SainSmart feeds & speeds

High Country Tools groups the SainSmart in its Hobby ultralight class (source), so ChipLoad uses that class's published settings.

We haven't verified spindle or rigidity specs for the SainSmart from a primary source yet, so we don't list any. Set your spindle's real max RPM in the calculator.
