Just my opinion, but I think you need to find a slightly heavier built model for even that little engine. This type model is built very, extremely light, for flying, I don't think it would hold up to the stress of flying with that engine mounted. My best suggestion is to look in the 1/2 A forums, and Sig has Herr kits for that size engine. I know there are others, but I gravitate to the larger models. Good luck!
