Bidproduct motors = better built feigaos. They are cheaper, and use a one-piece magnet vs the segmented magnets inside feigaos, but they give pretty much the same performance and temps/efficiency.

For 6s A123 like I run (= ~5s lipo), I'd say the 1900kv option would be best or there abouts, but the 2200kv MMM motor will be more powerful and efficient for sure, just gear down a touch to compensate for the higher kv/motor rpms.
