If you can keep temp low and under control then I do not see any problems with driving any scale model. But there is one thing which you need to consider, with every today's speed controller (with SO/SOIC) only one side has good heatsink, that means that only these FET's can be used in calculation for rated power dissipation (at elevated temp) and use derating factor as well. So if your quark has enough FET's to dissipated power of losses associated with 2230 motor at your working temp, then you should be Ok, otherwise that's would be your limiting factor. |
Yes, that's what I mean. It should keep all FET's very cool... the top FET's will have copper heatspreader to case, and the bottom FET's will be directly attached to case, it should work great!
I really am excited to see what comes out of your esc's for performance. What is the bigger problem then? -Getting the heat away from the FET's? -Or the number of FET's handling the power?
430A current capability, that's impressive!
