For 6s I woulod say the 1518 would be a good choice. I did run the 1515 2200kv motor in a lst on 5s and it did very well. But if you plan to do alot of stop and start bashing a lower kv motor that has more torque will be the way to go. I did prefer the neu 1521 1y on 6s in the lst vs the cc 2200kv motor on 5s.

I have a 1520 but have yet to use it. Also have another 1521 neu so I plan to see if one is better than the other.
