Title: How to straighten bent main shafts or aluminium tail booms Post by: gauravag on February 13, 2010, 01:54:25 PM Guys,
While i am away from home, i was wondering if there was any known/easy way to straighten bent main shafts and dented tail booms. My last heli crash left me with one, so i wanted to know if we can re-use it :salute:, or if it goes to junk :thumbsdown: Even a slightly bent shaft poses a risk of vibration, and the tail boom dent affects the drive belt running, so they are critical parts. :help: Title: Re: How to straighten bent main shafts or aluminium tail booms Post by: anwar on February 13, 2010, 03:14:57 PM Like you guessed if they are bent enough, they cannot be fixed properly.
There is a bit of hope if you can apply heat in a localized manner, but the end results are often counter-productive. For main shafts, people have tried hitting them with rubber mallets, and you get lucky sometimes. Dents on the tail boom are ok, but bents are trouble.

because a damaged heli costs a hell lot to repair compared to planes !

The bend is so light thats its invisible to note to the common eye but can be detected when rolled on a glass. Shafts are goners, dont want to risk straighting them, but need to find out a way to straighten flybar/Boom. Probably inserting/hitting a rod inside the tail boom that is exactly the inner dia of the boom should solve the problem {:)}. But the problem is finding a Rod exactly of that dia. ;D :P
