Summary

The Power 46 is designed to provide clean and peaceful power for .40 to 46-size sport and scale aircrafts weighing 4 to 7 pounds (1.8–3.2 kg), 25- to 40-size 3D aircrafts approximately 5 pounds (2.2 kg), or designs requiring approximately 925 watts of power. It’s a specifically excellent match for Hangar 9 .40-size fitness instructors like the Alpha .40 (HAN2450), Arrow .40 (HAN2625) and warbirds like the T-34 Coach 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).
