I'm building a Genesis 35 with Bob Hunt cores,  52 inch wingspan and so far 8.7 oz. without flaps, I'm thinking that's not bad.

I have two unassembled ARC Vectors which I weighed when they were delivered.

Others who know more about these things than me say that these weights are pretty good.

I hope they help.

For info, from the Brodak website —

Wing Span:      50.5 in.
Plane Length:  42.25 in.
Wing Area:      536 sq. in.
Engine:           .32 to .40

Dwayne, the weights are the individual component weights that I measured from the ARC kits that I bought.

The only info from the Brodak site was the model specs, span, length, wing area, engine.
