HelicopterHIROBOOther › Tail Pitch Slider Problem on X-Spec

I am just finishing up my x-spec, and there is significant binding of the tail pitch slider. The interference is at the point where the two pins go into the pitch slider. There are points where it does not bind, but if you spin the tail blades, the slider will turn until it reaches a point where it binds. I have tried filing down the tight spots some, but it still binds and is not smooth.

Has anyone else had this problem? If so, what did you do to fix it? Should I just keep filing?

Thanks,

DK

Mine have a few tight spots also, but it doesn’t “spin” with the blades, there is a bearing between it and the tail rotor shaft. It can “turn”, and does from time to time so the pins are not always wearing on the same spot on the slider ring, but doesn’t need to spin freely as this would just wear out the plastic and the pins.

I know it doesn't spin freely, but it does slowly turn when the tail output shaft turns. When it gets to the spot where it binds, it stops turning and just stays at that point. I'm afraid that the binding will cause damage to my tail servo.

Oh, different than mine, mine is very slight, nothing that would affect the servo. I just checked all of mine and they turn with the tail shaft until the seam in the plastic forming mold hits the pins, and then stay there. I noticed if I give tail pitch input while turning it, the pins jump past the seam. Have about 50+ flights one, about 30+ ea. on the other two, and no problems. If yours are so tight, as to drag down the servo, I would say you have a bad slider ring.

DKflyer,

If you are uncomfortable with the slider, just let me know and I will send you another.

Is the entire slider binding when you move the tail pitch slider at this point? I can see how it could. There does need to be some movement for free sliding action.

Yes, when the pins bind in the pitch plate, the entire slider becomes very tight. It will still slide, but only with a lot of force. I sent you a PM. Thanks for the help!! Super Jeff to the rescue again!
