FYI (and any other who may be interested) the Mark Lubbock Midge was published as a two part article in the UK modelling magazine 'Aviation Modeller International' some years back-in the mid to late 90's IIRC (somewhere ca 1997 or '98) I think it spread over two issues that were not quite consecutive-March and May or April and June from memory but I'm not 100% on that. I think I've got them here -but they'll take a bit of digging out! I have got a rather poor photocopy of both articles which I can copy and snail mail if needs be, if you get no luck elsewhere.
NZ's John Malkin, one of the grand old identities of NZ aeromodelling has built one, and I've not only seen it running but seen it flying a sport model at our Nationals a fews years back. I think he 'imperialised' his one, as the AMI article was in metric dimensions.
