So confused!!!! Okay my fellow heli folks. This is making me scratch my head! I have a Roban 700 size Bell 429. And recently I have experienced a weird issue with my tail rotor. What’s going on is intermittently I am losing my right pitch. At first I thought that it might be binding somehow? But after checking all the linkage and moving it both right to left it is free as can be. Then I checked the radio on monitor function (Spektrum DX7S) and everything looks good. Then the next thing I checked with the receiver battery hooked up I moved the helicopter left to right to see if the Gyro is functioning correctly. And it is. I am running the Spektrum BeastX. So when the heli is in flight occasionally I will lose tail rotor Authority when using the radio trying to move to the right. I also know that it has nothing to do with the radio because all my other helicopters function fine. So now I’m going nuts trying to come to some conclusion as to what the problem may be? Any ideas are welcomed. |

Tim W Another thing that puzzles me is when I had the receiver battery plugged in and was using the radio it would sometimes not respond to right rudder input? But this was very intermittent? So there was no resistance on the tail rotor like there would’ve been if it were in flight. Team Thunder Tiger since 6/2005 to 12/2014 |

Girard Ibanez Is this a new problem?If so and nothing changed perhaps your servo is not holding. Have you tried to apply manual torque to see if the servo is holding?Also, a low rotor head speed and also reduces the tail rotor rpm. You can increase the head speed and see if the problem goes away. If it does and you want the low head speed you might want to increase the tail rotor length or cord. Or change the gear ratio. |

BeltFedBrowning Is the linkage pushing or pulling on the tailrotor bellcrank when turning to the right? |
