my tail boom is slipping no matter how tight i make the bolts so i was thinking to put electrical tape around it and then reinsert re tighten is this the best way? i haven't really tackled it because of work but i want to fly this weekend so i need to fix it please post all the ways with pics if you got em of fixing a slipping tail boom this is on a logo 500 but im sure a slipping tail boom is the same on any heli ... its slipping left/right not in/out although im sure it would slip in/out as well

If you don't care about having to replace another part (not sure how it works on your model), put a little thin CA on the boom where it goes into the clamp. If possible, a very small sheet metal screw (make sure it won't hit the belt/tube) will do wonders too.

I also used scotch tape on my Rex 450. I also took the the blocks and sanded a little off the insides to make the "circle" a little tighter.

I just thought of something, go to the auto parts and get some "fine" grade valve grinding compound. It is a paste with fine grit mixed in it. Spread this in a thin layer between the blocks and tube and it should hold. I remembered this because I did that one time on my windshield wipers on a car. The blades stripped out and was just sitting there on the windshield. It worked until I was able to buy new arms.

Packing tape
Clear packing tape will work as well.

You have the right idea. Any tape can be made to work. You're just trying to take up space and get the boom tight.

I cut a 1/2" piece of Flex-o-grit fine sandpaper and slip it in on both sides. Grips like crazy.

I use small screw thru both the front and tail mount, just long enough to go through the tube, but not hit the TT/Belt.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

this is what I used to do with my Century stuff. Works really well.

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

I just drill a small hole in the 500 tail boom holder on the part exposed outside of the frames. Then I thread a small set screw in. Works like a charm.

I had that same issue on one of my birds awhile back. I think the best way of fixing it was to use a piece of electrical tape. That way you can easily remove it if necessary instead of CA.

It's a complex, costly, glow powered anti-gravity machine!

For those of you using a screw, do you have any problems adjusting the belt from summer to winter? It would seem like the screw would want to go in the same hole since its just a small movement.

I would suggest that pinning or screwing the tail boom in place is a really good idea with a tube driven tail and a *bad* idea for a belt driven tail - no way to adjust the belt tension.

Scotch tape for me as well.

The way I have mine setup is that the set screw (same kind you'd use for a pinion or tail hub) does not pierce all the way throught the boom. To adjust belt tension I just loosen up the set screw, then go about setting belt tension as you would on an unmodified heli. When the proper tension is achieved I tighten up the set screw.

CAUTION...
If you are flying a Mikado and you put a screw in the hole that's already there, be very careful NOT to pierce the boom. It is very easy to screw it down too far and go right through the boom.

It leaves very sharp boom material on the inside of the boom. After a couple of flight your belt WILL wear and snap...go ahead, ask me how I know ;^)

Just trying to save you some unnecessary stress.

My belt driven Razor has a separate belt tension adjustment. Does not rely on moving the boom.

If in doubt lean it out . We don't do this to save money, we save money to do this
