Don't worry too much about maintenance on a 4-stroke. I've been flying them for years without any problems. I have everything from an OS .26 to a Saito 300 twin. If you use good 4-stroke fuel and don't run them lean they can be as easy to care for as a 2-stroke. In all the years I've been flying 4-stokes (always Saito or OS) I have only had to adjust the valves on 1 and that is really easy to do.
