Building the WORLDS FASTEST RC Rocket Plane! (Part 2)

This went from being a plane to being a guided missile with enlarged fins…

Some GPS have built in protection that disable GPS module above certain speed to prevent using them in rocket guided missiles ( such as the one that you've built) Maybe try UWB localization methods ? Best of luck !
EDIT: After reading datasheets of couple cheap GPS modules it seems that they have a limit of 4G acceleration then they shut down for legal reasons. I think that's more probable cause than speed limit.

Pro tip: The back of the craft is as important as the front when it comes to aerodynamics. Maybe try making the adapter conical next time to see if that helps.

This reminds me of how the X 15 would be released from a mothership before using its own engine to get it to Mach 6.7. So cool

This is such a cool series! Really enjoying watching the progress

I watched 4:12 like 15 times!! That sound is incredible!! Makes me wanna build one!

Your goal should be somewhere around 200mph, if you want it to be the fastest foam jet.
One of my Multiplex Funjets reaches 188mph and there are many even faster ones.
[Edit] Actually, they already reached 250mph with foam jets. See comments below.

Would love to see a third part where you launch it from another bigger plane and use a gyro to help you keep it straight. I think targeting 200 mph would be very fun as it will need to be more reliable as well.

Amazing how a toy that started out looking like a P-80 Shooting Star, has ended up looking like the prototype V-1 bomb that had a pilot for development of the airframe.

This was so creative, from how you dropped the aircraft to keeping the rocket motors from falling out. Keep it up bro, really loving these vids

Insane results! I wonder if a big part of the reason the GPS recorded excessively low is because its sample rate is low enough that it didn't catch the full turns and thus misjudged the distance traveled. It would be handy if you could adjust the sample rate on it

I'm always impressed by your creations everytime

Have you plugged the boosters with compressed cat litter to prevent the engine casing from ejecting from last time? The reason I am suggesting this is to make a more powerful and completed burn of all the propellent the engine has, like the A10-P.

I love what you do and your endless enthusiasm, juts a question on this series, other than the Bell X1 when did you last see a high speed aircraft with a straight wing? Maybe a swept wing would be better? Keep up the great work

10:30 sound quality on this onboard was impressive!

I would have liked to see you testing the GPS to replicate the failure.
No worries I'm sure you can add that as a clip on a relevant video.
If you keep building ultra fast things you will need to find an alternative! Keep it up, great video

I'm not sure how reliable the Velocity from GPS is. They use the dopper effect to get the speed which accuracy is debatable. Aircraft to this day use piot tubes for airspeed (also a thing bc if you fly into the wind gps is ground speed). And there are ones for drones aswell with i2c connections. Just a suggestion. Awesome video!!

You're very talented! I'd like to see more content like this.

I was hoping you would take this project further! Yes it's original brief has been met, but longer flight times and a proper take off would have been very interesting.

If you do ever come back to this project, you should make a "catapult" launch system like they have on air craft carriers

It looks like it’s about to slam into an American ship at 700mph for the glory of the Emperor of Japan

I'd like to see what speed could be achieved with a swept wing design. Maybe even a Delta wing. It's that straight wing slowing things down.

Man! That second rocket powered test was amazing! You absolutely crushed the timing on it! So glad my name got to go for a 145mph ride 😅

Fantastic video! I would love to work with you on part 3 of this project if that is possible somehow?! I have also wanted to try a rocket for a long time. I think you could go way beyond 400kmh even with foam. A Funjet airframe is already capable of 400kmh+, so we can easily build something better than a Funjet. Do you have access to bigger motors or is the max legal size? I know Ceasaroni do some huge motors, but don't know about the laws here in the Uk. Do you want a colab for pt3? I actually don't see why we couldn't challenge the outright record for pt4.. It would be possible go beyond transonic with a small delta and the biggest motor we could get hold of, maybe work with a licensed rocketry specialist to get access to the big boy motors!

