Setup Tips for the CGY750

Futaba CGY750 Flybarless Gyro V1.1 for RC Helicopters

Your mechanical setup should be as pure as possible. Time spent here is time well spent.
Do all of your swashplate leveling and pitch setting with the Aileron and Elevator set to Normal mode and 2-4% gain.
Get the CG of the model exactly at the main shaft with the tank half full. Don't compromise on this.
Unless you are running at least 50% gyro gain on the Aileron and Elevator, you aren't getting the full benefit of the gyro.
Assuming a good setup with no interaction, if you still notice a tendency to pitch up at full throttle, more than likely your gain isn't high enough.
If your rolls aren't axial, more than likely your gain isn't high enough and, if you are using one of the tamer flight modes, you can try increasing to FLT Mode 4 or 5 (pg 45)
The current draw on this system is quite a bit higher than you might be used to. Be sure to keep a close eye on your receiver battery.

Be sure to assign the gyro gain channels in the transmitter to match the settings in the Sbus menu.
Set your swashplate type to H1 or Single Servo. The CGY750 takes care of the rest.
Zero out all aileron and elevator sub-trims in the transmitter. If you can't get your servo arms perfect, use AIL Ntr, ELE Ntr and PIT Ntr in the Swash Basic menu to level the swashplate.
You can use the Expo Value as it is set in the Flight Mode you chose in the Swashplate Basic menu (Pages 118-120), OR, you can use Expo in your transmitter. I suggest zeroing out the EXP.AVC and EXP .NOR values in the Aileron, Elevator and Rudder Expert menus and then setting up the EXPO to your liking in the radio. Using both can produce unexpected results.

If my gain isn't high enough, how can I make it higher?
In the Swash Basic menu increase the AIL Rate and ELE Rate so you get at least 8 degrees of deflection on your swashplate. If you can't get a value of at least 50 - 65, you can put longer balls on the outside ring of the swashplate and/or shorter balls on the inside ring. This increases the resolution and allows higher gains. You can use your AFR/DR screen in the transmitter to make it less touchy.

Are you using the governor?
I sure am. The governor is practically mandatory in order to make the gyro work properly with nitro models. I'm using the Rev Limiter mode and it's on a switch that is normally on. I find that everything works better than the default governor mode. I run a throttle curve that, if the governor were turned off, would give me a headspeed at least 50 rpm more than the governor set speed. Whenever you change modes, or just about anything in your governor, be sure to set the idle and high limits again.
