RE: First Jet
I would suggest a P-70,(of course there are many other brands and thrust ranges suitable) . my suggestion is based in that this turbine idle thrust actually helps you to land this plane at the same time that it has "punch" to throw your roo at impressive speeds. it also gives you a extra minute of flight compared to the average mid-sized turbine fuel consumption on a 2 liter bottle.
