Its just the little kit from great planes.

Saito 100 up front turning a APC 15x6 at 9400rpm. I tried to build it light and managed to get the plane without covering to 5lbs. 8oz. and don't ask me how

Only weight added was 2 oz to the left wingtip for lateral balance.
You're right about the elevators. I'll probably extend them after I get used to the plane, but for now, they'll do.
Dunno about wing loading. How could I find this out?
