Thanks for the info W8ye,

I have ordered covering: Profilm (Oracover?) transparent orange (54 g/m2) for the leading edges and underside, with ProLite (Oralight?) transparent white (36 g/m2) for the trailing edges and topside. The full product spec is here:

I ran up the OS FS-30S engine today on the bench with a 10x5 prop - I reckon I might get 18-20 mins duration from a 6 oz tank. Started first time and sounds sweet at idle or full throttle. It's my first I/C engine and was not quite as messy as I expected - just a little fuel dribbling out of the carburettor and greasy exhaust.Will post video link later.
