    Yes, or perhaps the Hasegawa examples, but I was trying to limit the size of the post. At the same time Fujimi, Nitto, Midori, Edai and Matchbox were producing in 1/76: Hasegawa never had a large range and ESCI went out of business, so I think it is justified to argue that 1/72 only really took over after the fall of the Iron Curtain. The only other survivor in mainstream kits is Fujimi, and they’ve just started releasing in 1/72. As indeed have Airfix, at least with their Airfield sets.

    1/72 scale ( 1 inch to six feet ) was introduced in the 1930’s by FROG so I believe and was adopted during WW2 as the scale for aircraft identification models. It pretty much became an industry standard until the 1970’s I think.

    This could be Hurricane mk1 P2921 painted as 32 Sqn GL-Z, flown by Peter Brothers.

    Don’t know who owns it though.

    I would have thought the dog would simply be called “Dogs Body” ? And I bet they still show him colliding with an Me109 !

    As an observation, none of them appear to have any rank badges or aircrew brevets. Could they be in training as mechanics and the old Wimpy have been retired as a training airframe ?

    What do you want them plated with? Are they for show or are they for ‘in service’ use? Hydrogen embrittlement can be a problem if the latter is the case.

    There are numerous plating services on offer for vehicle restoration, not always cheap as a lot of work goes into the preparation ( cleaning & polishing ) before plating. Items can be plated with zinc, copper, chrome, nickel and even gold and silver but I don’t think cadmium is available anymore. For zinc plating there are DIY kits available which can work out much cheaper in the long run. try googling something like “zinc plating services”. I have restored a number of motorcycles and found that you get what you pay for, I’ve used the cheaper places with poor results!

    I have seen shiny red/white Gazelle helicopters temporarily camouflaged using a matt water based emulsion paint back in the 1980’s. the paint lasted a few weeks but was eventually washed off using Teepol and scrubbing brushes.

    When an aircraft with a rotating prop strikes the ground at a shallow angle the blade tips have a tendency to curl around backwards. If the props were unfeathered there is a good chance they were windmilling. The lack of tip curl and the apparent lack of damage to leading edges suggests they were feathered at the time of impact and not rotating. Was this a crash or a forced landing ?

    There was thread here on this subject a while ago discussing in depth.

    How does this then in your opinion add up with most single engine propeller aircraft touching down with the throttle at idle, including many WW2 fighter aircraft?

    Hi Kenneth,

    Even at idle there is still airflow from the prop, eg, when doing stall turns I would throttle back to idle and kick the rudder when forward motion ceased, there was enough waft from the prop to turn the aircraft. I would also suggest that the approach would be made with some power applied to control altitude and chopping the throttle before flaring. May I ask your opinion re the meaning of “dead stick” ? Do you think the loss of gyroscopic effect would have any effect on control ?

    So are you trying to say that you need airflow from the propeller over the rudder and elevator in order to be able to land an aircraft without problems?

    Within the context of this thread it would certainly reduce the control response wrt rudder & elevator. Obviously gliders & jets are designed taking the lack of propeller into account.

    IIRC the term was originally coined circa WW1 when props were made of wood – ie a stopped prop was just a “dead stick” but the meaning changed over the years partly for the reasons I have given and now even a jet making an engine off landing would still be referred to as a “dead stick landing”.

    The title and early posts refer to a ‘dead stick landing’, a phrase I have heard elsewhere. Why ‘dead stick’ when it’s the motor that has died?

    Because there is no airflow over the rudder / elevator from the propeller when the engine is stopped thus reducing the control authority and making the stick feel “dead”. Not a problem if you have enough airspeed but when you slow down to land…..

    Avpin is Isopropyl Nitrate ( 3 Oxygen atoms ) and not Isopropyl Nitrite ( 2 Oxygen atoms ).

    Quite different properties and uses.
