Not an old flame of mine but the technical term for the colour, as defined by the military in the UK at least. I shall revert to pillar-box red for display purposes, but this will suit for the flight-testing. Also the airframe I shall donate to some or other museum thereafter, and it won't look out of place at Middle Wallop for instance... the spiritual home of the Army Air Corp in this country (recalling too that the Royal Air Force began life as such, and that the British army reputedly have more airframes then do they).
Also pundits have let slip the feeling that flying phone-boxes are a little too fanciful, quoting the brothers in Germany who recently flew a bath-tub by similar means. What most of us do not realise however is that they likely chose a bath-tub as a ready-made alternative to building something altogether similar but at great cost in terms of both time and money. When I taught in flight simulators or "synthetic devices" the manufacturers of such were rapidly subbing COTS or Commercial Off-The-Shelf components for what were previously bespoke... so don't knock it.
My preference has always been for motors mounted upright, too, but whilst this is an option for larger accommodation boxes supporting enclosed operators whether standing or seated, it was clearly not an option here for safety reasons. But why this version anyway? Well, to reiterate ~ anything larger falls foul of the (restrictive) dimensions allowed by the ongoing GoFly challenge.
