600-UL700 Class

Performance 600s and (ultra-) light 700s share a sweet spot: enough headroom for real power, without the weight that calls for a bigger motor. The Tengu 4230EC Eclipse is our motor for exactly this spot — light, efficient, and happy anywhere from a hard-flown 600 to an ultralight 700. (A regular 700 that isn't flown super-hard 3D? The 4230EC handles that too.)
