When soldering, I find if you put the iron underneath the joint and let the heat travel up it works much better.
From what i learned on youtube its also the correct way to solder wires, so that the solde wicks all the way through the wire.
The Iron is too cold/too weak/old wire/bad solder
Yeah the soldering did look dodgy
The placement of the iron tip has far less impact on the solder joint quality than the solder tip temperature. A higher wattage element, and/or larger tip would be the fix here.
@@meanderinoranges This is 100% true, the underneath trick only really applies with lower wattage irons. The majority of the heat transfer actually comes from tinning the tip of the iron so there is molten metal to bridge the gap between the iron and the thing you are soldering. Same logic as using thermal paste on a computer.
estes motors that are labeled D12-0 do not have a smoke delay (as indicated by the 0) or parachute ejection charge, but they do have an ignition charge to light the next engine on top of the D12-0 (as this is how they are intended to be used). This ignition charge is what ejected your motor.
yes, they make motors suffixed with P, which means they are plugged - no ejection charge
Correct!
You took the words right out of my mouth
the ignition charge is also just the end of the propellant grain
that makes a lot os sense as in the video you can see a small flash and the engine pops out the back with a smoke trail.
What I found ironic and fascinating was that as you worked on modifying the model's overall design, it started to turn into a German V1 Buzzbomb.
It reminds me of the Yokosuka MXY-7 Ohka especially, what with the H-Tail design and orange color
I love studying the vengeance weapons
What da hailll
Indeed
@@Eva-xj1wn Heil Hi-
Seeing Modelplanes fly always make me a little bit emotional because my grandfather always build these and flew them. Reminds me of simpler times
This is amazing dude! Also I can't tell you how loud I screamed when I saw the train going by in the background of your desk shot. So jealous of your office!
Glad you liked that man 😂 I’m lucky to have a pretty nice setup atm!
It’s nice seeing you here, you legend
Joe!! You rock(et) too!! Love watching your stuff!! Starting flying model rockets again with my boys because of you!!! Keep up the amazing content!! You are inspiring….
It’s not amazing in anyway. He strapped a commercial motor to a foam plane. And didn’t even break 400mph
Time stamp?
What if you mounted the camera in the rocket nacelle nose cone? It would bring your CG back, put the weight midline, and be simpler than cutting into the foam wing or foam nose.
I initally thought making a wingtip pod for it, then the idea of mounting it in the removable canopy came to mind.
The nose seems rather obvious else.
he better should get an insta360 GO2
How about trying it without the camera.
What camera are you using ?
I feel like I speak for most viewers from America when I say, we appreciate you doing conversions to MPH for us!
It's even more impressive since he has to convert from kilometers per hour to tea per hour to miles per hour. Have yet to see someone create a converter for tea per hour.
well yeah you guys use the worst kind of measurement system
we use kph in the uk as well, so it was probably more for us
yeah yeah ...but could you guys change your measurement system already?
@@jessicaguarin3897 countries that use metric that have been to the moon: 0

problem?
This was a dream of mine as a kid building model rockets and Rc planes with my grand dad! Those experiences drove my career choices, first into aviation as a jet engine technician, then into aerospace as a rocket engine technician. Loving this video!
Only suggestion I have that you may have ended up getting to, some cheaper model rockets use a metal tab that holds the engine into when the ejection charge fires. I’m not sure why your engines keep jettisoning, but a tan on the aft and vent on the front should prevent that and maintain stability.
What a great project, it makes me want to buy some of those motors and do some tests.
The camera is like a big aerobrake, if you remove it, you may gain 10 or 15 mph.
It would go faster, but it wouldn’t look nearly as cool to us
maybe he could incorporate a little cam in the head of the rocket motor slot?
@@ewan3607 the problem with that is the ejection charge used to eject the nose come of a model rocket produces quite a bit of force.
