Ok I've narrowed it down to four:

1) Boxer 60 (scratch built)
2) Tracer 60 (almost same design as boxer, scratch built)
3) Tiger 60 (kit)
4) Birdi Chaos (kit)

For me I see two distinct differences between 1, 2 and 3, 4. Effort to build and wing design.

1,2 are scratch built and have tapered LE.
3,4 are kits and have constant cords wings.

I have a Satio 80 (or I may buy a MVVS 90 2-stroke) and have standard JR equipment to put in it.

Which is the best to learn on? I know there could be differences in opinions but that's what I need to hear.
