    Can’t argue with that, give me a Cat any day over a Spitfire

    Catalina – an American Beauty!

    Think of it in terms of moments – the length of the arm from the centre line of the aeroplane to the undercarriage leg.

    the arm is much shorter in the case of a Spitfire than a Mustang. There is increased kenetic energy as you said and that equates to a force applied to the end of the ram. The turning moment will be greater in the case of the mustang than the Spitfire and the aeroplane will start to turn. This turning force can be offset by a force from the rudder to some degree.

    The end result was a Spitfire could land with a flat tire, a Mustang cannot, it cartwheels.

    Used C172 as an example because it is well known, so substitute C170 in there so that is a taildragger. Remember these pilots more than likely trained on Tiger Moths so taildraggers were familar. Mustang a taildragger as well.

    however you are correct in the with your C of G comments, however I threw in the flat tyre to alter the normal situation.

    Weight of an empty Cessna 172 – 1,691 lb.
    Weight of a dry RR Merlin engine – 1,640 lb.

    Interesting points JDK But how relevant when the question was comparing the u/c track widths and the perception that a Spitfire has a narrow u/c.
    Give me the wing span of a C172 and that of a Spitfire

    For those with an engineering bent, think turning moment and arms and forces, the question was of analysed and discussed during WW2 according to Alex Henshaw (second hard account told to me by Mike O’Sullivan of Supermarine Aircraft – designer/builder of the Spitfire replicas).

    The answer is that the Spitfire had a much better survival rate with the narrow track. We often hear that the narrow track caused a lot of landing incidents, but the track is similar to a C172/182/210 and noone ever says they have a narrow track.

    The Mustang tended to cartwheel because of the wider track. I guess that landing on a hard surface like we tend to do these days the effect mightn’t be so pronounced but with soft landing surfaces it was of significience and the Mustang killed a lot of people because of it.

    Thought it would make a good discussion topic

    AJ March excluded because he knows the answer, why is the Spitfire better, explain in technical terms and just to add complexity, which has a wider undercarriage track a Cessna C172 or a Spitfire?

    Those ones aren’t dropping bombs on kids or launching missiles at them….The actual number of operational drones dropping bombs or launching missiles is in the dozens.. NOT 40,000..

    As I understand it, the shift is on, more fighting is being done by drones than manned aeroplanes.

    A rethorical question, “In general terms,how long can a drone stay aloft compared to a manned aeroplane?”

    Another rethorical question “Which is the most cost effective?”

    They are the typical drivers that are powering the shift and that puts the focus back to my original point, the people at home are directly involved in the killings and that drives yet another set of ponderables.

    For my displays , im at least in my prime – 30s or just past it :).

    Im a tall fella for me im a 6’3 225lb bloke.

    10years ago i weighed 180lbs tho… so lifestyle and working does catch up with people…

    I did find climbing into the Sabre jet with parachute on tad hard few years ago… 🙂 needed to do more stretches…

    Doing a P-40 display last year was interesting – the P-40 is so roomy cockpit…

    I do agree with some people that an age or physical constraint is maybe suitable for some renactments.

    More important the stuff is preserved for future generations i feel.

    I met the family of a very famous RAAF pilot at the HARS airshow this year while i was dressed in my 1960s RAAF Sabre gear. I was actually quite a popular item to photograph as most of the public had never seen the flightgear before on display and asked questions.

    The family thought someone honouring their father’s role was most humbling and appreciated. Their dad’s name was on Sabre jet for display.

    I commend you, looking at old aeroplanes is interesting but I think I have one fly-in/airshow too many with the current format in Australia, we need more re-enactment – flying gear displays to revive my interest. Ex-military vehicles are always a great interest and add a lot of value.

    Of particular importance is the value they add in allowing photograhers to get a complete picture the vehicle, plane and the crew back in period attire.

    I have enclosed an image from 5 SQN RAAF Operations Log showing the typical vehicles thatthe squadron had at the time they were at Toogoolawah in 1942/3 (now Watts Bridge). Wouldn’t it be great to see some of those vehicle types given pride of place along with the aeroplanes.

    Well the biggest aviation event in my neck of the Woods is the QVAG Festival Of Flight at Watts Bridge and I don’t recall seeing a lot of them there – maybe the odd one or two, certainly a lot of very interesting ex-military vehicles.

    Would love to see it in an organised way.

    Didn’t reasile that original ww2 webbing is valuable, wonder what one of those strap on HF field radios is worth in its original box complete and working. I was thinking of tossing it but couldn’t bring myself to do so. Got a lot of Marconi radio units out of a Canberra as well HF units from the equipment bay.

    ummmm – what Proctor/Auster/Tiger bits can I swap them for! Remember aircraft restorer rule number 1 – never give anything away swap for something you need or can swap on. Gets around the awkard question of money.

    Daniel, what shows have you done around Brisbane, Australia

    This thread has become more interesting than I thought it would even though someone edited out a traditional Australian word from my post, I think it was ******. We Australians have it portrayed to us that we are disrespectful of authority figures.

    However our Kiwi cousins (to whom we are very disrespectful and keep asking them about sheep) seem to get right off on this dressing up. I am thinking of “Wings over Wanikia”. Not only do they have people dressed up, but they recreate many bits of military machinery and wage mock battles. Very good theater and attracts a lot of Australians over there to see it.

    We get the convict bit bought up but they were all English, Irish and Scots anyhow, so I don’t think that’s it.

    In the WW2 battles Australia were the first to really beat the Japanese, that is true and its only in recent years that has received any publicity. I wonder if it could be because we are a relatively young country (that is if we ignore the Australian Aborigines who have been here continuously for about 60,000 years which makes our culture one of the oldest in the world.

    There is a term often used in Australia called “******” and I can tell you that if I dressed up then I would feel like a ******.

    Having said that, I would love to see the custom of dressing up to come into fashion in Australian.

    Maybe your reverse logic question is the right one to ask.

    We do have medival re-enactment groups and they get right into in, but it hasn’t caught on with the ex-military groups in any big way.

    With a name like that guy that signed that document, you would have to say “Sir, YES SIR!” What a great name.

    The actual document as you say makes interesting reading. thanks for the link.

    I never think about non-flyers, not interested in them. However saying that, non-flyers I imagine should be as close to the original spec as possible, no good reason to do anything else.

    Interested in the comment “it seems that in the UK, Ceconite is legally no longer an option for flying aircraft where natural fibres were originally used.”

    In general terms, could someone elaborate further (appart from the comments that have already been made).

    I would have thought that an engineering order could be obtained if necessary to use another fabric.

    cheers
