RE: supercharger
frost....this is the first time i have disagreed with what you are saying... my 2 stroke dirtbike and my friends snowmobiles engines operate the exact same way as 2 stroke r/c car engines except for they have spark plugs and not glow plugs. all 2 stroke engines need the incoming fuel charge to push out the exhaust gasses, therefore on all 2 strokes the intake and exhaust ports will allways be open at the same time for a brief moment. I am not saying that the super charger will work on an r/c car engine, i believe that is just a sales gimmick and bling factor. But i do know for a fact that they do work on snowmobiles.
