    CD, a rather simplistic view, as often happens when the Snatcher is discussed. Did you forget Germany?

    Contra props had been used on the Koolhoven FK 55 fighter c.1935 and on one of the Macchi Castoldi MC72 Schnieder racers in the 30’s. It’s interesting that the Contra Spitfires needed a bigger rudder.

    The MC72 did not have a contra prop in the same sense as the ones discussed previously, as each airscrew was driven by a seperate crankshaft within a combined powerplant. They were independent and so could rotate at different relative speeds. The rear airscrew was more efficient and was driven by the front v12, the front airscrew was driven by the rear v12 which drove the supercharger that served both parts of the engine. No means of synchronising the airscrews existed other than adjusting the pitch on the ground. The two v12s were design to run at the same time.

    A similar arrangement was used on the Fairey P24 Monarch, except each half of the combined engine could be run independently as they had individual ignition and fuel systems and had VP airscrews.

    It would infringe:
    A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
    .

    So, all these people bearing arms, including the ones killing people in schools and colleges, are a “Well regulated militia”?!? What regulation allows for such atrocities?

    I can see no evidence of this organised militia from here

    What is the current need and purpose of a militia in the USA at the moment?

    P.s. When demanding personal details from others, it is polite to say “please”

    Thank you, TwinOtter23. I’ll certainly pursue that lead. But I have to say that I’m a little surprised that no SVAS members have offered help. But maybe they are not permitted to do so?

    It may be that SVAS members such as myself don’t have an encyclopaedic knowledge of their engine collection and live 130 miles away and won’t be returning to OW till around Christmas time. If you can wait that long………

    If you have a large number to scan, a dedicated film/slide scanner makes the job easier. Something like the Nikon Coolscan IV or V. But even second hand they’re nearly twice your budget. The reviews of the V600 look very positive for the price point.
    As you appear to be suggesting, use a viewer or projector to sort them into possibles first-just scanning everything is a ……waste of time
    Be prepared to spend a lot of time doing this even after sifting. Much, much longer than you would expect. It can get very boring. I speak from personal experience!

    From post #388

    not with other people’s money

    Here we go again. I almost resisted, but then thought s*d it

    Sorry to be boring, but…… It is not other people’s money, it is their money. Other people may have given it to them but on the basis they would use it to keep the thing flying,which is what they are doing.

    If you had won money on the lottery, would you be happy for anyone who had ever bought a ticket to tell you what to spend it on? Or would you be happy for your boss to tell you how to spend the money they pay you each month?

    I don’t know of anyone else who holds your position on this specific issue. I am sure you are not alone,but certainly not in a majority as far I am aware

    I am sure I read somewhere that contrarotating airscrews are actually more efficient aerodyanamically than a single airscrew with equivalent blade area as the rear airscrew is working in the tangential airflow from the front which makes it more efficient. The figure quoted was about 10% I think. I’ll have to look it up. However,the mechanical losses can counteract this gain, leaving the main advantage in reduction of torque reaction.

    In marine applications, contraprops have shown fuel consumption reduction in the order of 12% at partial load

    I read the title of the thread and assumed you had found an article in The Mail that was accurate.

    Moggy

    Was it 1967 or 1968 that this occurred? Can’t remember.

    No I tell a lie it was 14th February 1997.

    In the mind of most who have the luxury of living in a gun-free environment.

    Moggy

    Absolutely agree.

    Maybe not, but I would guess that the vast majority of people on this forum would be there given the chance (

    You are probably correct, but I am not one of them. I really do hope all goes well, but will be relieved when it is all over.

    I can not understand the fascination with seeing it take off or land at Doncaster.

    Ditto
