well, if you want to control the plane, you have to buy the RC (Radio Control) Upgrade. but even with level 1 RC, the Plane will not fly for long..
the 1st rounds are just build-up money for other abilities such as RC, Ability Rate and Arm Strength (all of those are main ability) once u get few stats into those, you will be able to control the Plane to the SPACE!
its grindy little devil game haha
