Well - which heli is it?
Could you attach some pics, especially antenna monuting?
Does it have a belt drive?
If yes - how is the anti static hookup?
Is it an electric?
If yes - how is the motor/ESC cable insulation?

Okay - please do test runs on the bench w/o blades.

Please mount a anti static kit which connects all shafts, pulleys, boom and motor plate.

Also - post me the result (Screenshot) of a range check according to our instructions:
