No worries, you can buy 6mm bore pinions, or you can just do like 99% of other guys did in your situation and grind the shaft down; all you need is padded vice and a metal file / dremel and some digital calipers. Stick the motor in a bag and poke the shaft through it to keep out the filings, then work back & forth along the shaft ( ahem.. ) and keep checking until your 5mm bore pinions fit snuggly. Either that, or sell your $70 motor for a large profit on a heli/ plane forum...
SORRY guys, unfortunately these motors were made with a 6mm shaft (that's why they were off to the side in the warehouse.)
If anyone is unhappy with the fact that they got a 6mm shaft, please let me know. We will give a full refund to anyone who wants to return the motor.
(P.S. -- I didn't know about the sale until after the motors were gone ... and I would have suggested charging $150, and not $80 )
Thanx!

For 70 bucks I'll deal with the 6mm shaft.
I am just happy to be getting one since I already came up with a need for it. I wasn't sure then some planning and ideas just all came together and the motor will fit the bill perfectly.