@@ewan3607 I think the camera housing should be replaced by a more streamlined form flush with the rocket tube. will give no adverse yaw when it will sit on centerline. Lenses are round, the camera itself is small, so integrating things will be easy and the rest of the electronics can be hidden in the fuselage.
he could put it in the nose with a aerodynamic cone on it and then he can see from the nose
Just a quick note. You're looking for motors ending in a P for plugged. 0 means there is no delay before the ejection charge. Great vid looking forward to the next one. 👍
Actually, it seems to me when it tosses that big heavy engine casing out the back it would give it a forward boost, so perhaps all he has to do is make sure that the bulkhead that the engine is mounted behind is nice and solid, and then the ejection charge would actually help him reach his goal of a speed record
@@brianward7550 "blasting the big heavy engine casting out the back" That's the ejection charge engines with a P at the end are designed to not do that. The bulkhead is built in and there is no explosive past the fuel. Thanks for the reply =)
@@wilgarcia1 12-0 engines have no ejection charge. It's a solid grain of BP and nothing else. No bentonite bulkhead capping it off as in the 'P' designated engines. These are used in booster stages. There is no ejection charge. The remaining burning propellant is what pushed the casing out.
I'd sleep much better at night if I knew there were more young people like you to trust our future to. Never stop being curious!
On behalf of everyone I say that this beauty deserve a pair of landing gear..
Your roll oscillation may also be "aeroservoelasticity," (ASE) also known as "flutter." Nearly all aircraft exhibit ASE at some high enough speed; it's usually a factor in the high speed limit given in the flight manual. The wing's natural flexibility (elasticity) can couple with the controls (servo) through aerodynamic loads, and result in oscillations that often result in failure of the structure. If you're getting the beginnings of ASE at 130MPH, you might get fully destructive oscillations at even slightly higher speeds. Typically the onset is rather sudden and even a few knots of airspeed mean the difference between some mild instability and runaway destruction. Yes, it could ALSO be simple gyro gain issues, but you should not fail to at least be aware of the possibility of ASE.
While a great technical explanation, what he was experiencing is gyro oscillation - easy to tune out if you reduce the gain by cranking down on a potentiometer in the gyro.
great explanation. thank you
What about installing the camera into the nose. That would negate part of your CG problems with the heavy rocket engines on the tail.
Love the projects so far and I’m more than excited to see the finished product of the V2 Jet Car because that design looks flawless and very aerodynamic, I know it’s capable of some amazing things. I just wanted to ask if you’ve thought about experimenting with VTOL on an aircraft. I don’t know what sort of benefit it would bring but I think it would be a nice thing to at least attempt.
This project is a reminder of the NF-104 of which Lockheed built 4 (I think) examples in 1963. They put the rocket motor in the vertical stabilizer with a significant downward thrust. Your project looked like a blast, thanks for posting
Even more crazy is that they put an F-86F with the same engine into Mach 1.22 before that.
Excellent project...two successful missions with rocket assist is very impressive. Can't wait to see the speed record get set!
@ProjectAir , instead of one big engine at the tail, how about putting 2 more of those big rocket engines 1 on each side of the wings near the aerolons and 2 small ones each side of the rear wing tips so it would be well-balanced. All should fire simultaneously for that added punch. As for the canera there are miniture lenses that can be mounted on the air intake portion by the body. Video can be recorded using microSD cards. I'll be waiting for this major improvement. More power to you!
The motors as you noted are a zero second delay before the ejection charge fires. These are used for butting up against another motor so it Gore's the second in staged rocket. Kick arse effort though, great fun!!
When you unboxed the jet, I thought "Nice, shame what's going to happen to it." But it survived! I do like an episode with a plot twist.
Keeps up the suspension for the next episode: Will he use a larger rocket motor? Will he compromise the structural integrity with the build in camera? Will the tuned gyro keep the plane in the air?
Nice job. If you are set on sticking with foam, I would definitely look at sanding the trailing edges and covering with a glass fiber cloth. A bit of work, but sometimes it's about reducing drag, rather than simply adding more power/thrust/weight etc
i always added the resin right on the foam istead of adding the cloth. the resin dries makes a hard shinny dull yellow on the foam. adds alot of weight. makes it firmer too
Been there done this. I centered the engine at the CG and made it eject when spent to launch gliders. You can also use a rubberband plane wound up, have a small metal pin stop the prop from unwinding. Then have a string tapped to the rocket engine and tied to the pin. You launch the plane with the rocket power, the rocket engine ejects pulling the pin and then the rubber band powered prop takes over. Had cometitions at the field to see who could get highest/farthest/duration from modded foamies.
