One way bearing problem...

[Naxxx]

Hi
I have a little problem.
For me it's the firs Heli, i'm mounting an heli for the first time.
ESC is not already installed, no batteries, only mechanical parts.
When I rotate main rotor counter-clockwise main gear is free.
When I rotate it clockwise main gear is blocked with the rotor.
It seems that one way bearing is mounted in wrong way...
It is possible???
And if it is, What can I do???
:confused:

Check if the maingear is mounted correctly.
See the manual.
Otherwise, turnover the oneway. I think it is possible, but I have never heard of it beiing assembled at the factory the wrong way.

Maingear mounted correctly...

Is your pinion thightly pressed against you main-gear ?
There should be a certain resistance but not impossible to turn.

[Naxxx]

Yes... pinion is ok...
Gear seems working well (as my friend's Hely already mounted) but in wrong direction...

I think I have to pull out one way bearing and turn it in the opposite way...

This is really weird, its the first time I hear of a one way bearing installed the wrong way. Did you buy this heli used or brand new. Try to contact the person that sold it to you....

Could you take a few pictures or short video - seems like something obvious is happening here.

I swear I've had a OWB installed backwards, but I think it was me that did it! :rotf

The bearing was reversed...

Press and extractor; job done in 5 min.

My friend can continue his build..

:thumbup:

The bearing was reversed... This will make your friend feel better - I just got my new kit and the OWB is also backwards. I replaced a number of these, so I know its very easy.

Someone needs to reach out to the factory and find the guy who is installing them upside down. :rotf

And pretty fast too, :thumbdown: that's a real "nono"
