    Would anyone happen to know the whereabouts of a crank or complete
    engine for a 1940's Flying Flea?
    Mine is knackered following the working loose of the flywheel,

  2. that's something of an unlikely one. Was it the same as the engine for
    anything else?

    There's a more-or-less compelte Flying Flea up in that aero museum in North
    Wales. Amazing. Does yours actually fly (given a working engine?)

  3. There is also a flying flea that hangs from the hanger ceiling in the
    museum at Old Warden near Biggleswade, Bedfordshire.

    Go to

    to hear Mr Chumleigh Warner telling you all about Mr Appleby and his
    home built Flying Flea with bw film of take off, flight and crash into
    ploughed field!

    This looks like a modern reincarnation though. The link to his web site
    didn't work for me sadly.

    Then there's this one:


    To my untrained eye it looks like a beetle engine, which is almost a
    bike engine, so ought to qualify as a sort of honorary SOB really.
    Certainly in the spirit of UK.R.M.C. anyway.

    Umm, I wondered about this a few days ago - thinking "Bet the little
    flying flea plane would have used an engine out of something else". Then,
    a moment later, I thought "Hold on, wasn't it French?"

    <quick google>
    Yup, it was.

    So "ENFIELD"...?

    <quick google>
    Umm, an _Enfield_ Flying Flea is a motorbike. Not a plane.

    WW2 air-droppable 125.

    Especially the part where "...the tiny machine plunges headlong into a
    ploughed field..."

    We knew that!

    I especially like the idea that it needs a drip tray, and appears to
    have no front brake (or is that a small drum, RHS?). It does have a horn
    and a speedo though :).

    I'm not sure I understand that cylinder head though: spark plug is RHS,
    but what's the thing on the LHS? Surely it's a simple stroker?

    Presumably in this case for stopping the engine as a 75cc wouldn't need one
    for starting purposes. However, if the engine self-generates the spark then
    decompression would be simple way of stopping it.

    Thus spake Dudley Simons () unto the assembled multitudes:
    There were also a number of flying fleas in a certain Brighton cinema some years ago, as I recall.
    It wasn't nicknamed The Flea Pit for nothing.

    True for the early version, though later versions had a linkage to the
    rear wing as well, which solved the slot effect problem.
    Unfortunately, this rather compromised Mignet's original philosophy of
    utter simplicity.

    It has to be said that part of the problem was that many
    constructor/pilots had more enthusiasm than skill in both building and
    flying the aircraft, which accounted for at least some of the

    Tiz a bit weird.

    Even at 125 (or 175), it's still not really necessary for starting, and
    a single switch on the LT side would be loads cheaper than the necessary
    machining for a decompressor.

    Still, thanks for the explanation LW et al.
