The compact, lightweight gearbox drive consists of the high-torque A30-M and our highly efficient 6.7:1 planetary gearbox. This makes the use of larger more efficient and quieter propellers possible. Propellers up to 18 inches can be driven by this power dwarf.
For use this only 157g light engine in the classes F3B, F3J and F5J, but of course can also be used in similar models and scale gliders. The takeoff weight is usually between 2.0 and 3.0 kg.
