Hi I agree the racing machines are of a different order. I only do scale sail, but at the moment I am working on a 27 inch loa hull I bought on Gumtree, well actually I have 2 very similar hulls They look identical but have some small variations in beam, both carved out of a single piece of wood a bit like a half size Marblehead from the late 50's.
They are really well made (and I am b****y fussy), only needed a bit of cleaning up. It was a bargain 2 beautiful hulls for £30 the pair, I had to go to Salisbury to pick them up but well worth the journey.
I have, like yesterday, just set one of them up with the sails from an Aeronaut Bella. Fortunately the hulls are hollowed out and now I shall fit the RC ready to get out and sail asap.
I will take some photos and work out how to post them.
