I have the Lanier CAP (Kit Version) with a Brison 3.2. It weighs in less than 16 lbs with 1275 sq in of wing area.
Excellent flight characteristics. I almost have to force it into a sping because it will not drop a wing

There is a thread here in the Giant Aircraft forum on how to lighten the Kit. Basically you will have to add lightening holes all over and replace the foam in the turtledeck with balsa sheeting.

Cheers & Happy landings.
