Hmm, I skipped a step taking my own measurements yesterday for my sewing exercise. 🤔

Ergonomics, note the height of the table this tailor uses. The height of the dining table I am using is way too low... having to hunch over kills your back. This table is at workbench height, the same relative height I have my standing desk set at probably... 42 inches, so you don't have to stoop to type on the keyboard. Dining table is 42 inches. Probably could replicate this by obtaining one of the (plentiful) standing desks and putting it on a pivoting hinge, if so desired. (I don't do this often, but if I did). #tailoring #ergonomics

@ai6yr@m.ai6yr.org After crawling around on the floor for a lot of years, I just just gifted myself with a Rodulf table from Ikea. My back is very happy. I can cut standing up straight with my elbow bent at a comfortable angle.

I made the wing support sawhorses so that the top of the wing was at about 42 inches.

@KrajciTom@universeodon.com Oh, brilliant... that really helps with the back comfort, IMHO.
Wing-as-desk is unique!

Wing-as-desk. Good for all that building and tweaking.
In a couple months I hope it becomes wing-as-wing.

@KrajciTom@universeodon.com Good luck! After you finish building it, I assume there's some kind of certification/check before it gets to fly?

Now that everything is painted, I will assemble the entire glider and do a weight and balance evaluation. Then, I will sit in the cockpit and do another weight and balance evaluation. Then, I will quadruple check all of those measurements and math.
If I need to make a big adjustment to the center of gravity, I could install a heavy lead acid battery far from the center of gravity.
In order for the FAA to issue the airworthiness certificate, this plane must undergo a condition inspection. That opens the door to a flight test protocol where I gradually evaluate and demonstrate that the glider flies acceptably well.
My first efforts in flight testing will be taxi tests where I never even get fast enough to become airborne. Gradually, I will expand the envelope to higher speeds, higher G loading, a wider range of angle of attack, and evaluation of flying characteristics with the center of gravity at the forward maximum position and the aft maximum position.

"On 22 July 1966, Walter "Taffy" Holden, a 39-year-old engineer in command of No. 33 Maintenance Unit RAF with limited experience flying small single-engine trainer aircraft, inadvertently engaged the afterburner of a Mach 2.0–capable English Electric Lightning during ground testing at RAF Lyneham. Unable to disengage the afterburner, Holden ran down the runway, narrowly missing a crossing fuel bowser and a de Havilland Comet taking off, before taking off himself."

@KrajciTom@universeodon.com @ai6yr@m.ai6yr.org Yes that's the story. However as you don't have an afterburner you should be quite alright.

The electric motor system has a canopy switch. If the canopy is open, the motor control unit throws an error and displays a "Canopy" error message.
If you override it three times, the motor can run with the canopy open.
Up to now, this is how I tested the electric motor...with canopy open and me standing next to the cockpit.
