I am finishing up a new build of a 90SE. I really enjoyed building it and I think its gonna be a great flying heli.

One thing i noticed is that the metal elevator arm is a bit loose on the shaft that it is pinned to. The set screw is tight and it is mostly side play, rather than fore-aft play, but i'd like it to be a bit tighter.

It is loose enuff that i can't imagine loctite really making a difference.

Have others noticed this, and if so, how have you dealt with it?

Use some threadlock on the shaft before putting the arm on that will take out the play

i had mine come out after about 15 flights. This is what i did. I used a large amount of blue locktight on the pin shaft and arm. This tightened it up nicely after it was dry. I also used a longer pin (from tail shaft bevel gear) so i can preflight it better and know that it is there. It has been holding good for about ten months. Hope this helps and keeps a eye on that pin and all the other pins on the heli. The other pins you will just lost the tail that one you lose eveator.

Good luck you will love the heli

Not really worried about the pin so much as the looseness. I'll try some loctite, not optimistic.

Thanks for all the suggestions. I've loctited the shaft, and the pin for good measure, as well as the set screw of course. I'm not gonna touch it tonite, and let it dry. Hopefully that will help a bit with the play. Looking forward to a maiden flight later this week.

I have the same problem with my stock aluminum set up. It is only a matter of time before something happens to the pin that keeps the arm locked to the elevator mechanism. This is a poor design. I am contemplating replacing the metal with a plastic unit off of the "standard." I will keep the metal "A" arms if they fit.

Any thoughts?
