A week ago I had my third emergency detached retina surgery. Earlier today the surgeon conducted a one-week post-op exam and said I'm healing fine with everything looking good...so far.
The surgeon deliberately put a gas bubble in my eye, so I can't return to the mountains until that bubble is gone...in 4 to 6 weeks.
Once I get back home, I will do a few minor things to the glider, then assemble it again for a full-power taxi test.
I need to cultivate more patience....

Seeing the news that gas prices has hit yet another all-time high reminds me of my video from December, on the state and future of sustainable aviation
I think it's good, but that opinion is clearly biased.

The glider now has 12 pounds of lead shot and epoxy added to dead space in the very end of the tail boom.
My initial estimate of volume indicated that I could add 8 - 10 pounds this way. I'm pleasantly surprised, and I didn't make a chocolate covered mess of things as I was pouring this goop into the tail.
I need to add a few more pounds to the tail. Phase two of this project will use lead plate, bolted to the vertical fin spar. (I need to unroll the 1/4-inch plate first, then develop a template to cut the lead.)
I could not add the epoxy/lead shot mix all at once because of the exothermic reaction of epoxy. When mixed epoxy is in a thick blob (instead of a thin layer), it generates enough heat to warm itself...which accelerates the chemical reaction...releasing more heat...further accelerating the reaction.... I have seen epoxy smoking hot because of this, so I added a bit, waited a half hour, checked temperature with an IR non-contact thermometer, added a bit more when it was clear that the exotherm was only very mild, etc. That took a while, but turned out well.
I note that Roto Metals has a discount on some 1-inch lead plate. Get your fork lift ready. No free shipping!

The glider's 3rd battery now has a sewn carrying handle that makes it easier and safer to install in the crowded battery box.
Next, I need to devise a retaining system for it and finish the wiring harness that connects it to the rest of the system.
Progress will slow for the next day or two because the things I have ordered (epoxy, lead shot, etc.) will be delayed while we ride out a snowstorm that should end tomorrow.

Where does the 'typical' glider battery go in this electric glider?
In the battery box, next to the high voltage motor batteries.
My final decision on this battery location depended on the weight and balance measurements I made last week. It shows that I need to add weight to the tail...so, the heaviest batteries are full-aft in the battery box, and this 3rd battery goes in front. All of this is aft of the tail in the fuselage/tail boom.
I now need to sew some sort of sack and carrying handle for this battery. It's not a heavy battery, but I want a secure way to handle it as I install/remove it.
Above my hand is a black/gray marbled-pattern object. It's a yoga block. That semi-dense foam will be cut to size to take up any dead space along the sides of the battery box to prevent the batteries from banging side-to-side if the other retaining systems fail.

My glider will use a tow rope that is too strong. That rope, when under maximum pull, may damage the glider.
I need to install a weak link as a mechanical 'safety fuse'.
Here is one weak link system I can use:
https://wingsandwheels.com/tost-weak-link.htmlBut which weak link is appropriate for my glider?
Federal Aviation regulations require a tow rope (or weak link) to have a certain breaking strength with regard to the maximum operating weight of the glider:
"The towline used has breaking strength not less than 80 percent of the maximum certificated operating weight of the glider or unpowered ultralight vehicle and not more than twice this operating weight."
https://www.ecfr.gov/current/title-14/chapter-I/subchapter-F/part-91/subpart-D/section-91.309
To complicate matters, my glider can carry 400 pounds of water ballast. When I'm flying 'dry', I would prefer to have a weak link that is just strong enough for the dry glider, and when flying 'wet' I would prefer a (somewhat stronger) weak link appropriate to the heavier operating weight.
See the second graphic, which shows which Tost weak links I can use in the dry or wet ballast condition.
I will start out getting the weakest weak links allowed (green, yellow, and white) and see if that launches me well without premature weak link breaks.
Pro-tip. Try not to lift the rear end of the ground launch car.

