Alright, time to get some life in this again. Stumbled on the Basher BSR Rally / Team C GT8LE-RA's 42T spur gears on Hobbyking, and thought they might work as a nice cheap and lightweight pinion/spur combo.
Having seen Lizard's disappointing results with the TP5840 and the resulting philosophizing about how a theoretical max efficient ERPM would translate into lower preferred RPMs for 6-poles (aka, I might have chosen the wrong kv again :D), I got rid of the my cool-looking, but not so smart DIY CF motor spacer, so the motor-mount is mounted directly onto chassis for better heat transfer. Gap between motor and chassis is filled with thermal pad, which also nicely helps cushioning vibrations. As this will only be used on-road, I won't seal up the venting holes as I did with my TP4070.
Still need to add some o-rings to the center-dogbone dirve-cups, as there's a bit too much vibration in those still, but getting close to driving again.
