The cardinal rule with all flight controllers.
Don't do any mixing and/or reversing in the Tx. Do the mixing and/or reversing in the flight controller.
If you violate this rule, your gyros will be wrong, instead of saving you plane they will crash you plane.
AND, make sure that when you move the plane, the gyro moves the control surface in the direction to counter your movement. Just because the sticks move the control surfaces in the correct direction does not necissarily mean the stabilizer is configured correctly.
Been using flight controllers almost 10 years now, and I violated the "check the gyro reaction rule" last spring. When I engaged the gyro in flight, the gyro immediately pulled straight up, stalled the plane, and I had no time to flip back into manual mode or recover.
