My main thing with low kv is the less restrictive gearing, especially with these bigger 5mm shafts. I might not be able to buy 4 pinions (i use only mikes) at 15.00 or so apiece, the lower kv allows me to settle for something not necessarily right but i won't burn it down. I plan to try something, I have a 2250 lehner 10t motor (1184kv) I plan to put this in a 8T on 5s for starters, i only have a quark 125 that has a chance to run this beast right now. In my twinforce, center diffed (51 tooth mod-1) with 1/8 buggy gearing the motor can pull a 19 tooth pinion, I figure with truggy diffs, i should be able to do the same easily on 5s and eventually 6s
Another thing, I have a bad habit of taking a path less followed. if someone recommends something, I have gone another route, not to insult them, but that's the established route, I look for different options. I guess it comes from my slotcar days, People wanted rpm's, I wanted torque
