I started out with 2 stroke engines, got out of the hobby for a while and when I got back in I went to a 4 stroke engine just to try something different. I've since bought a gas engine and I'm learning about it, so far so good. I like the electrics except I miss the sound and I think it's kinda funny to see speaker kits so the airplane makes noise. I guess it depends on the application and what you like to do. My Ultra Sport is great with my old OS 61. To me fast planes need a screaming 2 stroke. I like my (retrainer) Ultra Stick with my Saito 100. It reliable and has no problem at all pulling the airplane. It's not too fast but some days you just don't want to be fast. My new 36 gasser I'm learning about, so far I'm liking it. It swings a big scale looking prop and you don't need too much for equipment to go fly. Gas, radio airplane and go fly for 45 minutes on a tank of fuel that you'd be refilling in 15 minutes on a nitro engine. As bad as gas prices are, gas is cheap for RC. Try buying a gallon of 15% for $4. I don't like the smell though, I can't really bring the aircraft into the house to work on it without stinking the place up. Electric is something I'd consider if it was cheap. If I could buy an engine cheap and 5 or so lipo's for $10 a piece and fly a .60 size plane, I'd get into it. but $200+ for a big pack is out of my price range right now and I don't want 10 - 15 minutes of flight time and 30 - 45 minutes of charge time maybe more for the big packs, I don't really know.
