RE: Second plane?
The Mini Ultra Stick will be perfect for your level if you are wanting to stay with park flyers. It's designed to be a second plane to let you develop your skills more. They are great in the wind and can be extremely maneuverable if you turn up the throws. After a couple of flights, you'll be saying the stick is easier to fly than the Super Cub was. Get an experienced pilot to take it up the first time and get everything trimmed out correctly. If you want to move up to bigger planes, a .40 or .60 size stick from pretty much anybody who makes one will do nicely.
