Is my main shaft bent!

[Tosh]

Thats just it it dosn't vibrate the top resonates giving you the impression that the shafts bent.

Sounds like every other raptor to me. Just fly it, you`re ok.

With every thing switched on move the swash as high up the main shaft as you can. Now slowly rotate the blades. lf swash rocks the shaft is bent. Main shafts that are slightly bent can usually be easily straightened.

Hi Tosh

I'm having the same issue with my 600. How would one straighten a main shaft that's slightly bent?

I've just ordered a couple from Fast Lad but, if the one I have can be fixed, that would be good.

Oh, BTW, I've not crashed my 600 so if it is bent, it was bent out of the bag.

Cheers.

You cant fix them.

Just keep your fingers crossed that royal mail deliver it before they go on strike.

Let's hope so...

I haven't got a glass table, therefore I always test for bent mainshafts (when not obvious !), by sticking them in an electric drill and spinning them up, it's usually pretty apparent when they are bent. I always flip them over and test from both ends. Works for me

Works on feathering spindles as well, but these are even easier to test by removing the blades and blade bolts, sticking a driver on one blade grip retaining bolt, and while turning the driver (and the feathering spindles its attached to), watch the other grip, if it moves up and down, the shaft is bent.

You mean YOU cant fix them?

Spill the beans Tosh! How's it done?

I think a good way to check is to take the head off completely and give it a little throttle - not fast though.

Not a good idea with a nitro IMHO, no load on the engine.

He get's his engine loading from chopping up his mates with the tail rotor, so it's OK

True

Simplest way to check is remove and roll it on a piece of glass or mirror.

My wife came in the room while I was browsing this thread "Is my main shaft ben...!" she gave me a strange look and left the room without speaking. LOL
