Am using the motor in my 6s 7hv setup due to the high kV... have more than 1000 flights on the motor...

It's a 24n8p multi strand Wye termination motor, it's a single turn if am not mistaken (maybe 2).

I won't suggest using it for 12s due to high kv, otherwise you'll need a lower pinion count for a reasonable headspeed, which may cause gear meshing issue.
