<< I have never agreed that any engine designed for surface vehicles is all that safe in an aircraft but for those who just cannot afford to use an aircraft engine like continental, or Lycoming an out board motor would be the best alternative. >> FWIW... Rotax makes a very good line of 2-stroke engines designed for aircraft use. Most of the ultralights use their engines. My wife and I flew our Challenger II from western SD to OSH last year... nary a burp out of the Rotax 503. That being said, most of us would prefer to use a 4-stroke but with weight being a big consideration, we go with the 2-strokes. I have also surprised myself at how comfortable I've become flying ahead of my Rotax (it's a pusher) over the past 3 years and 362 hours. :-) Jim Hayward Rapid City, SD
