What's a good ballpark average wing area for a 1/2A boost glider

[shockie]

The title says it all. 20-30 sq in? for wing area ? TIA

Dr.Gregorek says 2x10 for 20 in squared.

That's in the ballpark. Most 1/2A competition glider designs appear to fall within the 16 sq in. to 24 sq. in. range.

Thanks Rktman.
I went back and reviewed every 1/2A BG and RG design since 1968....
I'm going with 25 Sq in

I think the modern S4A birds are running in the 40-60 sq. in. range, but they are incredibly light and use scissor-flop deployment. I would need to get my hands on one to tell you how light, but easily less than 20 g. See the link for information.

Good call. Scissor-flop designs have incredibly long, high-aspect-ratio wings and usually a carbon fiber fuselage.
