- Replaced a block to a tank behind the cockpit to put the CoM higher.
- Replaced the front wings with just one wingpart and deplaced the wheels a bit more outside to improve the retract function.
- Removed the full in the wings that the plane doesn't overroll anymore.
- Changed the settings of the prop engine from AUTO to FIXED with 70% pitch.

Note:
- While the whole takeoff max throattle to 80% and pitch up. Othetwise the plane will crash.
- Once in the air throattle to 100% and retracte the landing gear, wait until the speed reach 320mph and the plane will fly perfectly stable.
- Only 59gal of full but I think it should be still enough.

I hope you will be satisfied @LordofLego
