Thanks Kris! That is the first time I've heard it broken down like that. Oh, the mount is not separate, hmmm. I can't wait but like I said, what airframe? What would you put this engine on? A special and very light engine should deserve an equal platform. I'm not sure if there is an ARF I'd put it on. Thanks Jeff, your right if they would all agree on or there would become a standard on how the weights should be posted then we would know. I'm just finishing a 3D kit right now and would not mind starting on the 55X project. !~)
