There are three modules to the 'drone viz. airframe, flight-deck and undercarriage. The reason for this is that like the containerised transport system, the design features a four-cornered means of connection forming the basis of a modular system that offers (a) choice of undercarriage whether skids, floats or castors (b) choice of payload whether seat, stretcher or cargo-box and (c) choice of four or eight propellers.
Altogether, you're spoilt for choice. We'll first build the frame to which flight-deck and skids will be attached, the recipe for which module includes the following:
(a) 4 off 58" and 4 off 38.125" by 1/16th aluminium square tubing, cost £36.47
(b) 2 off 19" square 1.20mm plain aluminium sheet, cost £32.40
(c) 4 off 25mm four-way steel-reinforced tube connectors, cost £44.19
(d) 8 off 25mm square 6M threaded inserts, cost £5.87
(e) 8 off 6 x 40mm hexagonal bolts at £0.40
(f) Total metal/plastic parts airframe, £119.33
That's just half the cost of lunch at a Michelin-starred restaurant, and you can't share that. Leave those ingredients indoors overnight, as warm alloy is more workable.
