This is how the airframe looks in one-inch alloy instead of 20mm square. For those who want to join in, when drafted in Word or Pages 6 and 7 point relate to 20mm and 25.4mm at tenth-scale on A4. Framed they make the perfect Christmas gift... and yes, I have been known to.
When it comes to prototyping perfect is ever the enemy of the good, and whilst it may add slightly to weight in other respects ~ specially as regards unwanted harmonics ~ it improves matters.
Principally though the reason for it is that I can source materials more locally and less expensively at one-inch than at 20mm, though nice to know it's there. That includes the foam insulation used to pack the centre-section, as well as the unplaned wood used to reinforce its corners.
Don't knock wood in aerospace... it served even in fighter jet parts until late in the day.