I scratch built the Astro Blaster it was a set of plans utilizing Ace R/C foam wings and weighted balsawood and plywood 2channels for control, Estes model rocket engines without the parachute blast and vertical takeoff it was fun back then and I'm happy you find enjoyment from your rocket powered jet fighter. Keep the dream alive.
This is amazing. Love that whistle on the last rockets ignition. Super cool 😎
Nice video as always, but you should seriously consider getting someone to show you how to solder properly.
Great work man. Excited to see the improved version
P-80 to Unmanned Surveillance Drone, maybe you should add a camera facing down.
Nicely done, as to your rocket ejection, at the end the charge burns out of the front of the rocket ejecting it. You could glue an extra circle of wood on the top using epoxy to prevent that.
yes the airplane is great, but everytime i see your mini, my heart melts... sooo nice.
Model rockets tend to have an ejection charge after the main burn happens. The ejection charge isn’t for the rocket engine to pop out of the fuselage or tube of the rocket. The rocket engine is supposed to stay in the model rocket and the ejection charge is supposed to pop the nose cone off which then pulling out the parachute and shock cord
Anyways would be cool if you made a high power sugar rocket engine using sugar and stump remover it’s a little sketch but worth it
Did bro turn into markrober??
Maybe
Is it just me or is the sound of the rocket motor whooshing across the sky delightful?
You're using a Spektrum air receiver. They make those with gyro's built-in and that can be tuned directly from the transmitter. This would not only save weight from having to use a separate receiver and gyro but would also allow you to quickly tune the flight characters between test runs.
Make the entire wings batteries! Bet measured correctly they can house battery component materials thus removing extra space dedicated to only batteries.
I always dreamed of adding model rocket engines to my rc toys... I did it with a few cars but never tried to wire it in to the controller for wireless ignition.
I did, however, a few years ago add a pretty sick flame thrower to my Arrma Notorious 6S RC truck and that thing is amazing hahaha
This inspires me to get back into creating things.
I love watching videos like these! Would love to see more of them!
The gyro gains should be scheduled according to air speed because the sensitivity of the roll axis to the ailerons depends on air speed. Do you have any way to feed that into the gyro code?
Interesting idea, do you have any idea on how to tune the gains for the high speed part? I can't really think of anything
Reduce the gyro gains with respect to the square of the plane's airspeed.
the sound with the engine with the jet turbine really sounds like a real fighter jet
When you where painting the plane it gave mark rober vibes which is great in my opinion because your not copying his style at all but it just gives the engineering builder vibes. Great frickin video!!!!!
Brilliant project! So exciting to ride along. Pretty sure that airframe is holding it back. There is a reason most high speed jets are swept wing. Great work and all the best for all your projects. ❤
Swept wings are only useful once you reach transonic speeds and start to get shock waves. He's about 500mph short of that.
The reason most model jets have swept wings is because they're supposed to look like real jets, which do go that fast. If you look at models used for racing, they all have straight wings.
@@robinbennett5994 lesson learned! Thanks!
For the same reason, I was so surprised when I first got into the hobby to see that most of the fastest birds were 'hotliners' - essentially straight-winged motor gliders. At this end of the Reynolds number chart, that really is the speediest design!
I'd still build my own "fast" planes to look like jets every time, though, efficiency be damned. 😁 This T-33-ish airframe he's gone with is a good compromise between "looks fast" and "IS pretty fast".
This is why I subscribed. Quality entertainment.. Well played lad
The spirit of British aviation lives on!
If you can get the center of thrust to be more balanced then the jet gyro won't have to work as hard to stabilize it, possibly reducing oscillation and definitely reducing drag. That'll give you a bit more speed.
Looks like the vertical stabilizers could also use some optimization in the way of stiffening and maybe a less blunt leading edge. An expired plastic gift card is often used to stiffen foam board and you could probably just glue a piece to the outside of the stabilizers. You can also pinch the paper surfaces together along the leading edge and wrap a little packing tape around it to help it keep a more pointy shape.
The most important optimization right now though would be to paint the housing for the rocket motor to match the rest of the plane, because right now it looks like you've attached something you found in your mom's sock drawer to your plane and are taking it for a ride.
