It's what they say in the airline industry when the design has been put to bed and the machining starts. Except in my case they did the cutting for me, and thanks to Simmal for bespoke lengths of inch-square tubing at sixteenth gauge.
Unlike the 'dog-bone' design some posts ago in support of eight motors, the airframe for the quad extends its outline four-square and thus uses a little over stock five-metre lengths of tubing.
What I've done here then is to divide the three components between the two lengths so as to be left with identical two-metre-plus offcuts:
Four off, airframe sides at 34" apiece.
Four off, cantilevers at 550mm apiece.
Four off, platform sides at 10" apiece.
(a) Note that the airframe sides are 34" because they are joined by right-angle connectors which each occupy an inch.
(b) Note that the cantilevers demarcating the centre-section are at 550mm because the overall length of 22" has to be foreshortened to allow for threaded inserts.
(c) Note that the passenger platform will match the centre-section at 12" square, from which 2" has been subtracted again to accommodate right-angle tube connectors.
A benefit of half-scale is that it fits the car, which means motors and electricals will not need weatherproofing for transport... as I've paid heavily for in the past.
I've suffered for my art, and now it's your turn.
