Overview

Designed to deliver clean and quiet power equivalent to or surpassing the power of a 90-size 2-stroke glow engine for sport and scale airplanes weighing 8 to 13 pounds (3.6 to 5.9 kg), 3D airplanes up to 10 pounds (4.5 kg), or models requiring up to 1800 watts of power. It will provide excellent 3D performance for the Hangar 9 Frenzy 100 ARF, ShowTime 4D 90 ARF, Funtana X 100 ARF and other similar class models. The Power 90 also provides great power and performance for the Seagull Ultimate Bi-Plane 90 ARFs.

Tech Notes:

Maximum operating temperature: 220 degrees Fahrenheit.

Adequate cooling is required for all motor operation at maximum current levels.

Maximum burst current duration is 15 seconds. Adequate time between maximum burst intervals is required.
