Important at every stage to keep visualising the eventual outline, something that auto-makers have always done, once in timber and clay but increasingly using 3-D models in both hardware and software.
These here are the 18-inch struts, tho' when I look at them (and my original sketch) they look too tall... auto-makers at this stage look for qualities like 'stance' and the extent to which the vehicle pleases the eye.
I'm not best pleased with this, and shall remove the 18-inch jacks and take an inch off either end. If you do this yourselves ~ though you may prefer to sit back as ever and watch me screw things up ~ I recommend you mark which timbers go where in order that the screw-holes line up afterward.
I've also had messages on the forum asking if it matters what tins of tuna are best suited for this exercise, and whilst mine are in brine those in sunflower oil should do equally well.
Smaller struts will also lower efflux from the propellers further into ground-effect, a measure that improves its chances ~ literally ~ of getting off the ground.
