One thing i didn't do before i started this project was to measure the lenth of the Ryobi,,,,DOH!,,hehe,,,,But it looks like it will work out pretty close if you use the two inch motor mount from Pete.If you are building the fuse and use a two inch mount move the firwall back 1/2 an inch,,,course the 3 inch will be 1 1/2 inches.The Fiberglass Specialties cowl works pretty good,watch the flywheel though,that is VERY tight.You will have to cut a new firewall due to the fact of the slope of the nose and build up to the original outline with balsa around the engine to match the cowl.Lot easier to just forget the cowl,build according to the plan,use a two inch mount and you are not that much farther out than the propline of a G-38.Besides the cowls are 35 smakers!!!Also make sure you have enough room for the fuel tank,things are pretty close up front on this plane.There is however a nice size gap in the leading edge of the wing,the back part of the tank has to fit in there.That saves the day.

Oh yeah,,,,,bout painting the cylinder heads,,i used Plastic Kote engine enamel,worked out great.I am going to give Dupli Colors purple anodized engine paint a try on the next Ryobi.I am taking pictures and will post the progress as soon as i can.But one thing ,,,,SHEESH!!!!!,,,,,,,30 bucks for the landing gear for this plane plus shipping?My Ryobi is brand new and i only paid 20 bucks for it.and i got a 2 fer one deal on the planes on Ebay,,,,,two Ultra Hots for 60 bucks,CALL ME CHEAP!!LOL!!!!
