Raptor 30 dos not stays at a same altitude
Dear all friends,please help.What's the reason, why my raptor 30 which has pro 39H(R) engine dos not stays at a constant altitude , i mean i dont move throtel stick but engine R.PM. goes slightly up and down ,it dos not stays stable so my helicopter looses/ gain's altitude continually. WHAT THE REASON?please suggest i am using Tx Futaba 7c, it has 5 pint adjustment for throttle & pitch curve's.thanks & regardsthanks & regards
