| Post subject: | Wobbling(Solved) |
Hello everyone A curiosity I have an Oxy 3 with esc HW 60 v4 Platinium , 4100 kv Eox Motor ,main blade 285 mm and pinion 11 teeth and lipo 4s.i am using the Governor of the spirit which is fantastic.I noticed a small problem, he did it two time, in practice I have set 3,200 rpms in the governor and 80% flat curves on the radio. I can start hovering at 2,500 rpms, but I noticed that I hover before the 3,200 rmps, between 2,600 and 2,900 rpms the blades have a slight wobbling, they seem to unbalanced looklike flutter, as soon as it reaches 3,200 rpms everything disappears. but this problem only makes it between 2600-3000 rpms when I'm already in hovering the problem does not seem to me to be worrying, because if I do take off directly at 3,200 rpms it seems that there is not wobbling. I thought, could it be that i set the spool up in the governor of unit in a very slow way? sorry for my english, but i use the translator.I hope I was clear Thanks to all |

Hello, some models might start to oscillate quickly in aileron axis due to imbalance. This can happen only in certain headspeed. When you are out of this range it is usually good and is not a problem then. You can solve it with a different Head dampeners or possibly main blades or even making skids heavier. If problem appear only at the beginning then maybe blades are not fully unfolded. Try to make main blade holders more loose |

Hi I loosened the blades, and I set the spool up in slow, before it was very slow, and I gave him another 300 rpms to the head at 3,500, rpms the problem seems to have disappeared. Thanks for the answer
