I bet that'll be fun to fly! Reminds me of the 1938 Short S31, a half-scale model of the projected Short Stirling bomber: it had four Pobjoy Niagara radials, spanned about fifty feet and was, as far as I can tell, a single-seater. By all accounts it flew beautifully but had too long a take-off run, which is why the Stirling ended up with such a weird, ungainly undercarriage - the only way they could think of to increase the angle of attack when it was on the ground.
