Those were likely the H49 compound which is very soft.

EVTV and Netgain are testing/using the H60 which is much harder.

Any (brushed) motor that is run in at low rpm may have a build-up of brush dust that should be cleared before high amp/volt use.

It can't take as much current for as long as the -11, but it still puts out a higher peak power (at least one documented excursion to 500hp on a chassis dyno).

Tesseract, could you please share the link/documentation for the 500 HP on the dyno for the 11HV?

Took me a while to find it as it was from a thread started by CroDriver on his BMW "Bi-Moto" project (which ended up being a uni-moto, but that's another sad story altogether):

The graph of his dyno run (made by our programmer, Qer) is in post #394 and some relevant, some not so relevant, discussion continues on the next few pages.

That is some mighty impressive peak power!

Greater than 100% efficiency though? Was that issue ever resolved?

Thank you for taking the time to look that up for me. Mucho appreciado!
