Parkflyers
Crashem,
There are about six Slow Sticks at our club. I only have one flight on them, but it flew exactly like my Megatech Merlin (everyone seems to dislike it but me).
Haven't flown the Soarstar, but the LHS highly recommended it, mostly for durability. So Peter's comment is a bit surprising, though I don't doubt it.
Willtrevt,
You're going to find yourself in a Catch-22. If you get a plane (like the Slow Stick) that you can reasonably expect to teach yourself to fly, it will probably soon become boring. If you get one that's not going to be boring fairly soon, your probably not going to be able to teach yourself.
If you really insist on no club/no instructor, your best bet is to progress through several different airplanes.
Good luck (if it were me I'd find a club)
