Building the WORLDS FASTEST RC Rocket Plane!

[@morganmade1845]

When soldering, I find if you put the iron underneath the joint and let the heat travel up it works much better.

[@almaefogo]

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.

[@neayt9952]

The Iron is too cold/too weak/old wire/bad solder

[@Youtubeiscoolandgreat]

Yeah the soldering did look dodgy

[@meanderinoranges]

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.

[@sadface]

@@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.

[@ChrisMisMYhandle]

yes, they make motors suffixed with P, which means they are plugged - no ejection charge

[@constantin1004]

Correct!

[@Sniperboy5551]

You took the words right out of my mouth

[@theredstonehive]

the ignition charge is also just the end of the propellant grain

[@spud4242]

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.

[@JAEUFM]

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.

@@ewanfarley 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.

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. 👍

[@brianward7550]

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

[@wilgarcia1]

@@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 =)

[@tinderboxcreations]

@@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.

[@KutWrite]

[@benanddadmechanical6573]

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.

[@mrbyzantine0528]

I initally thought making a wingtip pod for it, then the idea of mounting it in the removable canopy came to mind.

[@Brandon_SoMD]

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.

[@warbuzzard7167]

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.

[@ayyhmed]

great explanation. thank you

[@BreakWindDrone]

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

This is why I subscribed. Quality entertainment.. Well played lad

[@robertfpv7733]

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

[@hemi-pilot]

What about installing the camera into the nose. That would negate part of your CG problems with the heavy rocket engines on the tail.

[@ryanmartin5668]

Reinventing and reviving the good old JATO pack! Great video and even better garage engineering.

[@nighthawk0077]

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

[@droneracerswarehouse7641]

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

[@Realism0000]

[@TheTonester2312]

This is amazing. Love that whistle on the last rockets ignition. Super cool 😎

[@beachbumberry]

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.

[@joebo9378]

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.

[@AmishFan]

This is awesome content actually. So unpresumptuous. Just a dude tinkering enthusiastically. Fucking around and finding out. I respect that.

[@hemi-pilot]

Nice video as always, but you should seriously consider getting someone to show you how to solder properly.

[@billpolits7594]

Cool! Put in a bit of downthrust to avoid the nose down pitch on rocket ignition. Also, is that a model rocket engine? If so recommend providing forward outlet for recoil charge (meant to eject a parachute. Didn’t have time to watch whole video, and others like have said similar… just in case

[@engineeredlifeform]

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.

[@andreasvox8068]

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?

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?

[@rizalardiansyah4486]

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

[@richardm.newlands2417]

Reduce the gyro gains with respect to the square of the plane's airspeed.

[@silvervibranium2832]

I love that you painted it Chuck Yeager orange!! Very apropos

[@bobhawkey3783]

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. ❤

[@robinbennett5994]

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.

[@bobhawkey3783]

@@robinbennett5994 lesson learned! Thanks!

[@rcbinchicken]

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".

[@princeinpve]

P-80 to Unmanned Surveillance Drone, maybe you should add a camera facing down.

[@Advil1024]

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.

[@hookedonhobbies9825]

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.

[@Argosh]

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).

@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.