Love your videos bro as soon as I saw u posted i clicked
Okay, that was a delight to watch! So where can I buy these kinds of foam RC planes?
There's always an ejection charge. Yours just had no delay. That's a booster engine, meant to ignite the next stage.
They're super cool when they work too! I loved my two stagers
awesome vid as always! love seing you do absurd stuff to make it faster that it was ever meant to be
Absolutely awesome, could you attempt a two stage rocket motor, same build dynamics for the plane, not a lot of alterations there, but as you said the weight could be an issue.
So looking forward to the next one 🙂
I love seeing the P E R F E C T landing it’s just so satisfying
I love that you painted it Chuck Yeager orange!! Very apropos
Fastest foam plane available today is the Multiplex Fun Jet. I don't know if it's been broken yet but a couple years ago my brother set the record for the not reinforced Fun Jet at 360kph (220mph).
fastest rc plane has no engine, slope soaring extremist can generate insane speed
Excellent job chap !
Here are some things I would do to make it faster :
- swap the motor for a more powerful one
- swap the EDF impeller to a higher pitch one
- cut bigger air intakes for the EDF (usually they are too small because they are made to look "scale" but full size jet go so much faster which makes them get much more intake air velocity)
- put a higher voltage battery
- put two rocket motors on top of the airframe (close enough that if one doesn't ignite it doesn't produce too much yaw moment)
- cut the tip of the wings off to reduce frontal area, since you're able to produce way too much lift at high speed. If you're motivated you could even cut your own wings to make them make them high-speed optimised (foam covered by some light fiberglass should do fine)
Can't wait to see the next episode !
Agree with most of this but Don't cut the wings down as it will make launch and landing a nightmare.
Okay this is the first video i watched from you, but you already have my complete attention for the future.
Really engaging and fascinating stuff. Hope you become oneo of the UK's top flight engineers if that is your goal. Magic!
The rear looks like a version of a German experimental jet fighter: the he 162!
Seems like you might be encountering aerodynamic flutter on the control surfaces. Could be the gyro having an effect on it as well. You could probably try stronger servos to resist any fluttering.
This. Servo linkages, control horns, and servos themselves need to be beefed up. Any flex at all will cause this at high speeds.
Just wanted to say that your Mini is super cool. As an American who loves European cars I’m very jealous. And this whole video was just awesome!
This is awesome content actually. So unpresumptuous. Just a dude tinkering enthusiastically. Fucking around and finding out. I respect that.
Fantastic work, James! Nicely done! 😃
You're going to end up transforming the EDF motor into a scramjet engine! 😂
Anyway, stay safe there with your family! 🖖😊
Few tip you might need
~turn dow the gyro, i think its a bit too sensitive
~when you activate the rocket engine, try tome make some system to cover the air intake for the fam motor, coz i think its can reduce some drag (maybe though)
As always its a very entertaining video keep up the great work
I would love to see just how fast you can get that airframe to go on the exact same engines with some aerodynamic modifications
mark rober but with planes you got a new sub!!!!
Maybe lego flying plane?
No one wants your legos
Nice video! I remembered a while back I had a Multiplex Funjet ultra, isn't that the fastest rc foam plane? I remembered it got to about 300kmh (186 mph) in a few youtube videos.
I got one too, i flew it only once
Multiple people, including myself, reached 300 or even 400 km/h with the Funjet equipped with Hacker motor... Still using a propeller, not an EDF.
Some people even modified the Funjet to use a jet engine on it and reach even higher speeds. This video is a shitty clickbait.
czcams.com/video/sq5k0ZOCp7E/video.html
czcams.com/video/CV7uLZ5fn74/video.html
Actually beyond 400km/h
I know it was unintentional but the motor ejection was the coolest thing ever lol
Amazing video! I love watching these videos but I’ve always wondered how does someone like me who’s completely new to this field get started on cool projects like these. Do you recommend using kits at first or how do I learn about all the different components and more. Also what would you call this specific field of engineering looking into rc’s.
bro built homemade v1 rocket
tf is a 140 mh
poo
Metres per hour
They prob mean miles per hour cuz its normally meters per second not meters per hour

Miles per hour
@@rafaelmelchert722 what the hell is a miles bruv !!! ☕ 🇬🇧
set a plane on fire in the middle of a flight and see how much time it takes to completely destroy the plane. By this we will be able to see that if an accident happens in the middle of the air with the rocket engines, how much time will we have to make it land. Btw love your videos
Rockin the Park City UT shirt. :) fun video. Rockets and RC planes - Yes !!!
