Futaba 611

[tilburyboy]

Hi everyone,

I have been using the 611 gyro for quite some time now on all of my nitro heli's , flies perfect in normal flight, but when flying tail first or do a pie dish the tail will spinout and go round as much as 180 degrees.
I have tried setting the gain both high and low, but my starting point is 37% in avcs heading hold and 75 normal.
This happens on all 3 helis i have with the 611 so must be a setup fault by me.
Also they are set in 3fc mode and not 3D, as suggeted by the man himself
Alan Szabo Jr.

Any help most grateful.
