A very geeky post this evening...
Last significant design decisions were sorted today. I wanted to do a removable wing - I've done one on my MS P47 that straps in with Velcro, but after seeing a really slick system on a Corsair on YT wanted something a bit better.
So - the battery box is extended rearwards so the wing can hook in directly, and all the flight loads from motor, wing and battery mass all go directly through the battery box.
The front of the wing has a section of the upperb surface removed up to the spar, which has a wooden strengthening brace with two location pins inserted (tongue depressor stick and bbq skewers respectively). The wing slides forward onto the pins, locating the leading edge.
At the rear, a box structure added below the battery box carries another locating pin (to locate the rear of the wing laterally) and a magnet off a conference delegate badge (which had been in my useful junk box for several years) to hold the wing in place.
Fitting is very quick - slide the front onto the pins, then drop the rear with a very satisfying "clunk" sound onto the rear pin and magnet. It works!
Here are the dull pictures.
