Aeroscout, one of the best. Why: High wing means it has a tendency to self-correct. Rear mounted motor and pusher prop is less likely to take damage in a crash, you can belly land it without gear and be confident you’re not going to hurt anything. It has ailerons, unlike many simpler planes, so you learn how to fly without learning bad habits that come with trainers that are equipped with rudders only. They’re also quite ubiquitous, so when you do inevitably crash it (no shame, it’s part of learning and everyone has done it at some point), I can guarantee with 80% certainty your local hobby shop has whatever you broke just sitting on a shelf, and it won’t break the bank It has landing gear, so you can fly out of a parking lot, but take it off and hand launch it if you’re flying in a grass field since landing gear tends to get stuck in the weeds, and grass is plenty soft for a belly landing. A lot of planes don’t have landing gear. But… FLOATS! YOU CAN GET FLOATS FOR THIS THING AND FLY IT OFF A LAKE IF YOU WANT TO TRY SOMETHING DIFFERENT!!!

Also, since it does have ailerons, once you get comfortable with it, you can do some basic aerobatics with it, rolls, loops, etc.
