Tail Boom Repair technique

While replacing and repairing the other two heli's I found a common tool that works very well to repair a bent tail boom.

I use a long Phillips screw driver & rubber mallet helps to tap out creases while the screw driver is in the tube.

I also used this super long screw driver that I found useful.

Insert the shaft of the screw driver down the tail boom (Note: see the damage).

While holding on to the tail boom, hammer/force the screwdriver down the tube to push out the dents.

I was able to get it pretty straight, as you can see.

This has worked well enough to keep me in the air till new parts get here Very Happy

Hammer & screwdriver kmkstar - that's my style too when nothing else works.

A 450 boom is approx 10.5 - 11mm ID and is difficult to find an interference fit to do similar.
But a 10mm long masonry drill can be used to drive down through to remove worst dents. Careful wriggling can also pop creases / dents etc.
Best to have a nice smooth rounded end so the dent is 'eased' out ...

Now if anyone has access to a Music repair shop - then get to know the guy who straightens / removes dents in trumpets / horns etc. as they use the method of steel balls connected in a string. Various sizes depending on where the dent betc. is.
