MadScientist, what powers the A-10 that you have on your avatar? When I'm ready to move up in this hobby, I want an A-10. Is it jet or ducted fan? How fast?

I was wondering of designing an A-10 on autocad with a single regular glow 2 strk. engine mounted b/n two turbines inside the 2 ducts by some type of chain. Imagine the piston shaft connected with the 2 cam shafts in a car engine. The piston shaft is like the engine and the two cam shafts are like the two turbines. Well, it's just a concept of mine. I haven't even started flying yet. I'm very much a newbie. I'm imagining again. Sorry.
