Miloh, I said interesting, because I haven't tried the sheeting methods Jack uses in his designs.
My concern would be all that gas right next to all that foam.

A friend had a balsa sheeted Corair. his gas tank leaked. Ate the fuselage to the point that it couldn't be repaired.

having said that, I'm sure that if you seal the tank area with epoxy, you would minimize the danger of that happening.

If I shyed you away from the Devine kit, I didn't mean to, but I feel you should understand what could happen.

Also, I don't think the Bob Holman focke Wulf kits have been mentioned. I'm building on now. It comes with a glass fuselage, foam wings and vacuformed parts. No wood. 80 inch span, G38 or llarger. Looks like it will be in the 20-22 pound range. i'm enjoying it very much and I'm told it will be a good flier.
