Trevor,
Thanks for the note. I think you will be able to make a canopy from the method you mention. You can get very good glass cloth from Fibretech at Lancing with the resin also. I have recently made some parts for my 1/4 scale longeze using the blue foam and balsa method and then making a mould from artist modelling plaster of paris, it worked well and is very light and strong . However the cost of resin and cloth could be expensive for making one part . However it will come in handy for making other parts such as cowlings which I have produced with this technique. Not much to it just make
