These controllers are unmatched in their price class, and even
outside their price class! Up to 40% more FETs than similarly-rated
ESC from other makers, and those FET are higher-quality fast-gate
type. That means that you can push the ESC harder without fear
- up to 40% over their rated continuous current shorttime - and
performance is higher at all throttle settings due to low intenal
resistance. With an inexpensive programming card, you can choose
settings for battery type (Lipo/NiCd-NiMH), startup, braking,
frequency, timing. Just about everything. The ESC automatically
and accurately set cell count for lithium packs 2S to 4S
