This is a versatile race plane with very little aerodynamic drag. If you start on the ground, hold back the elevators until you reach the max speed of the launch vehicle, which is approximately 250 mph. Then engage the detacher with activation group 1. This should lift your plane free of the launch vehicle. This plane is capable of sustaining 650+ mph in high-G turns. If you start in the air, simply delete the launch vehicle first. If you are in a glider challenge, delete the engine and remove the fuel from the fuselage. Controls get mushy below the 300 mph range, so it’s not a good choice for the tighter race courses. Thanks for viewing.
