Pilots demanding more speed and power from their motors should look at E-flite's Power 25 BL Outrunner Motor, 1250Kv. Delivering more power than the 870Kv Power 25 (and at higher RPM's), it was designed specifically for the NMPRA's EF1 electric pylon racing class.
The 1250Kv Power 25 BL motor was created for for high-power airplanes weighing 3- to 5.5-pounds (1.4- to 2.5-kilograms) or 15-sized high-speed electric Formula One racers weighing up to 4 pounds (1.8 kilograms).
Features
Ideal for airplanes requiring up to 850 watts of input power
Equivalent to a 25-size glow engine for high-power airplanes weighing 3- to 5.5-pounds (1.4- to 2.5-kilograms) or 15-sized high-speed electric Formula One racers weighing up to 4 pounds (1.8 kilograms)
Includes mount, prop adapter and mounting hardware
External rotor design; the shaft can easily be reversed for alternative motor installations
High-torque, direct-drive alternative to inrunner brushless motors
Quiet, lightweight operation
High-quality construction with ball bearings and hardened 5mm steel shaft
