This is interesting...It said: Use ±45° bias plies to resist twisting and 0° for bending strength.

Idk what that means…🤔

I think it means the layers, like how they are arranged..Like with pli wood a lot of time you have the layers 90 to each other.

Oh yeah, I’m too simple to understand 😂 (unless it has to do with engines)

actually forget it im not gonna be like that 300 mph funjet dude

Issue with ramjet is that u cant find it anywhere if u want u gotta build one urself and Issue with pulse jet engine is that u also cant find one anywhere the ones I have found produce like 2kg thrust so it isn't powerful enough so im gonna use a massive solid rocket motor......

yes im gonna use 2mm thick carbon

U asked chatgpt........our generation really is cooked........

so yeah I just started a new forum to discuss the 400 mph plane
khuzaima
Elite member
ok new thread is posted where im gonna disclose all details about this new plane

Well I was already thinking that, I was just wondering if there were any other things we should take onto consideration besides what we were already....You would have to look it up on the internet and probable just read the AI answer OR I can just ask there and not have to go digging around on 100 sites just to find how thick you generally want...

hmm I didn't see it that way I guess that is true

yep, there is still a lot I have to go watch YT video's on or read blog articles at places...Or ask here!

Here is a run down on your option by Chatgpt...
To hit 500+ mph in an RC aircraft, you’re well beyond normal EDFs or prop planes. You're in the realm of experimental, high-speed designs, and here are the most viable options:
(But most turbine RC jets cruise around 200–300 mph)
If your goal is record-breaking speed, then:
To hit 500+ mph in an RC aircraft, you’re well beyond normal EDFs or prop planes. You're in the realm of experimental, high-speed designs, and here are the most viable options:
🔥Best Options for 500+ MPH RC Flight:
1. Rocket-Powered RC Plane
- ✅ Fastest method — Easily exceeds 500 mph with the right design.
- ✅ Lightweight and simple airframe
- 🛑 One-shot flights unless using hybrid or reloadable motors.
- 🛑 Limited control time — short burn, glide back or parachute recovery
2. Turbine Jet Engine
- ✅ Real jet engine — extremely powerful and realistic
- **✅ Reliable throttle control unlike rockets
- **🛑 Very expensive ($3K–$10K+)
- **🛑 Complex to operate (kerosene, preheating, maintenance)
- 🛑 Heavy — needs a large airframe to handle speed and fuel
(But most turbine RC jets cruise around 200–300 mph)
3. Pusher Prop + Rocket Assist (Hybrid)
- ✅ Electric or gas prop gets you in the air
- ✅ Rocket ignites mid-flight to blast past 500 mph
- 🛑 Complex ignition, safety issues, hard to test safely
Not Feasible for 500 mph:
- EDF Jets — most max out ~200–250 mph, maybe 300 with extreme setups.
- Ramjets — need to already be going fast; hard to ignite and maintain at RC scale.
- Pulsejets — possible, but wildly inefficient and dangerous for controlled flight at 500 mph.
Summary:
If your goal is record-breaking speed, then:
- Rocket-powered delta wing is the best way to actually hit 500+ mph
- Turbine jets can push 400–500 mph but are expensive and hard to fly
- You’ll need excellent aerodynamics — low drag, high structural strength, and fast telemetry or tracking systems

Or there's this......
Pulse Jet Engine Gasoline Internal Combustion Micro Valve-Controlled RC Model RT | eBay
Promptly clean the fuel nozzle if dripping occurs. The pulse jet engine, a type of jet engine, with a simple structure and higher combustion efficiency compared to regular internal combustion engines, was initially used in missiles.
