Trex 700n CNC gears

[Arwel]

I have put the CNC gears in my two 700n helis and having a couple of problems with them. On one heli, the main gear moves up and down about 0.5mm and the other heli the main gear is slightly warped.

Anybody else have this problem?

Thanks Arwel.

You need too shim the main shaft and also make sure the gear is fitted too the OWB assembly correctly...
Had the same things happen with mine.....
