Draco: Chmura's number was misprinted in Pilot. It is in fact 01736 786 032. I happen to know he's just sold the 12C that the article was about, but has others.
I'm not so sure about the unsupercharged 12C being the most underpowered machine in Christendom. I've flown it with three fat blokes in and it's well up to the task. Rattles like a bitch and you risk bird strikes up the chuff, but otherwise OK.
