Anyone have recommended settings for a 700 DFC w/ Align HV sx & CGY 750 for rudder gain? When I checked the Rudder gyro gain by left rudder hard then let off and then right hard then let off, it makes a higher pitch bzzzzz noise. When I punch out or load the disc it does it as well.

Sweet baby jesus, did the first flight on my 700E DFC. It was sweet until I starting doing piro's and the tail let go. The Screw came loose that holds the control linkage on. I auto'd down and because I haven't been on FBL since 2012 I got it on the ground and rolled it over. Not a single bit of damage thank the good lord! I bled off most of the head speed before the skids touched down.

Settings for Gyro gains,
Rudder 65% AVCS
Aileron & Elevator 55% AVCS

So, a little update, I fixed the tail, got it flying again and started turning down the rudder gain, it helped a little but I still have the bzzzzz, I also some bzzzz, bzzzz, bzzzz, and wagging in fast forward flight as well as rolling and elevator tic tocs. I also tried my radix tail blades which are 105's as well and this helped very very very slightly. Should I bump up to 115's?

Sounds like the dreaded hum...

-edit- sometimes the hum doesn't go even when changing tail blades

Figured it out, Gain on the Governor was too high. Went from 20-25 and then back to 15. At 15 it worked great. even turned the rudder gains back up. I may end up putting the gain back up to like 17/18
