Still have no idea as to the mfg. sorry.

balance point? OK, Do you see where the leading edge sheeting stops at the wing spar? If you balance it there or JUST barely in front of that it should fly. I would recommend an experienced pilot take it up the first time though. It might be tricky. Once it flies you can adjust the balance to suit you. Just don't go too far aft.

Looks like it will be a fairly good flyer if that helps any.

Can you tell by the construction if it's a kit or ARF? I'm thinking ARF due to the striping.
