Revo Mixing and GY401?
Just did a test on my skiddy and 401. You can not use revo mixing and HH. As you turn on the gyro in HH, If you have revo on, as you move the collective/throttle up the revo moves the t/r. If you hit HH, and your stick isnt in same position as when you turned gyro on, the gyro will think its not centered. It will go into a dbl blinking error light on gyro. You will then need to reset neutral position by turning on and off the hh 3 time within 3 secs. But the same situation will occur if you move the collective. The gyro will then go into error mode again. Ive crashed when I didnt realize this on the first flight with this gyro. The tail swings left and right violently trying to find neutral and I tailed it in the ground. Learned the hard way I guess....:-)
