RE: 4 Stroke vs. 2 Stroke Maintenance
It's not that much different. A valve adjustment from time to time (not everyday), and a good bit of oil at the end of the flying session and you're in good shape.
Skip the oil, and you can join in the masses posting things like "my bearings are all rusty". <GGGG>
4Cs are fun. Enjoy yours.
