I am now setting my Trex600E Flybar machine on a new FASST R6208SB reciever.
The heli was picked up on RR a while back & set up on my 9Z 72 Mhz setup, with FP-R148DP PCM1024 receiver & 9256 servo.
I had flown the heli before, a few times but not alot.
It used to hover just fine & some, but very little FF had a solid feel with the 611 gyro set up the way it was by the original owner. I just in used 85% gain on my transmitter in the DUO mode, however only used in that Gain 1 setting before.
Now for the issue, I am not familiar with the 611 gyro.
After installing the new R62008SB reciever, the tail had a fairly bad shake, like the gyro was way to sensative. so I turned it way down on the transmitter with no effect.
I finally changed the gain ONLY on the gyro control to 50% from 95%, & transmitter up to 95% gain. No wag on the tail.
Things seem OK
I think the new reciever processes data faster then the old one, I tried both normal & HS modes no difference, left in HS mode after test.
I will next be doing more FF tests.
Again I am not familiar with the 611 gyro, and instrucions are basic.
Wondering where to go from here?
Any tips?

Make sure the gyro is set to CMT so you can select between avcs and rate modes and tune each from the transmitter.

You can simplify life by skipping the gyro menu and just using the atv for each flight condition for whatver channel you are using for gyro gain. One side of the atv is for rate mode and the other will correspond to avcs. Typical idle up gain will be in the 40's depending on headspeed and tail blade length.

May have found the issue
It turns out, that the "Throttle Hold" & "Gyro" were set to same switch on the 9Z transmitter "So many settings on this Bad Boy".
After checking "Normal" & "AVS" operation I dicovered that they were conflicting & not working at all.
Weather is real bad here today.
I will test fly ASAP.
Thanks for your help, it led me in the right direction.
