Yes, Canopus XS235 or G-CPDA is alive and well.
However there are no current plans to restore her to full airworthy condition for the previously mentioned reasons.
Recently, because of the rarity of 112v DC, we had a devil of a job to source a replacement GPU but have now got a Vernon Rolls Royce petrol one. Initially rotating an Avon engine on this system needs around 900 amps of current.
PS If anyone out there has got any spare Comet 4C nose wheel steering arm bolts (that have to be taken in and out for towing) I would be glad to hear from you.
