| Post subject: | Tail Not holding.. probably mechanic. |
My Triabolo with tri-tail was flying great at 1500hs, whatever I throw, I had it at 10.5* pitch and 10* ele, With a 18T. Have the red tail pulley and 110mm tail blades. Whanted more agresiv to do some maneuvers, so I change it to 13* pitch, and 20T, so I can run at 1770hs. Tail is not holdin on pitch ups the nose turns left and it turns like 90* then return the were it was, and when doing fast stop the tail blow and does not hold... I try playing with the gyro sensitivity but no help.. Should I move the ball link on the tail servo in (close to servo) or out? The only mod I did was change pinion / pitch and HS. |

Please always attach your settings, so we can check if there is everything OK. Unfortunately it rather look like the mechanics is not able to hold the tail at the low head speed and high collective pitch. The only solution might be longer tail blades if your gyro gain is already set as high as possible. Is the head speed constant enough? This can play a role too. |

Also change from HW160 to Scorpion Tribunus... could it be the internal GOV not acting fast enough |

Yes, it could be this too. There might be big differences between governors. |

Some one in HF forum contact me saying he had same problem (same heli and ESC) but with neo and he had to double the collective pre comp, what should i be moving.. here is my 4ds file.

If revomix will help, then the solution is just on the edge. It might work, but you can get into a situation, where the tail will turn about 90-180°. You can of course try it. Alternatively I recommend to try higher Pirouette Consistency - this might work better. But not more than 200. If it is just low mechanical efficiency, longer servo arm might help as well. |
