I'm around 75% done building the SIG 1/5 scale cub and I am using a OS 46AX to power it. Seeing it together and the overall size has me a little worried now. It does recommend 40 to 46 2 stroke, just seems like its a tad on the large side for this engine. I try to fly scale and am not a hot dogger by any means. My question is will this be sufficient or am i setting myself up for a problem going with this engine.