To make it even faster you can do more of a wing swept design and thinner wings

Fantastic work, James! Really well done! 😃
But yeah, the GPS module got a bit too scared to register it correctly. 😬
Anyway, stay safe there with your family! 🖖😊

I saw the thumbnail as a scale MXY-7 and figured the landings would be interesting.

Look how green the grass is ❤❤❤ absolutely why I love the UK and Ireland.

That last flight definitely looked a lot faster. Way to hit your target!

Great work man! That looked like it was pretty fun actually!

This is one of those videos that you press the like button before you even watch it.

12:22 the barrel role was pretty sick

You can see a major issue at 1:02 - Your wings and ailerons are wobbling under excess load. I had this issue all the time when running foam models with electric motors that had 5-10x the recommended wattage, great fun btw, nothing quite like seeing a drivetrain being ripped out of a poorly reinforced foam fuselage..
Anyway, the best solution I found for wobbly wings was a carbon fiber spar. I used 0.5mm and 1mm thick flatstock that was wider than the thickness of the wing. i then cut the wing all the way through lengthwise and used contact cement (UHU POR) to glue everything back together, then dremeled off the excess carbon fiber material. You would not believe how stiff such a wing was, afterwards. For ailerons, I reinforced the root of the wing cutout in a similar fashion and then used fiberglassed balsa ailerons instead of the original foam ones. They tend to hold the torsion forces much more reliably.

Maybe the gps sampled at 1Hz and wasn't able to get a good fix on speed within a short curved flight. I wonder if the rapid change in altitude affected the gps accuracy. The gps receivers I've used were quite slow to update altitude changes.

A propeller in the nose would remove the need for a drop and still have aligned center of thrust and center of gravity. Also a wing high up on the fuselage or a strong dihedral wing angle could minimize wing strikes on landing and make the plane more stable in flight.

I love your videos. It's amazing to see how dedicated you are to finishing a project and giving it all you got. From watching your videos I was inspired to design my own RC Hovercraft and was able to finish it and have a cool and working design. Thanks for you amazing content and your inspiration to people in the hobby.

Congrats, you just made a plane-shaped rocket

Looks just like the Yokosuka MXY-7 Ohka which is a Japanese kamikaze rocket plane from ww2. A horrible thing to be compared to but I saw the resemblance instantly

Absolutely love your content very informative and inspiring and just down right cool

Nice Bell X1 there. Congrats on breaking your record!

Funjet ultra is doing 250 mph plus. OMGOOLIEBIRD channel posted it 6~ years ago. Maybe YOUR fastest rc jet- lol.

You should make a GPS guided cruise missile of some sort. That'd be cool

That looks like a Japanese OKA suicide Plane from WWII. Americans named it BAKA, means Crazy!!!! Look it up!!! Outstanding WORK!!!

Great job James. As entertaining as it would be to see, I'm glad it didn't end in a flaming pile of foam and electronics.

Great series. I love speed as well. I'm building a very small boat to see how fast I can get it going starting with a 25 HP outboard motor. Then maybe a bigger outboard depending on how the boat operates at speed.

Brilliant project. Loved that. Thanks.

For the camera mounting, I was expecting maybe mounting it in the nose of the aircraft, with a clear aerodynamic cone to cover it. Your idea is much better though.

You need a swept wing design! That will make it go even faster!

air-dropping a rc-plane from a quad-copter? it is so simple, it is BRILLIANT!

Holy cow, the brits are really adjusting to the metric system, inch by inch :D

The sound it makes when the rocket ignites is absolutely beautiful ❤

You designed the plane itself so well, I think it may be time for a bigger motor 🤙

5:47 bro that's when i realized you're a pure genius!

congrats, don't sell yourself short you guys always do great. personally Looked closely at landmarks my figure was more like 147/148. regardless its just fun to see what you are up to, never a dull moment...

Your vlogs are brilliant. I always look forward to what your next project will be as well as your enthusiasm.

