FWIW, I use a 1512 2d on 4s and it works fine. Even geared up on 46/16, the motor is perfectly fine and stays cool (even for me). I tried it momentarily on 6s and it still is fine, if too fast to control!

The Neus seem to not mind higher rpms. If you run a high rpm, just gear down a bit to keep things controllable. As long as you stay under 50k you should be perfectly fine IMO.

In my Ultra GTP project, I plan to run a theoretical 62k rpm on a 1515 (but the rpms won't get that high because of wind drag).
