Hi,
ESM (Kondor models I think) also make a Spacewalker, 80" span I think, The pics of it look pretty good too.

The Seagull Spacewalker is a 40 size plane, flies beautifully, very stable and is a well built plane. Mine needs considerable right rudder on the take off roll but other than that is a faultless, honest airplane.

If you want a big plane that is very stable, fun to fly and will do general aerobatics you can't go past the Pacific aeromodels "Gee Bee". Very well made, goes together well and is a treat to fly. This plane just does not stall, just slowly sinks.

Hope this helps,
Rod.
