i need help with the set up of said heli, the trouble i have is that i cant seem to get the blades to turn fast enough,when hovering the engine is bogging down eevn though i dont have much pitch and throttle is at full speed, i need help with the pitch, throttle setting and fuelling, can any one give me some figures they use on there raptor for throttle curves against pitch cuves and how many turns on the mixture screw for fieling, i have tried alot to get this sorted on my own but now am getting stumpped,

Read through his articles, you shoud find what you need, if you have specific questions, ask away.

I moved this to the Raptor section from the Scale Helis section since this doesn't seem to have anything to do with scale.

If your engine is TT PRO 39 try 3 turns the high speed needle and 2.5 to 3 turns the low speed metering screw (that into the carb barrel). It works for me using 15%nitro cool power. Idle is rich but it needs to be rich in order not to run lean at midrange.

ah cool will try that, the engine is a nasty mds 38

The number of turns i have given is for TT39 and may not work for MDS 38. I think that the start point for MDS 38 low speed metering screw is 1.5 turns. Not sure about high speed needle.
