A purpose designed and perfected engine for the latest class of .50 class helicopters. This really stunning ABC derivative of the aero version, is what power is all about! This awesome power extends across the whole RPM range so that you can exploit your helicopter’s true performance without worrying about running short of power at an awkward moment. A large and efficient heatsink head will remove that unwanted heat with minimal airflow and the insulated carburettor will maintain precise control at all RPM/load combinations.
