@mikethemark Good luck. Oh, you might want to try using fuselage blocks instead of the "Blocks" you used, as with Fuselage blocks you can not only customize the shape but add fuel and dead weight, which can help you to control where the center of balance ends up. The make sure the center of lift is slightly behind that.

@atgxtg yea i agree, i will try😂

@mikethemark Yeah that's a common problem with VTOL and vectored thrust aircraft, let alone something without wings. What you need to do is balance the craft out perfectly, and position the thrusters equidistantly from the center of mass. It's easier said than done. I've got a vehicle I'm trying to use thrusters just for vertical take off and it's tough because I have to move the thruster every time I change something.

@atgxtg 😂that was an aciddent because i was changing the cockpit style,but the main thing is that it can not be controlled properly without the gyroscopes

@mikethemark You're welcome.
Let me guess it was #1 that was causing most of your problems, right? It's what caused me to crash.

@atgxtg thank you very much!!

You just overcomplicated every Part of this Plane

Nice design.

1)First off I strongly suggest changing the front cockpit to the primary-it's probably a major contributor to the control problems and crashes, as the plane isn't centered on the spot you'd expect it to be, and your camera angles are off.

2) Increase the range of motion of the rotators for the engines. I'd say at least 45 degrees, as that's the angle where you get the best trajectory, which should help with takeoffs and reduce runway distance needed.

Other than that:

3) Adding some Pitch, Roll or Yaw ability to one or more of the gyroscopes , and/or adjusting their stability can give you better control and stability. Or, more commonly, better control or stability.

4) Adding some dihedral,and antihedral to the wings, front and back, will make the plane more stable.

Good Luck.
