RE: Extreme Flight Vanquish 2m Build Thread
In general, electric motors are spec'ed for a particular voltage range which we casually refer to as "S." A10S motor would be expected to underperform on 8S unless the mismatch can be overcome with a different prop. If one is going to stick with 8S in the long run (why?), a different motor choice might be considered. When new to large electrics, I always suggest sticking with the recommended set-ups or known equivalents (like the excellent and cost effective Himax 210 kv motor on 10S, for example). Will it be for pattern flying or sport flying?
