The BX-120V3-2 has been developed from the BX-100-2 by replacing the steel cylinders sleeves with Nickel-Silicon plating on the original aluminium cylinders. This enlarged the bore and has resulted in an increased capacity and, of course, more power with less weight.
The BX-120V3-2 is without a doubt the flat twin for glider towing up to 20 kilos in weight and for aerobatic models. Even a small silencer makes the BX-120V3-2 an absolutely whispering power unit. With the optional brushless electric starter you have a power unit that leaves nothing more to wish for.
Hans Kolm developed the BX-120V3-2 especially for competition glider towing, he tested the engine in a series of models. The result is an extraordinarily reliable engine for your valuable model.
