I've finally finished the plane, and I am very pleased with the outcome! I hope you like it as well. Please give credit if you use this rig.

It includes:
Animatable Propeller, Wheels, Fins, Steering wheel, and more
Built so that a character can fit in nicely
Comes with two folders, so you can animate it better during takeoff and turning
No streched textures(should be no Z-fighting either)
