Finding an engine for your aircraft is easy, but getting an affordable engine with such high power is next to impossible! The specially designed crankcase makes sure fuel is equally distributed to both cylinders. It also optimizes power, reduces vibration, and increases durability. The GP123 is a great choice for the Mamba 120!
