mount the gyro label up towards the sky, right side. connect the gyro to your rudder on the rx and the single wire goes to the gear. put your gyro gain to max. Now on the dx6I settings,, scroll down to gyro menu on your right where it says gyro, switch that to F.MODE this way you will always be flying on a head holding mode, Just in case you accidentally flip the rate/hh mode switch. On the percentage part, start about 78% on 0 and 1. They must be the same ok ? If the tail wags too much, lower your percentage by the increments 0f 2% , Keep spinning it up until it holds the tail solid. Good luck!
