View Full Version : Bent Flybar
Harry Spillett

Hello people,
I have recently rebuilt my Raptor 30 rotor head with the addition of the
Quick UK flybar, carrier and head button, however I noticed that after it
was all back together and being balanced that I had managed to put a slight
bend in the new flybar while refitting the paddles. (Doh!)
How concerned about this should I be? is it acceptable to gently flex it so
that it runs true, will it sort itself out in flight or should I bin it and
fit a new one?
Incidentally I was rather hoping that the Quick flybar would be stiffer than
the original TT part, one of the reasons I changed it was because I was
worried about bending it!
you know what they say "if it aint broke......"
Thanks
Harry

If it is not a large bent then you can straighten it.
Remove it and roll it on a glass plate or a smooth kitchen bench. Mark where
the maximum bend is with a felt pen then gently straighten it using whatever
method you prefer.
Keep doing it until you have less then 0.5 mm bend which is more then good
enough.
Now reinstall it CAREFULLY :-)

There is a magic trick to straightening out slight bends in flybars.
Take it out of the heli and get a piece of wood. Put the wood in the vice
and drill a small hole through it so the fly bar will slide through easily.
Put the flybar in the chuck of an electric drill and poke it through the
hole.
Bend the flybar a little while the drill is running and draw the flybar in
and out of the hole. In seconds it will be dead straight again.

Tweak it back to "eyeball" straight Harry.

Don't worry about bending it in flight, just when you pick the heli up with
it:-)

Persackerly. Don't mend it, just unbend it (or in my case "uncoil" it:-)

I never put you down as a musical instrument repair specialist Peter.
