    I wish it was only kids and youngsters..
    I remember one refuelling of the Tiger particularly interesting: we organized a small fly-in at our airfield, there were lots of ppl and despite we placed red&white tapes to delimit the “keep-off” areas, we had a couple of “infiltrates” hanging around.
    I was standing on top of the cowl refuelling with a fuel tank, I turned my sight for a second and there it was, that silly sod looking at what I was doing smoking his cigarette.. sometimes ppl stupidity is beyond human comprehnsion..

    eheheheh we have the long exhaust, so our fuselage won’t be that oily 😉

    U know, radials are as aerodynamic as a brickwall, they burn oil like anything, they’re loud and u have no visibility but… well they’re awesome! 🙂
    Have been working with Gipsy Majors for several years, really nice but they need so many attentions!

    yeah I kinda thought it was something like that mate 😀
    there was even the AB, that is the submunition bomb, the germans had so much fantasy for weapons.. Think about the Fritz-X!

    anyway, flying at midnight would be really cool, but here we have the firecrackers tradition and it would look like a Dambusters Raid 😉

    in reply to: Inverted V Engines,,, WHY ???? #1360492

    Please correct me where I go wrong here – but I have in my mind the piece of info that because of carburetion on the Spitfire/Hurrican vs fuel injection on the 109 the English pilots had to do the half roll to dive whereas the German pilots could simply push the stick forward into a dive – saving precious seconds at difficult moments.

    Makes me wonder/query whether there is/was any cause and effect between inverting the vee and fuel injection. And of course the related question, could carburettors be fitted to an inverted vee?

    In other words were these two different approaches deliberate design principles related to fuel injection vs carburettion – and inter alia related to fighter design principles?

    u can surely put a carburettor to an inverted V engine, but if u have injection stick to it 😉
    As per the negative Gs… The issue was solved on the MkV with the anti-g carburettor (dont ask me how it worked though, I just know it was there..).
    Good point even about the exhaust glare, this surely was another positive point for the inverted V solution!

    the bf109 prototype was designed to be used with the Junkers Jumo 210 engine, an inverted V 12 cylinders engine. Unfortunately the engine wasnt ready for the prototype so the Bf109 0 was flown with a Rolls Royce Kestrel engine. Anyway the main reason seemed to be the visibility, but if i remember correctly the DB engineers decided to mantain this layout even because they monitored a better burning performance of the combustion chamber in the inverted position, with a better response on the throttle. This configuration even allowed to install two MGs on the top cowling. Last but not least the propeller shaft was really near to the roll axis, I dont know how much bad this was for a fighter plane.

    It LOOKS like a Spitfire, so what the hell else are you going to call it?! 😡

    call it whatever u wanna call it, but not Spitfire.. how about MiniSpit or something? :rolleyes:

    I wouldnt be 100% but i think u can, if u seal the tube with yr lips and keep blowing..
    We have the same troubles here: in the ITAF museum they change a lot of formation lights every year, and in several occasion they found ppl inside airplanes taking pics (that can be done, but with a supervisor and a previous written request) or even taking gauges out of the panel!
    The ejection seat sounds like an urban legend to me too: a military ground chief once told me it happened in the air force to a guy doing mantainance on a F-104. He incidentally pulled the ejection strap and was shot out of the plane. He witnessed the thing happening and he’s a really trusted guy. Anyway I thought there were arming or safety pins on ejection seats too, and btw u need a certain amount of force to do it, dunno if a kid has so much force..

    I’ve been playing a lot with Tiger Moths in the past, the friends who owned them decided to install drum brakes and to add tailwheels, so the brake system check was added in the hour inspection list. I remember passing hours laying under the Tiger in order to have all the air out of the plant,with a relevant brake fluid drinking too 😉 but despite our careful checks we had in a couple of occasions a wheel braking more than the other or a ferod sticking to the drum with the understandable consequences.. We have the brake fluid tank inside the cockpit, so it’s not really hard to check, u just open it (carefully, so u can’t eat yr muffin while checking the oil 😉 )Our techie down at the hangar used to tell me that the best ways to spot a braking fluid leak in the walkaround are:
    1) checking the tyre: if it looks “clean” or “semigloss” it might be an oil leakage in the brake area.
    2) following with a finger the tube and checking yr finger: hydraulic fluids tend to follow the tubing lines when the plane is parked.
    3) look for paint chipping around the wheel and wheel bay area: brake fluid is an incredible paint stripper!
    All in all what happened to Janie is an inconvenience that unfortunately is not that rare.. Anybody can have a failure for any reason at any time, this happens even when driving yr car, it’s just a matter of bad luck sometimes. Of course careful and recurrent checks can minimalize the problem, but there are some troubles that can’t be predicted sometimes. A friend of mine, who’s attending the Italian Air Force Flight Academy, was making his first flying hours in the SF.260 and the instructors hammered them with all the emergency procedures. He had a tyre burst on landing and was able to manage it easily, but he said it was mostly due to the fact that there were no aeroplanes parked near to the runway. Accidents can be avoided with a careful airport managing, and above all with a serious attitude of the pilots, who must respects the ground indications, the ground control calls and always look around. This works well with military airports (and nonetheless they have accidents too), but in a civilian airport or airfield it can be difficult to be obtained. The best thing to do is thinking twice, and above all being sure to have enough room around u.

    Cheers

    eheheheheh
    the craziest thing is that the dude there paid for the auction, and according to ebay rules if somebody makes a bid on it and doesnt get the object he might even leave him negative feedback!
    Lonely nights and a lot of beer while in front of yr pc can be really sad sometimes 😉
