Cliff,
Welcome to the forum.
Regarding the prop vortices, as I said in my previous post, I have never seen them visible in the air before, and it was interesting to hear that you couldn’t see them from the cockpit.
And thanks for the info on the power settings/speeds for your Buchon display. It’s always interesting to get information on these kind of things (well, if you are interested in them that is!), and compare power settings/entry speeds to those used etc. in the other Warbirds during a typical aerobatic display.
I was surprised at only 5lbs of boost (I say only!), as I thought it would have been around +6 or + 7lbs & 2650/2700 RPM which is usually what the early to mid Mark Spitfires seem to use for a display.
Mind you, having said that, I remember reading an article about the former RAC Buchon (an aircraft which you are of course familiar with), and I recall it being described as a ‘Pocket Rocket’, and Taff Smith mentioning that during a display with the OFMC P-51 & Spitfire, both of their pilots kept telling him to ‘Pull back’ the power so they could keep up!
Whilst I know a lot of people dislike the looks of the Buchon, I don’t think you can argue about it’s performance.
Cheers
Paul
