Ok so first off let me just say this is all PRELIMINARY as in brainstorming, just having a hotel day off thinking about this stuff. I am fascinated by champs and j3 cubs. With that said let's get down to details. What kind of costs would I be looking at nowadays to own one of the two aircraft mentioned? What kind of yearly upkeep would I be looking at? I want something that is extremely affordable yet allows me to have some fun flying. Ideally I'd want an RV3/4/8 but that is just outside of my price range. I just want something I can fly completely VFR and sputter around 500AGL having some fun. Of course, this is all preliminary.
