I realise they are probably a design concept, whether by Miles I wouldnt like to say, but the combination of such a long nose containing seven people and a short rear fuselage looks like a CofG nightmare.
Miles got the most out of horse power but two Gipsy Majors doesnt seem enough, the Gemini wasnt overpowered carrying four.
Pretty though.

Not to mention the lack of fin area compared to the fuselage area foreward.
