I would like to use this engine for an R/C airplane if It's possible. Has anyone used this particular engine before? It's a two cycle engine.

Need some pictures to tell. Most anything can be converted, but some are much easier and more worth it than others.

Thanks,

Looks simular to a Ryobi 31cc http://www.ereplacementparts.com/tro...267_27270.html

From what I've read other places it is indeed the Ryobe 31cc engine.

I once contacted MTD about Troy Bilt engines and found out the engines are Ryobi engines,but that Homelite made them for Ryobi.That's why this one resembles the old Ryobi 31cc.I've had the Ryobi,Craftsman and Bolens 31cc trimmers and the engines were the same and all made in the same place for whatever company wanted to put their name on them.I now have a Troy Bilt 25cc 4 cycle TB6040XP that is made for MTD to put into their Troy Bilt trimmers.I sold the 31cc engines to guys that wanted to convert them to airplane or airboat engines,so it can be done. Jag Engines and Carr Precision make the mounts and other items that are needed to convert these engines. www.jagengines.com and www.carrprecision.com

I've seen some newer Ryobi 31cc engines that weren't nearly as easy to convert as they used to be. One of the large castings that used to unbolt, is now all one piece necessitating a bunch of cutting and grinding that we didn't need to do before. Additionally, I have seen Ryobi badged equipment with Homelite 30cc engines in them. I also have a newer yet Ryboi, that is completely different yet. It is side exhaust, side intake, and while it needs a little cutting to convert, it is all easy to do and I believe the engine is going to come out much lighter than the old Ryobi. I am going to convert one of those soon, so I'll report back.

Thanks for the info. I will try to put up a picture of the engine I have. I'm not to good at posting pics though.
