Re: Torque tube or belt So we are a bit off topic from the vibration issue but I am curious why your throttle HAS to be set at 100% for 2,3,4,5? Now back to the tail vibe. Im thinking your gain might be a bit too high also. Back it off to 70%. When its flying around its constantly making changes to hold true. When you hover its hunting for center very rapidly. So I would ensure the belt is the right one. Then adjust tail and gains again. This is all assuming the tail did NOT contact the ground. |

Re: Torque tube or belt Throttle is set at 100% in position 2,3,4 and 5 with three cells it has to be that way. Never tried to look for idle up on my Futaba 6EX maybe I should check it out,one more switch to mess with. |

Re: Torque tube or belt So adjust your throttle so there is no change and adjust pitch curve to suit your needs. I like 80%-85% throttle at half stick. So when I switch to Idle up mode there is no change because my Idle up mode on throttle curve is also 80 or 85...the same. |

Re: Torque tube or belt I believe the belt is at fault. I don't do idle up or stunt mode 3D or stunt flying is not for me. I fly scale so my pitch and throttle are controlled as one. My throttle hold is set at 0, so when I have it in throttle hold no accidents happen. |

Re: Torque tube or belt Why is there a change in rpm? If in stunt more or idle up mode there should be very little rpm change. I have about 4 used tail gears with the shaft that dont look bent but they are. Not even a straight edge will notice it but the heli will. Replace it and see what happends. P.S. reading back to your first post. I would bet its the wrong belt if the vibration showed up out of nowhere. |

Re: Torque tube or belt Humming type vibration? I have no idea ... it's only guesses till you see it. I would start checking bearings (I guess) lol Cheers |

Re: Torque tube or belt Not tail wag, but a humming type of vibration. My gyro is a Futaba 240 set at 75% gain. The tail wag when it happens is from a drop in RPM I even took some 30 size tail paddles cut , shaped and balanced them to fit so I could have more tail surface. It works well 95% of the time it's only in those panic times you will see a tail wag. |

Well that's weird then ... Ben you say vibration ... do you mean a fast tail wag? like really fast? What gyro are you running in your 500? What's your gain set at? Too much gain will make that beast wag like mad. |

Re: Torque tube or belt I have both and ya, all my 500 and larger have the tails grounded. Since I tend to fly scale sometimes it depends on the raised tail conversion. |
