I doubt you won't have much feedback on it here,
so far I just found soldering post a little too small to solder wire on it.
There is not much info about this motor mostly because it's not roar legal, and tekin stuff are mostly aim toward Racers, Many racers still relie on the "seen on the track" instead of adds and hype of RC forum to buy there next RC stuff. At least It seem to work for top level driver here in France
