Yeah, that is a pretty good source. Personally, I have a Great Planes Giant Stik flying for years now with a 50cc twin I built, and it does great. Before I put the 50cc twin on it, I flew it for about a year with a Poulan 42cc on it. Other than those two options, if you want to build a kit, here is another source: http://www.amr-rc.com/products-brand...assembled/amr/

Good luck with your project whatever you decide,
