Some new way are used here to produce these new outrunner brushless motors. They decided not to do same but better, and the result are incredibly efficient Orbit brushless motors. These motor feature triple bearing assembly and balancing of each element to avoid any move of the rotating cage which would allow loss of efficiency. Highest quality magnet are use in conjunction with the material used in the HP 355, which lead to huge torque and efficiency.

Compared to some other commercial outrunner these motor achieve at least 10-15% better efficiency, which is amazing.

Orbit 25 series are great choice for .40 to .91 to electric conversion
