Little bit of horn tooting here.
Either find someone with a copy of "Radio Modeller" for February 1995, or you can buy the plan from Radio Control Modeler in the US - it's their plan number 1243. It's my old "SquErt" design and will still do as many aerobatics as your list, but for peanuts in construction costs.
It was built when all I could buy was a 7.2V 400 motor and flew on 7 x 600 "AA" sized nicads, suggesting that it would really go on a 6V and 7 or 8 AE cells. Would do a Cuban Eight on the above at a time when most 400 electrics rated 'climbing' as tricky stuff.
Value - costs peanuts in wood, you assess building costs of local labour
. Performance - kept me happy, the designer had high standards
Looks - that I can't help, its a little boxy, but has a high degree of form following function.
Really needs a rudder, but that's easy to fix. I even have copies of the plan (paper only, it was pre-computer and CAD days). Heck, there were two at my funfly this year!