My glider needs the center of gravity shifted aft, so I need to add weight in the tail.
The first photo is looking into the rudder cove (rudder removed). I can bolt some lead plates to the flat face of the vertical fin spar, but I will need even more weight added back here.
Note that the rudder hinge support is glowing green...a flashlight on the other side is illuminating it.
That part is hollow and it's nothing but dead space. I can add lead shot and epoxy in there.
The second photo shows the view of this pale green fiberglass part from the other side. Before I can add lead shot in there, I need to add a dam to retain it while the epoxy cures.
Third photo shows a piece of scrap Plexiglas that fits up against the end of the rudder hinge support.
Final photo shows the Plexiglas dam glued into place with RTV silicone caulk. It has a semicircular cutout that allows a larger diameter piece of tubing to be placed there while I pour lead shot and epoxy into a funnel and fill that empty space.
Half of the caulking work was done blind and by feel. I am accessing this tight space from the inspection port in the side of the vertical fin. There is just enough room for one hand and this part to pass through the port and then get positioned. I practiced before applying the caulk so I knew exactly how to position and twist the part so that I didn't make a mess and most of the caulk ended up in the desired location.

The electric glider's two main batteries each weigh about 16 Kg (36 lbs). I need a positive restraint system that can handle vibration and especially negative G.
Yesterday evening I epoxied in place some retaining blocks for the two battery clamping bars, but the garage gets cold overnight. I placed an incandescent lamp over the top of the battery box and wrapped some towels as a 'tent' to keep the warm air from easily escaping. This allowed the battery box to stay slightly warmer and accelerate the curing of the epoxy.
The second photo shows one end of a battery clamping bar (yellow) that fits under a carbon fiber inverted shelf (black). On each side of the clamping bar there are now two blocks of garolite (pale green) that prevent the battery block from sliding off to the side.
Garolite (G-10) is commonly used as the substrate for printed circuit boards, and you can get it in significant thickness, which is what I need.

For the glider's ground support equipment, there is good news and bad news in the first photo.
The good news is that the eScooter has more than enough pulling power to move the glider about on a smooth, level paved surface.
The bad news is that this version of the red tow bar means that any sideways push against the tail of the glider is transmitted to the eScooter...and makes it extremely difficult to keep the scooter from toppling over.
I had to re-design the tow bar.
The second photo shows what I've come up with. Now the wheel on the yellow tail dolly carries the weight of the glider's tail and reacts to any sideways loads. The eScooter merely needs to provide the pulling force and doesn't have to deal with those sideways forces. That should be much easier and safer for the driver.
The next time I assemble the glider at the airport, I'll give this towbar a final test with the eScooter.

Where is the center of gravity of the empty glider located?
If you measure the location of the main wheel and tail wheel (reference to something such as the glider's nose), and the weight each of them carry...you can do the math to answer that question.
Where is the center of gravity when the pilot is in the glider?
Climb in, and then take the same measurements.
Now I know if I need to add trim weights to the nose or tail, and how much.
Determining center of gravity location is critical for safety of flight and good handling characteristics. I'll do these measurements and math more than once so I can be very confident of the results.

One surface of one glider wing has now been covered with mylar gap seal tape.
Tomorrow I will flip the wing over and apply gap seal tape to the other surface.

Gliders often go to significant lengths to reduce drag.
My flaperons are driven by a push-pull tube that exits the wing skin and pushes against an external drive horn. There are two of these setups on each wing...four external devices that need fairings.
But they and the flaperons move. That complicates things.
First photo shows one push-pull tube and drive horn without fairings.
Second photo shows the inner/smaller fairing that will eventually be glued into place.
Third photo shows both fairings in place and the flaperon near the limit of its down travel.
Fourth photo shows both fairings and the flaperon approaching the limit of its upward travel.
One fairing of the two pairs on one wing are drying overnight. Tomorrow morning, I will make final adjustments to the remaining inner fairings and then glue them in place.
I'm using RTV silicone, which needs humid air to cure well. It's winter in New Mexico and the air is super dry. I have put a very large pot of water on the wood stove to humidify the air overnight.

I need to make a cloth canopy cover for the glider.
Now that I have the canopy installed, I can measure overall length of the planned cover and the width at various points.
I'll lay out a pattern on paper that is 1/4 or 1/3 of the overall width...like gores for a hot air balloon.
I have three different types of stretch fabric from very light to somewhat heavy. We'll see what results I get.
