Re: Helicopter Shake If you want a decent throttle curve setting let me know. My radio is in the truck ready for tomorrow! Finally a nice fly day! |

Re: Helicopter Shake my 600 has a wobble when it spools up. Are you hovering? If you are learning to fly you might have your throttle curve set wrong. Like me when I started I was using throttle to fly. When your curve is set right you should be a about 80% RMP at mid stick. (correct me if I'm wrong) While you are flying you should not notice a RPM change unless you throttle right down. Where I'm going with this is if the motor is changing speed it might be spooling up and down and getting the same wobble as you do when you first idle up while still on the ground. My slight wobble disappears before I lift off. |

Re: Helicopter Shake Sometimes lubing the belt with silicon lube takes away vibration. Rubber can get sticky and if the tracking isn't perfect it will ride up on the edge of the pulleys. |

Re: Helicopter Shake Belt driven tail? If the belt is loose, you'll see shake when the teeth on either side of the belt meet.... |

Re: Helicopter Shake What kind of shake? Has the heli been set up properly? Is this symptom new or has it been there from the start? Has the heli been boinked? All of these would help point us towards a solution. At this point your lack of specifics as to the type of shaking and our lack of knowledge of the condition of the machine mean we are limited to making educated guesses and requests for more information. If the shake you are describing is a rotation around the main axis it also might be worth pulling the flybar rod to check for straightness. The same can be said of the feathering shaft and dampers, but in that case the vibration would likely be constant and affect blade tracking. On that note improper paddle incidence or loose or damaged linkages can all affect how the rotor system performs under different load and/or flight conditions. If the shake is a vertical nodding action the rotor RPM may also be borderline too low. |

Re: Helicopter Shake the blades should be just tight enough that if you hold the heli with the nose pointed at the ground and the blades out to the sides and give it a good shake the blades should fall downwards. based on your description the blades are indeed too tight. |
