RE: Tissue and PVA for covering foam cores?
Man, When a friend and i discovered packing tape covering, was it a revelation!!
The coloured stuff looks good enough too me, and it is light and strong. My first norvel .061 plane was a tapey, four hs80`s a 4cell 270mah nicad pack and a windser6/3.. unlimited vertical! And it was fast to make.
Its just such good stuff.
p.s i found some here in japan!! Very cool stuff with the colour in the plastic film(I think) and the adhesive is white, so should give a good, consistant red rather that the pink that can sometimes result. Dunno how it is for fuel/oilproofness yet though!
