I bought an old Blade 450 3D as my first helicopter and it's behaving odd when I try to take off. As I increase the RPM before lift off the fuselage suddenly starts to spin. I think I've done the settings on my TX right. Could this be related to the gyro?
Sorted out: I replaced the Tail Rotor Pitch Control Slider and did the assembly wrong. The Tail Rotor Blade Grips was mounted in wrong direction. I must have reversed the tail rotor stick on my TX, but the gyro setting was still in wrong direction. So the gyro accelerated the tail spin instead of stabilizing.
