E-Flite Power 25 Outrunner 870kV w/3.5mm Gold Connectors Brushless Motor - EFLM4025A

The E-flite Power 25 Brushless Outrunner Motor (EFLM4025A) is an 870kV electric motor designed as a direct replacement for 25-size glow engines in sport and scale RC aircraft. It delivers up to 600 watts of power and suits airplanes weighing 3 to 5.5 lb (1.4 to 2.5 kg), making it a strong choice for electric conversions or new builds in that class. It also works well for 15-size 3D airplanes up to 3.5 lb (1.6 kg). Known compatible models include the Sig Kadet LT-25, Sig Frazer, Lanier Extra 3.25, Global Tequila Sunrise 25, and Great Planes Taylorcraft 20.
