Thanks for all the replies about the canopy. I'll see what I can come up with.

I've been very conscientious about hooking up servos this time, and I soldered in extensions rather than using ready-made plug in ones, so there should be no threat from oil. Another thing I think I might do is to fuel-proof the exposed wood around the nose and the firewall - it doesn't seem to have any kind of protection at the moment.(?)
