Default Problem with aluminum tail slider..

First off, thanks for taking some time...

I purchased an aluminum tail slider assembly a while back after the original plastic slider eventually wore itself to bits. But now after about 30 flights I am noticing a problem. the two metal "pegs" are digging into and gouging the aluminum cylindrical slider. what is causing this? what sort of lube should be applied to this area, if any?

thanks again guys. I figure for a 15$ part it would last a bit longer.

I have the same setup on the tail, it looks like you need to back the two little locating screws off a little ....it sounds like they are too tight and binding .... they are only meant to sit in the groove of the slider and it should spin freely, i use silicon greese on mine. and it's been no problem.

As far as I can see, the slider "Pegs" or locators as you called them are not adjustable. they are pressed into the aluminum pivot / servo arm assembly. the original plastic assembly had threaded screws.

unfortunately, the locating screws on the "hopup" aluminum tail rotor pitch level is not adjustable (correct me if I'm wrong).

Yea .... My Bad, On closer inspection they don't look like they are adjustable.... apparently it's all in the assembly, if you over tighten on one side more than the other then it can case binding.

Default Hello

This kind of ware has troubled me since I first started flying. Although I have not encountered
anything like you are describing, I'm always on the lookout for problems like this in my own helicopter.

Is the inner bearing seized or bound in some way?
Even if the pins are a little tight. I would think the bearing would spin and the pins would not eat away the outer guide like that.

I'd replace the assembly and if necessary dress the pins on the new unit with a small file
so there is no binding at all. a small amount of silicone may be in order as well.

The inner bearing spins freely with no binding.. And the "race" or outer section that has formed some deep grooves also spins freely, I just don't get it, ovbiously when there is any pitch added to the tail, the locator pins are just gouging their race/guide. , the same thing happened with the plastic unit, thus why I upgraded to the aluminum version.

Are your tail grips smooth when they rotate? looks like maybe the pitch control slider is encountering some resistance. Also check your endpoints to make sure you don't have any servo bind. Remove the pitch control lever and cycle the control slider by hand and see how it feels

Default Hello again

I purchased a set of carbon fiber blades the other day. When I asked about CF tail rotor blades I was advised to stay with plastic tail rotor blades as they flex and do not tend to over load the tail rotor assembly. I see your not flying stock tail rotor blades.

Any chance this could be where the problem lies?