This video is fantastic. Well done . It looks and sounds so incredible

Oh sweet! A part deux! And it's aero! Woooo

Barrel roll at 12:21 ....... Best part of the video!

The camera holder looks like a cockpit for the aircraft, so it fits quite well.
Awesome plane man!

Disassemble that heavy, bulky camera. Build a paper thin teardrop/Venturi shaped pod
for just the CCD part, extend the electronics package into the fuselage with an umbilical
ribbon cable.

So impressed and love the plane it do be being like sanic

This guy can make a foam plane into a mini rc jet.

Those cocktail stabilizers are such a Kerbal solution xD

James, fantastic work. Congratulations!🎉🎉🎉🎉

A Bell XS-1 would be a perfect model for the flights.

Dat last minute pull up in d last flight🔥🔥🔥

Project success! Congrats James

Terrific job - incredibly fast and very precarious.

I love how, other than the tail design, you trial and errored your way to basically recreating the Bell X-1.

I would say that leaving the camera off could easily gain you 20mph. Creating a clear naca shaped shroud over it should gain you most of that speed. The gains from the shortened wings and the sharpened trailing edges of the wings would be nothing compared to the blunt body of the camera sticking out the top of the airframe.
Great result with a fairly low tech build.

Awesome video, thanks for taking us on your flight.

Hot glue and duct tape. :D
Professional grade.
Seriously.
Good stuff.

I love everything aviation, you are my ideal KRplus channel.

Pro tip: put a live camera on the front of the plane to see where it is at also so you don't need to look up

Just a little idea for the camera: place it inside the body in an upright position and attach a mirror at 45º to the lens, so it still records back footage, but now with a much smaller footprint

The flyby was unbelivable!

Omg that was amazing

I would be so pumped if I was the manufacturer of that airplane to see how far its come

I have to say your workspace makes me quite envious

1). Recess the motor into the fuselage,
2). Make the motor mount hollow to allow for airflow throught the mount,
3). Open the air ducts and let the venturi effect increase thrust

You could also try to search for another rc pilot and let him hook your plane into the air. In this case you already have good speed and the right direction.

That was cool 👍🏼 also like your RC Spitfire 👍🏼👍🏼

I wish I was this passionate about a hobby, well.. anything really! Great video mate!

You could also add a servo onto the plane and make a vent into the edf that when you would flip a switch it would close the vent allowing for the aerodynamics that you need for speed while also allowing for independent flight before and after the rocket is ignited

That was great! It would be a nice one to drop from a Lancaster. I'd love to see you capture those numbers.

I buy your estimated speed from the ground landmarks, that final flight was DEFINITELY faster just judging from the video.

Love how the orange paint makes it look like the old X1.

Awesome video James! Nice to see you have found a cameraman.

that sounded so cool. Great job ! Cheers

Good stuff lads, well done 👏

You were probably calculating the ground speed, which is the speed that travels on a 2D basis. A better way would be to use (indicated) airspeed, where it measures how fast you are travelling while also accounting for vertical speed, similar to the ones used by a jet or commercial aircraft.

10:13 seems like the interstellar detach scene when the smaller ships drop from the bigger ships

Ah, the Bell X-1 approach to a fast plane. There is no need to use energy to get up to speed or altitude. Smart!

Congratulations. Excellent work, well done Sir!

Love this content. Really looking forward to the car.

You should make detachable and reattachable wing attachments that are basically more wing and add turbo fans on the smaller end of those wings and a little parachute on the far end of the turbo fans so that when they detach, they open up. Detach the wing attachments before you burn.

Love the series! Thank you for the content. The GPS may have failed due to you taking a slightly more vertical flight plan or that the satellites being to far away or not being able to track it.

Seeing it after the first test flight was a gut punch NGL

I would definitely watch him 24/7 if he uploaded more frequently

I would have attached engines to either side of the fuselage of the first design (maintaining the ducted fan and stability controls) with the addition of the new canopy and camera housing.
