    Certainly for the 50th anniversary there was quite a major event at the Derwent Reservoir so I imagine at least something will happen there this year.

    Airfields always come first due to I believe Prescott who classified them as brownfield sites. I suppose there could be some argument that an ex-RAF airfield with a full complement of runways, hangars and technical buildings is brownfield but no way for a small grass airfield.

    That would be a good idea. IIRC the golf course actually belongs to the council too and the airfield doesn’t.

    I don’t believe it was the finish on the sleeves that was the major problem, it was distortion. All sorts of materials were tried and it was only when Bristol were instructed to reveal their methods the problem was solved. Bristol sleeves were machined from centrifugal castings which were very stable. When Napier switched to the same the reliability was transformed.
    I was told some years ago that Sabre sleeves were made by GKN in Chesterfield and have no reason to doubt it.

    Yes, I had one of those too. Aluminium monocoque fuselage and cardboard wings with, I think, plastic ribs. I don’t remember it not flying so I guess it did.

    There are even a couple on a well known auction site.

    I was 7 and it was either a Douglas B-66 or a Grumman Cougar, they followed in quick succession. I can’t remember which came first or what make they were but in my defence it was 53 years ago. After that I started on the Airfix range at 2/- apiece as Moggy said.

    First rubber Keil Kraft Pixie, took me weeks to save up for that. First (successful) power Frog profile scale Hurricane.

    Yes, his forays out to the town park each lunchtime are the talk of Stamford.

    That would explain why assorted waterfowl (don’t know anything about birds) look nervous every time I go to Stamford.

    There’s an old thread on WIX about it including some input from the landowner but it hasn’t been updated for 3 years.

    Use something better than WD40, it’s not a penetrating oil although a bit better than nothing.

    There was a thread a couple of years ago about the merits of various potions

    On a much lighter note – long before

    I fully agree with the call for practical useful buildings rather than “landmark” vanity projects designed to win awards.

    Speaking of which…
    How about the fuel system that allowed the engine to cut out under neg Gs?

    Hardly fuel system, it’s a float carburettor. That’s what they do under negative G.

    Having said that, I’m surprised that nobody seems to have thought it might be a problem in combat. Possibly a relic of the Air Ministry attack plans where they thought fighters would be just attacking bombers in immaculate peacetime type formations.

    Knights of the Air: The Life and Times of the Extraordinary Pioneers Who First Built British Aeroplanes – Peter King.

    It covers Roe, de Havilland, Handley Page, the Short brothers and most of the rest of the UK pioneers up to the time they retired, died, got taken over or whatever.

    A great book and very well written.

    I’ve lent it to two or three people who’ve all tracked down copies for themselves.

    In your view would it be an idea to contact the manufactures if they are still kicking around?

    DH Engines went via Bristol-Siddeley to Rolls-Royce.

    It’s possible the Rolls-Royce Heritage Trust inherited the archives but I don’t know if they did or not. Could be worth tryig them.

    I took this photo last week. It has barely changed over the years.

    Pic snipped

    The building looks the same – but it wasn’t grey in the ’80s. Brick?

    A rather grey day at Salisbury Hall, I seem to recall

    It was a very grey day, all my photos came out a really strange colour presumably due to automatic colour balancing in processing.

    I had a full frame of RS712 on a slow pass with as I remember wheels flaps all down – I hadn’t wound the camera on.

    I bought a motor drive the following week…
