I don't think my truck can get it to the field, but it might fly my truck to the field. I like it.

Thanks Rick, It's a been a long time ago now but I dug up some of the old stats. There's also a few photo's on an old webpage. Paper used was sometimes called "fish and chip" paper - wet the paper and allow to drip, Place paper on a flat non-absorbent surface and paint on the water-thinned wood glue and then place each piece of paper carefully onto sanded foam. If covering wings do both surfaces and dry in the shade to prevent warping as the paper shrinks by at least 10% on drying.

Span 294cm (9.6ft), Length 264cm (8.6ft), Weight 6kg (13.2lb),
power: 20xGP3300 NiMh, Axi 4130/16, 16x8 ApCe, CC Phoenix 60 ESC, 'only' 750W
Construction: paper & thinned wood glue over polystyrene foam.

Following your Osprey build with interest.
