Hi. What kind of muffler is the one that is for sale at desertaircraft.com for the DA-50R? Is it a Pitts muffler? I want to buy a DA-50 for a Greatplanes Pitts Special and a pitts muffler would look great.

I have never had a gas engine before, only glow. So, how different are gas engines from glow engines? Are they more difficult to tune?

Thanks,
Paul
