The reason you have no experience with Glow four strokes is because they don,t work as well in that venue, I rest my case. There are plenty of examples in airplanes where they are not normally used agine for the same reasons.

Now you wanna talk sound, yes I know it is not politically correct prefer something other and I understand you dig the sound of that twin with a pair of fourstrokes but for me this airplane has the 'nicest noise I have ever heard' and those are two strokes.
