This engine is particularly suited to the rigours of 3D Fun Fly competition flying, where the limitations of model size and engine capacity are controlling factors. It is no coincidence that most of the competitors in Fun Fly at the Nationals choose the Irvine 39 as their powerplant. These pilots demand power, torque and throttle response and the 39 delivers this in style.
From the precision cast crankcase, through the true ABC piston liner to the CNC machined, Jetsream carburettor, the Irvine 39 shouts quality.
