Hey everyone! Thanks for the help! Here's the fix. Autopilot still messes it up though but with a bit of effort I can at least fly it: https://www.simpleplanes.com/a/U4dh7t/Chief-Chopper
@mbmadnes32 lol it seems part of the problem is my lack of flying skills, I can't fly either of your helicopters. But then neither can the autopilot... Is this a general problem with choppers?
Love it! Just move your wings a little back (let the wing just slightly overlap the place where your fuselage taperes up) You'll find a much stabler aircraft, perfect actually!
This looks better, try using less fuel blocks and more fuselage blocks (they're lighter). Make your wings bigger and move them back slightly (to help to move your centre of lift a little further back). Increase the performance of your prop and give your jet engine an air intake or two (remember fuel can't burn without oxygen) and you still don't have elevators (found on the vertical stabilisers) or as a control surface you can add on the primary wings (pitch)
Check your centre of mass (CoM) and centre of lift (CoL), you want the CoM slightly in front of the CoL, yours is backwards so your engine pulls up, then the wings lift and the mass drops the tail causing an upward tilt... If CoM comes after CoL you'll find the engine pulls up then the plane's weight pulls down (but doesn't cause tilt) the wings will always generate an upward force, if it's too far forward it will tilt your nose up (causing a stall) if it's too far back you'll find it lifts the tail (causing a dive -this is your problem, also your CoM pushes the nose down) also remember that although you take off full power you don't need it for Straight and level flight (usually at 75%)
A note about the centre of thrust (CoT) it will emphasise any imbalance. It pulls forward so imagine in your case the CoM drops the tail and suddenly it pulls you up. If CoM drops the nose (too far forward) then the CoT pulls you down.
Also you don't have horizontal stabilisers which means you can't control your pitch (you could also add this control surface to your main wing)
Hope this helps
P.S CoL is blue, CoM is red and CoT is yellow.
I love it! For better handling I filled up all the rear fuselage sections with fuel and the "tank" below the wings I also added dead weight (500lbs) to the rear cone, no fuel for the front cone though.
Is this a made up name? I don't recognize it. Please share a link if it's a replica. Either way this is insanely well done!!

OK giving it a fixed pitch of +10 really helps, not perfect though
@TheFlyingCompany I've tried (using two engines on top, it looks like I micro Chinook) but now it goes into a flat spin.

@GrimMantis there's a 150lbs in the front nose cone, if I put 100lbs it back flips and if I put 200lbs it just drives more sharply.
@GrimMantis it tips forward and moves forward without the rear prop, then it just drives into the ground
@planes223 that bad?
@GrimMantis I don't think takeoff is the problem, I want it to have vertical takeoff and landing anyway, like a real chopper.
@AceOfSpade thanks
@GrimMantis thanks man! I've tried everything and this seems to be the best I can do, I feel like I'm missing something major
@planes223 yeah thanks!
Sweet! Thanks man!
@MaleticAirplanes is that what is used to determine race times?

There fixed it, you can find it in my profile as 'why can't nothing fly (fixed)'
@simpleOdds here you go man!

@ShatterFox 😢 wish I had a better PC!
Auto pilot!? I'm a noob! How do you do it? I'm on android BTW
I don't know how to fix it though! I think roll is also inverted...
@Flightsonic slow down buzz how did you do it?
