bent inner shaft...?

[heyjack8]

ok newbi here crashed a few times already thank god for spare blades...my cx 2 flys pretty good ....however at slow speed watching the top of the aluminum inner shaft it seems to whobble a bit could it be bent slightly and still fly pretty good..?
or do they all whobble a bit at a slow speed...i hate to replace it since it still flys and hovers fairly well....sill have to make small inputs on radio on hover but over all not bad....is it possible to bend inner shaft with out bending outer shaft...i wouldnt think so but im new.....

If it flies fine then i see no reason to repair it. May be a bad bearing too, the one at the very top right below the upper headblock is made of plastic and can wear down. As long as it flies well it should be ok.

Yes, you can bend the inner shaft and not the outer shaft... This happened to me when I managed to crash it upside down into a tile floor (who put that wall there anyway?).

Just know that excessive vibrations can do bad things to gears, bearings, etc. Also, a bent shaft does make the heli unstable, requiring those constant corrections you mentioned.

A new inner shaft is only about $5... replace it and get back to stable flight!

Mine wobble all the time. I replace the inner shaft 3 times and the outer shaft 2 times and still no change. I even played with the set screws to see if that was a factor of the outer shaft but still no change. My bird flies just fine so I ignore it. Me being a perfectionists I like to reduce as much wobble as I can. Remember, you will have a little wobble at low speeds. This is normal in any heli. There is so much going on, im surprised that the darn things don't just blow up.
My Blade 400 wobbles at low rpm but when it speeds up the vibration starts to cancel out from other vibrations. She is rock solid at idle up speeds. I also notice the noise goes away and she runs very silent.

Good luck and have fun...

gotcha man whobble is at low speed runs smooth when she powers up....thanks man