Fan from India
Me too
Fantastic! You've got yourself an authentic X plane! I was wondering if you'd have some pilot-induced oscillation problems at high speeds. Glad the gyro was able to adjust. Have you thought about burying the camera in one of the engine intakes?
Love the original Mini, and with the rocket motor, Chuck Yaeger would be proud ;o)
Cut the nose off and put a clear nose cap with the camera mounted there. Move the battery slightly back for center of gravity.
What an awesome try mate - thanks for sharing !!!
Could perhaps embed the camera in the rocket-housing nosecone?
Wouldn't be an over-the-shoulder view anymore but would cut intrusions in the airstream down
Dude you need to be careful with those rocket boosters because it can probably break the plane. Here's a tip: don't let the wires touch
Kevin, buy a multitool saw. It will change your life on the custom cutting/modifications you are doing. It will literally change your life.
It’s a good idea to make it orange maybe you can have a better view of where it’s going
That was awesome
Try the Insta360 for 2 for the camera. Much smaller and lighter
for your next all-out pure speed project,perhaps a swept or delta wing type with "coke bottle" fuselage area-ruling...? i could also see how the bumpy taped-over cockpit area would create a lot of drag too.
You'll achieve higher speeds if you increase the wing loading, trim a bit off the wingspan. This will also reduce the aileron area and make it less roll sensitive. Moving the centre of lift of the wing closer to the fuselage will also reduce the load at the wing root, and the stiffer wing will be less likely to flutter. Downside is of course higher landing speed.
Brilliant - brilliant - brilliant - I should add one to one of my heli's!! lol!
Great work👍💯👊
Bro you are such a legend I reallly admire
I think it ejected cause of inertia. at first, the booster had forward force in the form of thrust which was pushing it into the plane but as the force stopped. it no longer had a force pushing it forward. this caused it to eject as there was a change in momentum and it resisted that change due to its mass. hence, it ejected cause of pure physics
Wing camera video llooked like aerodynamic flutter. You may need to use.a model with a stiffer structure and mass balanced control surfaces to avoid flutter. Unlikely that your gyro has wide enough bandwidth to correct for it, even if the servos were strong enough and fast enough. Amazing that it didn’t come apart with the F engine. Good show!
Try using a soldering GUN for large joints like that. They stay cool until you pull the trigger. They'll also put out plenty of heat with 140/100 watts. You could also get an iron with a larger tip to provide more heat base. The joint won't drain the iron of heat as much with a larger tip.
This is purely next level bruv! Brilliant absolute brilliant! 👌
Excited to see use a P80.. one of my favorite old school jets
Same
I actually like that t 33...sounds amazing with stock fan..hrd to believe it only hit 50 mph..looked more like 70 from video..
You could move the tube to the side and add a second on the opposite side for balance. This would also allow you to try firing 2 engines at once (hehe)
You will need to shoot for over 147MPH to beat our current unofficial foamie speed record. We had a bit of a group challenge to get a foamie up to 200mph. Our current fastest pilot hit 147mph, there should be footage somewhere from RCfoamfighters.
You get over 150 mph with a good pusher prop setup on that plane...28 35 2300 kv..60 amp hobbywing esc
..1500 -1800 50c 4s...6x 4.5 apc prop... 5 min flights with variable throttle management 😊...you can keep the t33 airframe stock...maybe add some Cf to strengthen airframe a bit
"211mi.....211km/h"😅😅😅
Since it rolled your mind, go ahead and try breaking 200mph and I'm sure you will crack it!
Good work 👍👍👍
Cool. White primer spraypaint would make the orange look better and need fewer coats = less time/weight
i love this video and project, great job!
Add 2 engines below each wing please and also add wheels on the bottom of the plane so I can land perfectly
