Ben,

The 15T doesn't affect ''Total motor speed'' you can see the RPM is the same with 15T and 18T.

About completing 20 minutes, gear as low as possible. If 15T is as low as you can get and the speed is to much try lowering throttle travel. This will also reduce topspeed / A draw if I'm not mistaking.

Another option would be to get a 1520 (1600kv) in there. Still very efficient but not as thick (so smaller pinion might be possible) and heavy as the 1717.

Hopefully you can complete the 20 minutes, it's a long time :)
