Kontronik Pyro 750-45L Competition Brushless Motor Long Shaft

Special Order: Process 3 – 5 business days

The PYRO 750 continues the heritage of the KONTRONIK PREMIUM LINE. It is compact, extremely powerful, and has a continuous power of 4.5 kW. 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 shafts with four sizes. The internal shaft is 10 mm, allowing the use of 10 mm bearings for longer life, and an external shaft of 6 or 8 mm that allows it to easily fit most helicopters. This little trick makes the PYRO 750 the ideal choice for all pilots who like to have more, but can’t install the PYRO 800 because of reasons of space.
