Marwen, I'll bet you could build that same plane like it was a stick and tissue micro-electric job, maybe RTF at 1/3 or 1/2 of a pound......and all the handling quirks go away. I think if you build just about anything light enough, you can make it work. Dick Sarpolus published a C/L canard in .35 size that flew well by all accounts. It wasn't a bad looking plane, either.
I wonder if he ever tried to build a 1/2A version?
