We don't want to make any mistakes in shortening the rods if we're able to, as we are in this case. I like the idea that ~ like choosing snow-skis from the rack ~ we'll be able to select a set of rods to suit the flying machine to our own height.
What I'm doing here is firstly to mark the height of the mannekin on a sample rod that is screwed home fully. We must also allow for the thickness of the rotor-head that the rods will pass through, which is 1" or 25.4mm.
The last time that we flew a drone of this size and shape we did so with motors and flight-controller mounted on the underside. Though we'll be mounting motors on the top-side this time, I'd still like the option to mount the controller in the same place. It is 30mm (1.25") deep and we need to allow for this above the mannekin's head.
I will reduce each rod to allow for all this to 1100mm (43.25"), not including inserts.
