Thanks for the replies guys. The reason I'm curious about these engines is simply because I'm thinking it would be considerable cheaper to buy a used weed wacker and put the motor in a plane. I'm more into planes like Yaks and edges,but I dont really have anything in mind at the moment. I figured If I could get an engine coverted I'd buy the plane to fit the motor. I'd be looking for something in the 26 - 50cc size. The only plane I might be looking for an engine for is one that I just finished last night,but problem with it is that its a 77" yak with a smaller 1.20 2-stroke engine in that I had sitting on the shelf. And this engine will likely be too underpowered for this plane,so If I can find a good cheap gas engine in it....that would be cool. Another reason I want one of these gas engines is just to play with,so thats another reason the size wont matter. I just have no idea what I'd be getting into,and if it would even really be cheaper in the long run. I've heard rumors that these engine I much heavier then the "made for rc" engines,and for that reason arent practical. I also dont know a thing about what needs to be removed from them,nor what needs to be added to them(carbs,ignitions,exhausts,flywheels,prop hubs,etc). I also have no clue what to look for in a used engine as far as brands,or the simple mechanical setup of them. I've got tons of glow engines,but never got into gas. I just think it would be fun to try this if its going to save alot of money. I've done some searching,but sometimes its good just to have one on one coversations to get the specific answers you need. Thanks again guys!


I just need to start with very basic info I guess.....
