Doing my Homework for Twin Mamba Monster flux.

Correct. If you are trying to run high speed runs, making 1 or 2 passes at a time, then these motors can take the abuse at the RPM limit and even over the limit.

Keep in mind Nic Case ran a 1521/1Y on 12s powered by a Phoenix HV110 in his world record run. That was also a single pass, not on or off road bashing.

Any continuous usage, I would recommend staying around the 40-45k rpm MAX.

I would go for the ICE HV-160 if you can. The added amperage and the data logging abilities are quite nice.
