RE: LMH 120 tail problems (not with the casing breaking)
Hi Josh,
Which gyro are you using? Does the tail continue to turn or just to 90 then stop once you get into a hover? If the model is turning (nose right) only 90 degrees when applying throttle, the gain may be set too low. If you are using a HH gyro and the tail is continuously drifting in the same direction, the problem may be that the TX trims or sub trims are not set to neutral. Or the revo mixing is not at zero. Also be sure the gyro is isolated from vibration by mounting it using foam tape. Vibration in the model along with a low gain will also cause the tail to drift (nose right). In any case you should try to reduce the vibrations. Primary contributors to vibration would be: bent MR shaft, bent stabilizer rod, over tightened ’jesus’ bolt on the rotor head, out of balance main rotor or blade tracking. That’s the short list but it’s where I start looking when vibration comes into my models. Hope this helps.
