not easy to control!
the car engine be modified to control with the throttle instead of pitch because pitch is used to control the flying mode
so, activate button 1 to start flying mode, throttle and mouse as stick, but you should not speed over 130 when flying straight line or it will tremble very much when maneuvering, you must throttle to 100% because it lost speed very fast, all in one sentence, you should control throttle all the time quickly
now I find any user of SimplePlanes could find this page from the next version of this model, so I should write more about this model, I have uploaded a video of this model to youtube, the link here:
