Hello
Problem with my engine:
engine 200 cdi , prop 21.5x10.5 , fuel morgan cool power 30% heli
main needle open 1 1/4, The regulator is slightly open half a turn from manufacturer mode
On the ground everything is fine , mex rpm 7000 , idel 2000 rpm
In the air when I rise above half throttle , hear a loud, strange noise like detontions
And I also see that there is a mismatch in the smoke ,
Do you have suggestions what to do ?
thanks
Kobi
