Dan,
140 litres an hour? Peanuts! Another DH product I've flown a couple of times (briefly) is like seven Doves in formation - the Vampire T11
British Imperial fittings. That takes me back to my motorcycle days - three sets of spanners (BSW, BSF and BA) and oil stained shoes!
I love all DH types. I have flown in more DH types than any other manufacturer and have stick time in quite a few of them. My first-ever flight was a joyride in a Dragon Rapide. I flew in a Devon from Shawbury to Aldergrove and back in 1968 and coincidentally in a Queen's Flight Heron on the same route the previous week. That caused some consternation at Aldergrove when a bright red Heron appeared out of the clouds and the Station Commander scrambled to meet us. He was not impressed when a bunch of scruffy (by RAF standards) UAS students in flying suits came down the steps!
