. Someone finally made a rules vid.
ALES (Altitude Limited Electric Soaring) is the other (less) popular format in North America. All the altitude devices are set to a common cutoff altitude (100m, 150m or 200m) so everyone launches to the same height. 10 minute thermal endurance flight followed by a landing. ALES tends to be a landing contest more than a flying contest and is one of the main reasons it is less popular with experienced pilots. It is a great format for folks just getting into competition - there's none of the fear/uncertainty of launching super low as you do in F5J. I started in ALES and have moved on to F5J and my club here in Canada only runs F5J contests now.
Thanks for this very interesting, informative and well presented video. You started with a presentation of the models used for F5J and I’d like to ask you if there is any advantage to choose a V-tail versus a “traditional” X-tail. Thanks for your channel.
Not really, some say V tail is less drag and less parts so lighter. However V tails can be tricky to get flying well.
Nice video see you at Parris
Perris 🤣
Just a note , I am not sure that you mentioned on the launch height that the altis measures the highest point during the power phase +10 seconds , so ANY height in the 1st 40 seconds is recorded.
I didn't go into tons of details because I didn't want to overload people with information and make it super long and boring. I'm thinking later I will do a few shorter videos covering specific topics in more detail.
Does the min wing loading get checked before or after landing. I'm thinking ballast which you can dump
Very informative clip, specifically for person from India, who has only heard of these competitions but have had no real time on taking part or observing them.
One request, if you could make a similar clip on reading the air with general guidelines experts use .
Georje
I don't think I'm expert enough for that, however it has already been done.

@@flightcomp thanks Sir
F5J gliders are amazing just beautiful. I would never turn a beautiful moldie into a lawn dart, not on purpose anyway lol! But to each his own ✌🏼😎👍🏼
Haha... Not "I will see you on the next one"... You should say "you'll see me on the next one"... 😁
Thank you Very much for that informative video!! 🙂
Any limitations on receivers or telemetry? Specifically Spektrum’s AS3X, variometers, altimeters.
Yes, no telemetry except battery voltage is allowed.
What would you suggest for a first F5J sailplane?. I’ve been building and flying sport planes for 39 years. Thank you, Great vid.
Something used! Maybe 1-3 years old. A little beat up. Learn the format and tactics with it, then move on to a new model.
Do you have to be stopped by the time the buzzer goes off, or just on the ground.
Just on the ground.
Is the landing location the point of first contact or where it comes to rest? I'm assuming your timer performs the measurement?
Where it comes to rest, measured from the nose.
I'm confused on whose timer counts in the end. Is it your caller's timer, which may not start until 30 seconds after the start buzzer when you actually launch, or the official timer, which starts at the launch buzzer? Thanks for the video! I'd like to try f5j some day.
I’ll try with my poor English. You caller times from the moment the model leaves your hand. But be aware: every pilot has to be in the ground before 9:59 as at 10:00 the buzzer sounds again to inform that the working time of 10m has ended. So if you start late within the 30 seconds allowed you are sure not to complete the 9:59 potencial time. So when your caller times your late start you can ask him for how long you are in the air but he can’t tell you how long to landing. In case of a late start you should have some form of knowing the how long to the end of the working time of 10m. If you launch your model with the star of the working time buzzer than you only have one time to check during flight.
It’s normal to carry one crono and give it to the caller before flight and ask him the favor of keeping the two timers working, one at the beginning of the working time and the other at the time the model is launched.
@@epoxyexpert Thank you for the clarification. That helps. Your English is great!
I think Joao did a great job explaining.
I am confused about the start. I do not find anything in the rules that says that you have to launch within 30 seconds of the start of the working time. Only that your continuous motor on time is limited to 30 sec. If one delays the start of their motor, I don't see why they couldn't launch at any time during the working time if they wanted to delay as a tactic. Please cite the number of the rule if I am wrong. Thx, Wayne
Totally correct, messed up on this one. I plan to address some issues and things I overlooked in an upcoming video. Thanks!
I want to see somebody win flying a foam Radian
If you're gonna downvote leave a comment!
I’ve got one, that thing will find thermals on its own! Super fun to fly after a few stiffening mods, haven’t flown it in years because there’s not many places to fly it near me.
Thank you Ali!
That helped me a lot. I fly at a small club in lower nowhere. Nobody competes or, flies anything bigger than a Radian😝
Trying to find the Devil so, I can sell my soul for one of your planes!! Lol
haha......just get something used and beat up! You will save lots of cash!
Hey man....thanks for the great video. One quick question. If you could buy only one F5J model for under $3,000, which one would it be? Explorer? Thanks again, nice job!
I'd buy a used model. Any F5J model made in the last 5 years would be great.
I liked, but then saw it was 420 so just saying I like!
great video!
what about the other cat, do you fly them also?
I mostly fly f5j. I used to do f3j, but that's basically dead now.
@@flightcomp great channel👍
How much is a decent competitive model?
New? Starting around 1800 USD. Price goes up from there, a used model is a great way to go for a fist model. You will save a bunch of money.
"What is F5J?" -- class for people who can't find thermals... what ever happened to F3J
Hypothetical question - can you just not launch the plane until 9 minutes and 59 seconds and just "spike it" into the ground for a "perfect landing" score of 50 with zero launch height and zero flight time? Do you have to use all 30 seconds of the motor? If you're gonna downvote leave a comment!
Because all you will have is those 50 landing points. Everyone who flew for longer than you will beat you
I'm 4 minutes 19 seconds into the video and can't take my eyes off the glider to your right on the wall. It's gorgeous, what is it please?
Here is a video on it
czcams.com/play/PLK05zXmk7Awf_reE9R82x79Shkz99fgjn.html
👍
You say that it is sometimes good to launch low. What happens if you do this and don’t use the full 30 seconds of motor run time? Are you penalised for this?
Not penalized, you just have to thermal slightly longer.
Et cetera*
There is no "eck" hehe, just saying.
Interesting, but as a European I dropped out when you were referring to ounces and stuff. Go metric if you want to reach outside the US. 👍
This is great!...All I knew before about F5J guys... Bill Gates budget, PhD in transmitter programming, skill level +10,000 of me! :)
Still don't know why it's called f5j!
Just a classification system the FAI uses for model sport. F3A, F3B. F3J, etc...
OMG you talk without saying anything, even more than my wife 😂
no problem low
I would pay to see somebody win a major contest in a Radian. They embarrass big spenders at the little clubs all the time. 🤣🤣🤣
Електро F3J
Too much rambling about your videos at the beginning.
Thank you for the feed back.
Too verbose. Cut to the chase
