I have a wag that’s not the same as a high gain setting waggle. It happens in HH and non HH mode as well. Checked boom, Belt tension from one extreme to the other. Checked tail shaft. Replaced tail assembly with all new parts. Even tried unplugging the remote gyro plug from the receiver and ran it with the gyro settings from lo to high. Still wiggles. Replaced servo and Gyro. Still have the slight shakes. At times it will take an unsolisitated jump to the left. I can catch it and bring her back to the original heading and after about 20 or so seconds she jumps back to the right. Again, these actions happened with the old gyro and servo and continue to happen with the new parts. I’m at a loss. Any ideas what is wrong?
