Hello Everyone!

I have TZ30 (it's like raptor) heli with Hirobo 36 engine and I have some problem with the tuning.

when I put the throttle stick at 1/4 way the engine sounds like he's on full power.

I checked that the stick and the engine are running the same way (if i put full-stick the carborator is opened the fullest, and so with half-stick and in idle mode)

my th-crv
p5-100%
p4-75%
p3-50%
p2-25%
p1-0%

what should i realy frustrated?

thanks!
Amit
