Yesterday i finished my Outrunner Conversion. I am using the following electrics:
KD36-8XL Outrunner
Modded Quark Competition 80 (Case removed, I've added a 1000µf 35v cap and a heatsink)
Zippy 2000mah 4S Lipo
I have replaced the two chassis braces by a long M4 threaded rod and a carbon fiber tube. I'm using Traxxas Victory rear tires on Jato rear rims. It's working great, cogging isn't existing. Here you can see a small vid:

I hope you like it!
