I currently have a GP Big Stik 60 that I have used as my trainer. While I am still learning, I am also considering my next plane to build this winter.

I am interested in some type of low-wing or mid-wing sport plane. I want to be able to learn aerobatics with it, but don't want something too agressive or difficult to handle. This will be my primary plane, so I want something fun and provide all around good flying.

I have read a bit and am currently considering the following:

WM Chipmunk 90S
WM Super Sports 60
GP Shoestring
Lanier Stinger 60

Please provide your thoughts and suggestions.

I would like to stay in 60 size (with a ST 75 engine) and definately want an ARF. Some day I would like a warbird (P-47 or P-51) but I am concerned that this is not a good next step.
