I have one, and I don't think I could have learned on it. I bought the Multiplex power set and it's a little under powered and heavy, to use as a trainer. Paint would make it even heavier. Don't paint it, nobody's going to like it for its looks anyway.

Better yet, get a plane you can learn on. Like the SoarStar. Or one of those SlowSticks the other guys talk about. The Multiplex TwinStar is really not suited for a park where there are people around. Even if you get a more powerful power set, it'll be faster, but not lighter - that's why I don't think you'll like it for learning. I like to train people on planes that will fly slow, and the TwinStar isn't really capable of slow stable flight.

Good luck
