My mcpx is lazy in IDLE UP

[moejammin]

I have a brand new v1, airmax 7a converter/esc, co5m, sr120 tail motor. I just put this upgrade together on a brand new heli. I have my power coming from the esc and not the 3in1. In normal mode everything is fine,but in idle up the nose spins about 15* to the right and as its doing it you can hear the rpms drop significantly. I have used this motor before on an xp7a/aeo setup with no problem. Any help is appreciated.

Do you have your throttle curve setup correctly?

[moejammin]

I think that I do, I use a flat 100% in idle, with 70% pitch.

70% flat?

[moejammin]

70% up and down in the travel adjustment menu. And in the pitch curve menu its 0-100 linear.

Sound like its ok there. Which converter did you use?

[moejammin]

I got the airmax 7a esc/converter.Using the stock settings. The sell them at tmkarc1hobby.com. I have read they are the same as the oversky 6a esc/converter.

Does anyone have any idea. Ive checked feathering and main shaft, main gear, gear mesh, connection to tail was tinned. But the problem still persists. After changing the gear and main shaft it was a little better but when in idle up the nose still shoots to the left a little.

Is the nose shooting to the left or to the right (original post says right)? What tail prop are you using? Whats the distance from the tail motor shaft to the center of the main shaft (should be around 150mm)?
