you dont thats how the system works lol think of it as  spinning faster or slower to try and keep the tain locked in place the tail always wants to spin clockwise from the torque of the main blades so for it to keep  the nose pointed in the way that yyou want it to point if the gyro sees it turning either way then it adjusts the speed on the tail rotor. where as the belt/ torque tube tails are being spun at a certain speed from a gear ratio so the blades actually pitch left to right driven by a servo to try and keep the nose locked in. if i were you i would set gyro gain and then only adjust the gain on the 2 in 1 under the canopy theres a sweet spot for them to much gain and u will see the tail wag not enough it simply wont hold.
