550-590 Class Helicopter Motors

One class, one clear recommendation: the Tengu 4030EC Eclipse (completely redesigned around our new 40mm custom stator) is the motor for your 550 to 590 size helicopter — from the popular 580s, which take blades up to 610mm and the 4030EC obliges, to SAB's upcoming 590. (If your 580 leans heavy or your flying leans hard 3D, the Tengu 4230EC from the class above fits too.)
