PROFI .8cc (.049cid) F1J,C/L, F/F Competiton Engine

Easy handling and great power output. I run mine on untimed crankcase pressure and once the needle setting was dialed in, I’ve had quite a few one flip starts. I fly mine in an RC sport speed model (small composite electric pylon racer) and it was recently clocked at 164 mph with a 4x4.5 CF prop. SIG Champion 10% fuel works well so far.
