I have a R50 and a R90 both with 502,s and I cannot get the tail to hold solid in fast backward flight. I have the gain set to just below the tail wagging and no luck. They both have carbon tail blades also.
Can anyone out there help?
Thanks Mike.

Ok here are the specs:
Raptor 50
13.5 centerline of ball from center for servo arm.
GY-502/9254
1950 Headspeed
57% gain

Raptor 90
13.5 centerline of ball from center for servo arm.
GY-502/9253
1900 Headspeed
55% gain

Is the 502 not enough gyro or do I have setup issuses?
I will try ANY suggestions.
Thanks Mike.

13.5 is on the 'too short' side.

definitely move it out 1 hole (3mm), *maybe* 2 holes.

What z11355 has said,

Except i would go even further out, fairly certain mine is around 17mm.

Out of interest what are your limits in the AMP set to..

Thanks guys I will move it out a hole or maybe two. I think that my amp is set for full mechanical travel, I will check to see were that is.
Just out of curiousity what gain setting are you guys running with the long arms?
Thanks for the help.
Mike.
