Main shaft has a wobble to it

[rudderman]

Ok my main shaft has a wobble to it. But there is no vibration when i power up.Is this normal to have some wobble on the main shaft ?

have you recently crashed? one of the things that seem to take a hit in a crash is the main shaft. i do not believe the wobble is normal (but i am new too). i recently had to replace the main shaft (and feathering shaft as well). i checked very closely after the replacement and did not see any wobble. the main shaft comes in a packet of three and feathering shafts come in a packet of 4 (that should tell you something :wink: ). go ahead and replace; if that didn't take care of the wobble, then all is not lost. you will eventually need the main shafts anyway.

Oops, wrong forum. i was thinking of the trex on the packaging qty. i don't know how many main / feathering shafts come in a packet for the eflite models. i have a cp pro but miraculously have not bent a main shaft yet.

1 main shaft with gear attached in a package.

Are you sure the main shaft is wobbling or the head not quite right. Hard to believe that a bent mainshaft wouldn't give you vibration.

Well i found the problem with the wobble i think.The shaft that connects the blade grips was bent and so was the main shaft. So i tapped on the main shaft and got the bend out and the piece that connects the blade grips.Just to see if that would help.It did so i will be getting the parts tomorrow.First time ever working on the cp pro its much easier than i thought :D

Microheli makes stronger main shafts for the CP pro along with an autorotation gear. They also make a stronger feathering shaft.
