e-Minicopter Joker > Freewheel Bearing size?

I was changing my freewheel bearing on my MJ-2 and the replacement bearing , Part Number 746 is shown as having a 12mm ID.

The bearing that was in my beltwheel(748) as well as my shaft,(747), is not 12mm.
It is 10mm.

I looked through the price list to see if I could find a 10mm freewheel bearing, but I didn't see one listed.

Does anyone have a clue to this 10mm size freewheel bearing comes from?

Am I going to have to buy a complete new shaft assembly at 12mm size just to replace this bearing?

Thanks, Steve

FXAeromodels doesn't show it on their website.

So will the manual be updated? So is #445 the correct part number? A replacement?

Sure enough FXA has #746 though... mmmm...

#445 is an older part and was replaced thru 746 in 2005. The 10 mm bearing has always worked well in electrics (Joker/Maxi-Joker), but in the Acrobat .91 glow the plastic cages in the bearings broke sometimes from the motor vibrations and then the bearing has locked on the shaft. So we have replaced it thru the 12 mm bearing #746 for all types. But in an electric you can use the old one, too.

Thanks to Joe Howard I was received a complete 10mm shaft assembly on Friday. It felt as if my bearing had some dirt in it causing it to bind up two times on me that I experienced, so I considered cleaning or replacing the bearings on the shaft as well. Since Joe had the assembly ready to go that solved the problem there.

The size difference concerned me, but I was thinking that the electric motor was smooth enough that the 10mm could handle the power well enough as it was working without incident. Thanks for confirming that for me Gerd.

Just have to makes some notes in my parts list
