277091 Kontronik PYRO 750-50L Long Shaft Brushless Motor
The PYRO 750 continues the heritage of the KONTRONIK PREMIUM LINE. It is compact, extremely powerful, and has a power output of 4.5KW. The PYRO 750 surges past the performance of the PYRO 700, approaching the levels previously set by the PYRO 800.
The unique design of the PYRO 750 provides a shaft with two sizes. The internal shaft is 8mm, allowing the use of 8mm bearings for longer life, and an external shaft of 6mm that allows it to easily fit most helicopters.
If you need ultimate power for a 700 class helicopter, look no further as the PYRO 750 is the new powerhouse for the 700 class.
