See-saw hub

[Ratjr15]

Anyone have issues with screwing the mixing arms into the see-saw hub? I stripped the 1st 1, and the second's well on its way... Was thinking of CAing the mixing screws, but I'm afraid if I do, it'll get into the bearing.... N e suggestions?

If you do, don't ever plan on taking it off. You'll have to replace everything attached to it if you break a mixing arm. You don't have to crank down on them, they warn you all over the manual not to overtighten things. Maybe you could get away with a longer scew? If not, maybe just get a new see-saw, its a pretty cheap part.

I have the metal mixing arms... i figure, worst case scenario, I do CA it, and something has to come apart.. I can break the see-saw off of the mixing arm (I'd imagine)... Am I correct in thinking this is possible? I don't wanna have to replace the mixing arms...

If you are using the metal mixing arms and the plastic see-saw, and you stripped out the threads in the plastic, I would sugest you just replace the see-saw anyway. I had a crash caused by a stripped thread in plastic when the screw and link ball came out of the swash, even after I CA'd it in.:arggg: Cheaper than the parts you'll break in a crash if that screw comes undone in flight.
It's hard sometimes when screwing into plastic to tell if you have things tight enough, resulting in over-tightening and stripping the screws.:dontknow For what it is worth, and I know some people might disagree, I use blue lock-tite even on plastic. Just a drop on the end of the threads, and wipe it so it is only in the threads, not a drop on the end, and tighten just until it seats. Won't strip, and I don't have to over-tighten to keep from unscrewing.:YeaBaby: Hope this helps.

Threadlock on plastic? Some people will disagree? How about the people that make the threadlock?

This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
Recommending anyone using locktite on plastic is setting them on the road to eventual parts failure.
