Futaba CGY 750 help
I am new to FBL. I have a Trex 700N with a CGY 750 and a 8FG radio. Can anyone tell me how to make the 750 less sensitive? I am running flight mode 3, Ail and Ele rates are at 50%, Pit rate is at -29%. Collective pitch is 11 degrees positive, 11 degress negative, zero at center. 8 degrees cyclic. I have tried flights modes 1,2,3, and 4, all modes seem too fast for me, how can i make it feel more like a flybar? Any input would be greatly appreciated.

You need to go into your aileron and elevator gyro expert settings.
There are menus in there that should help in what you're looking to achieve.
Pages 98 thru 106 in the manual.
or maybe Dr. Ben can chime in.
My expert menus are at the default settings. Its quick but not as quick as I'd like it to be.

OK.

Put the system in flight mode 2.

Go into the AIL and ELE EXPERT menus and put the AIL AVCS.DMP on AIL at 98% and the ELE at 100%.

Set the AVCS EXPO in the 750 on both AIL and ELE to 0%. Then set your AIL and ELE expo in the transmitter for now to -40%. You'll tweak that later to taste.

Reduce the radii of your servo wheels a few mm so you have 8 degrees at more like 60% AIL and ELE swash AFR in the 750.

For your hover mode only, I want you do reduce your AIL and ELE dual rates to 75% each with the expos as described above. That will feel pretty mild. Then go into idle up with the d/r at 100%. Set the idle up expos at -20 for AIL and ELE. Do some basic aerobatics and see what you think. If the pitch and roll rate is still too quick for you, then reduce the swash AFR's by 5% or so.

If you get the pitch and roll rates to feel nice but the system now feels a little slow off center, then either reduce the expo a little or go up to flight mode 3 and keep the AVCS.DMP values where they were. Make sure you go back and reset the expos in the 750 to 0. You only want expo in the transmitter or the 750, not both places, and when you change flight modes, a lot of this kind of stuff resets.

Try that and let me know what you think. I can make this thing pretty much feel exactly like you want with just a few suggestions followed by some feedback from you.

I can't thank you enough Dr. Ben. You were right on the money with your advice. It flies like a champ and it will allow me to adjust to flybarless. And thank you for making it easy to understand. You are awesome!!!
