RE: Katan mini setup.
This is funny, I've been trying to get a set-up for my mini Edge and TP 1320's. It was suggested to go with a 450 outrunner to stay away from gear boxes or go with a 400 inrunner, ( I'm going with the Himaxx 2025-4200kv) and a Cobri gear box. I guess Cobri is the best and wont strip out like as easily.
Cheers
