I've been flying 2 strokes from my beginning, back in the early 80's... and I love them. Ultra simple, reliable, and only 3 moving parts... you can't beat 'em.

But, I've started playing with a couple of 4 strokes recently as well, and I'm starting to have a little confidence in them and getting to like them too... But there will always be a need for 2 stroke engines in my hangar. They're just too bulletproof.
