Mkay... got the 4465 motor and 150a ESC installed. Pictures later when my colleagues have left the lab
For now I only have pictures of the worn parts.
The spur gear wasnt uber tight when I made the 1st test run. 44.000rpm will do that to a spur gear in 1½ minute!
After swapping the gear and tightening the slipper fully... the hex shape of the wheel stopped being hex shaped... its round now... time to play with epoxy!!
