    Brilliant, I had a go in one when in the ATC a long long time ago, the parachute was a mans size on an 11 year old, I dread to thing of the damage to vital parts if I had to jump . The pilot said if we have to get out I will say jump three times if you don`t we both die!!!
    We survived , I still remember that flight, maybe I will try to find another opportunity.
    Thanks for the video

    My friend had an Auster, about 1970, he got me to take him out to the airport so he could shift it to his paddock strip, on the way back to town he 'Buzzed' me, I'll never forget that sound. I was with him one day when we landed on his paddock strip in a cross wind, put the wind up me when I was looking out my side window at the strip we were landing on. Ted from down under.

I was told that the Provosts for Prince Charles were special in that absolutely no concessions for minor production errors were allowed , and the engines were brand new, as opposed to “reconditioned”. I spent 2 years in EMUAS on the Chipmunk , which tail wheel experience was a great advantage when 10 years later I obtained my commercial, my first job being on the Dak. I flew with quite a few Kiwis over the years.

    • @VaughnDavisTV
      @VaughnDavisTV  6 месяцев назад +1

      I'm not very knowledgeable on the whole range but believe the Gipsy Major was the heart of it and powered the most aircraft types in its various Marks from 1-10. The Gipsy Queen was a 6-cylinder version that you might find on a Devon/Dove. Main upgrade from the GM 1 to the 10 was more horsepower (130 to 145) and many more accessories. I think all the Tiger Moth version comes with is an oil pump.

      I believe that removal of the cartridge starter and installation or an electric one was part of the standard mods when leaving the RAF?

    Thank you for a nice walk around your engine, I've never been around one of those. The inverted engine puzzles me, the oil must be delivered to the crankshaft, and then what, it just slugs up and down on the backside of the pistons? How is it returned to the oil tank? Anyway, there shouldn't be any rust in there! Beautiful aircraft.

    145HP Gypsy Moth. I've flown one with that engine. It was a Canadian version with the bubble canopy. The English version had the bird cage type canopy, which is the easiest way to spot the two types. A popular engine conversion was putting in the 200hp Ranger, another inline engine. But those are probably scarce now days and the parts for it as well. I thought it was a real docile flying plane. Handled like a Cessna. The plane I owned at the time was a 125hp Globe Swift, which was a bit more demanding and flew a lot better handling-wise. So the Chipmunk was a bit of a disappointment to me.

    • @VaughnDavisTV
      @VaughnDavisTV  6 месяцев назад

      I realised afterwards that I hadn’t mentioned the carb heat. On the right hand side of the engine look for the long spring extending from the firewall towards the carb. It controls a flapper valve inboard of the carb air intake that switches air intake to that flat round thing left of the carb - it’s open towards the engine block to take warmer air through a mesh filter. It isn’t greatly different to normal air, at least when testing on the ground (usually can’t see an RPM drop). The cartridge starters were all removed on demob - all that remains is the exhaust vent on the RH cowl. The two 12V batteries are in a compartment behind the cockpit.

      @@VaughnDavisTV Can you jog my memory on the downwind brake check ? My recollection after 53 years is, on the ground you apply the brake with full rudder, and count the clicks until the brake bites on the rudder pedal. Then apply two more clicks (say 5 in total ). Should you need differential brake on taxi, or take off , then it’s available.
      After take off the brake you fully release the brake to enable full rudder available for say spin recovery. Downwind you reapply the brake for say 5 clicks, so that on landing you have differential brake available to counter swing and a ground loop.

      @@californiadreamin8423 many Chipmunks including mine have had the original Dunlop brakes and wheels replaced with a more modern Cleveland system. Depending on how they’re rigged they often provide a little differential braking even at no clicks. To be honest, flying with either system I just do it by feel and only preset a few clicks for takeoff or landing if the crosswind is approaching limits.

      Not that different. Tiger Moths use one of the Gipsy Major Mk1 variants which produce 130hp vs 145hp for the 10 Mk 2. The Mk 1 is the same basic engine but lacks the fuel pumps, generator, starter and vacuum pump found on the Chipmunk version. Tiger Moth engines also seem to be OK running on Mogas as well as Avgas.
