Overview

The Power 46 is designed to deliver clean and quiet power for .40 to 46-size sport and scale airplanes weighing 4 to 7 pounds (1.8–3.2 kg), 25- to 40-size 3D airplanes up to 5 pounds (2.2 kg), or models requiring up to 925 watts of power. It’s an especially good match for Hangar 9 .40-size trainers like the Alpha .40 (HAN2450), Arrow .40 (HAN2625) and warbirds like the T-34 Mentor 40 (HAN2425). Also a great match for sport planes like the Ultra Stick 40 (HAN1675 or HAN1690), Seagull Spacewalker 40 (SEA2050), and smaller sport 3D planes like the Twist 40 (HAN2650).



Hardware is included with the purchase of this motor.
