KONTRONIK

Great Planes is now the exclusive U.S. distributor for Kontronik high-end electric flight products. With brushless motors, ESCs and gear drives that match the performance of glow engines and the added simplicity of plug-and-play, Kontronik is taking a lead in the electric flight revolution. All Kontronik Brushless ESCs can be used with "sensored" and "sensorless" motors and include: soft-start, anti-drift, temperature and current overload protection, a current-limiting circuit, autoprogramming mode for quick and easy setup and rpm control to govern the main rotor speed on a model helicopter.

The "Smile" Brushless ESCs are competitively priced and are designed for easy operation. The programmable Jazz Brushless ESCs have more features for the advanced pilot. All Kontronik brushless motors include machine-pressed winds, durable steel cans and 89-percent maximum efficiency. The 25 to 45A Fun 400 motors are ideal for small, fast airplanes, such as Speed 400 racers and ducted-fan models. The more powerful Fun 480 runs in the 30 to 55A range, and the Fun 500 and Fun 600 motors are great for F5B class models and larger scale models that require a power system that can operate in the 45 to 65A range. All the Kontronik products are sold separately and in sets for easy set up and installation.
