Default Tail boom keeps slipping

I presume that the 2x12 screw that goes into the boom cover holds the boom in place. Problem is that the boom holder is either stripped or the screw doesnt create enough tension on the boom. Thus the boom keeps slipping. Any thoughts?

Don't hate me, but there is no problem putting packing tape around the boom, then tightening it up. Worked millions of times on many belt helis.

Another option would be to get a lynx boom clamp and press it up against the boom block after you tension the belt.

This, did it on one of mine. Stock boom clamp works ok too

On my other x3, just pinned the boom fore and aft

I have the X3L which doesn't use a boom clamp and tail boom supports, just a screw to tighten to the frame via the boom clamp set which is in the frame.

With the tape, are you suggesting wrapping the end that goes into the frame to make it a tighter fit?

I use poor "man's fiberglass". Put some CA on the end of the boom and then smear it around with a tissue. Let it dry and voila, the boom won't slip ever again.

slide this LX0849 onto the boom and then adjust the boom to where you need it and insert the 2x12 screw to hold the boom from "twisting' in the boom block..(you can use a little CA on the screw, use it like loc-tite to hold the screw and give it some bite).

Then slide the boom clamp tight against the boom block and tighten the clamping screw...Done.

I used a gaui x3 plastic boom clamp and it works OK.

In my experience, unless you assembled things incorrectly in the first place, for example, over or under torquing the tail box fasteners, this shouldn't be happening. The tolerances on Gaui stuff are fine and work well.
