You need more headspeed for that position of the throttle stick.

Hi there,

I had the same problem & found out that the cause was VERY EXCESS PITCH at hovering throttle position. PLEASE CHECK your pitch as measured with a pitch gauge at hovering throttle i.e. about mid stick

Regards

Pitch is something you usually measure and FIX.  It is the throttle needed for that "pitch" (which I put in my earlier post as "that throttle position"), that varies, as there is no easy way to measure/calculate it.

If you are just beginning, you typically want the heli to hover around the 55% to 65% stick position.

Thax Anwar Ji
I have set the pitch around 5.5 degree at 55% throttle with lower is -5 and upper is 10.
I think the engine setting is very rich so i will try to lean out the enginea liitle bit and increase the the head speed as  u suggested earlier.

THAX Mr Anwar
The problem of tail hunting solved by increasing head speed as suggested by you.
I have incresed throttle curve by 3 % on position 3 and 4 also made the engine lean by 4 clicks.
once again many thax for your valuable suggestions.  Smiley
