Brushless motors for 550-600 Class Helicopters Brushless motors best suited power source for electric helicopters debut. O.S. brushless motors first released in 2011 have been well supported by many modelers worldwide due to high performance as well as high quality and reliability. Now O.S. has decided to release motors for helicopter models in response to the needs of the times i.e. quite and clean. The first two models are for 550-650 class helicopters. Best performance required for brushless motor for helicopter use has been thoroughly pursued based on expertise built up with the brushless motors for airplanes. Successful development of friction reduced major parts achieves higher maximum efficiency and optimized KV values minimize the heat generation. Also, 45mm dia. enables to be installed in almost all the existing models of this class without modifications. OMH-4535-1260 has 1260 KV value and is suitable for sport and 3D flight with 550~600 class model and 6 cell batteries. OMH-4535-560 has 560 KV value and is capable of performing serious 3D maneuvers with 600-650 class model and 12 cell batteries. You may choose a model according to your flight style. Brilliant O.S. Blue of outer can is a symbol of high performance and high quality.
