Firstly i desided to make a plane so small that the propellers diameter was bigger than the fuselage. Then i ran into a problem with the takeoff and before i knew it, my mini project turned into a rather large one. Instructions is as follows.

Throttle up 100% at first.
Press 1 to fire the main engines.
*Watch out under takeoff, it will tilt because of the long landing gear.*
Press 2 to drop the landinggear.
Gain around 3000ft of hight.
THEN press 1 again to turn of the fuel consuming main engines
*important to keep fuel level up*
Press 3 to release the experimental plane.
This step will also release the main engines from the cargoplane.
And at last.
Press 4 to fire the propeller engines.

Mess up the order of steps and suffer the possible fatal consequenses ;) Enjoy.

Oh yearh its a kinda one way ticket this one.... Landing will be impossible. :)
