SpEEdyBL,

Not only we have a few members here and myself, who are running HV, we can back any statement said. We have real world experience and I can't find where the heat is generated to cause the same loss you've mentioned. From what I know (I'm not an engineer) when electronics are subjected to high heat, they become less efficient and that can be seen in any Electronic Component being Active, Passive, Electromechanical and Interconnect. Look at some datasheets of and you will see that a MOSFET will perform better at a cooler temp. then at a higher temp. The only thing that I've seen perform good when heated to a safe high temp is lipos. SpEEdyBL, have you done a HV conversion? If not please do so, but thinking of a speed machine, but a well geared racing set up. BrianG's calculator is a great tool and I use it a lot. Now John knows how a high turn motor acts in producing torque in rock crawling. I would like to see how a high Kv motor does in rock crawling.
