Designed for 480 brushed or brushless motors (diameter:28mm) with 3.175 mm (1/8”) output shaft. The rugged plastic housing fits industry-standard 10x10mm stick mounts, so that the gearbox can easily upgrade GWS models, and a variety of other models using the stick mounting system. The 3mm output shaft is well hardened, and won't bend in the common nose-over landing. The shaft is supported by twin ball bearings for top efficiency at high rpm. The gearbox frame is especially rugged: made from very hard, resilient plastic, it insures that pinion and spur gear stay perfectly aligned, and is forgiving in a crash.
