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.

The flaperon push-pull tube exits the wing skin and is connected to an external drive horn on the flaperon at the trailing edge of the wing. This needs a fairing to reduce its drag. (Beyond the wing's trailing edge is shop clutter and equipment. On the wing is an old pink towel and a pair of left-handed scissors with orange plastic handles.

The aft (smaller) fairing is temporarily held in place with blue tape. This is only half the battle. We also need a fairing on the forward part of this assembly.

Both fairings are now in place. The forward (outer/larger) fairing has been glued to the wing's surface. The flaperon is near the lower limit of its travel.

Both fairings are in place, and the flaperon is near the limit of its upward travel.

Hydraulic jump in the atmosphere over the eastern half of New Mexico.

This animated loop from visible light weather satellite images this morning shows a middle layer of clouds over the eastern half of New Mexico. The location of the cloud is stationary, but the winds are howling up there.

This cloud shows the presence of a hydraulic jump in the atmosphere. The trigger point roughly coincides with the 'central spine' of high terrain in New Mexico that runs north/south.

https://en.wikipedia.org/wiki/Hydraulic_jump

Glider pilots can find lift a short distance upwind of the start of the hydraulic jump cloud. (The challenge is finding other lift to get up there.)

[Edit/add: a cool photo before dawn of part of this cloud formation:

La Marine nationale a reçu cinq nouveaux planeurs sous-marins pour sa Force d’action navale

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.

A yellow tape measure lies along the top of the glider's canopy. The canopy is covered with protective paper and edged with blue tape. The fuselage nose is at the right edge of the frame, which has two folding props covered in bright orange fabric.

The garage floor is gray and behind the fuselage is the clutter of various equipment and sundry items.

Watching Classic Mac Gaming’s video on Glider awakened something in me.

The glider winglets need a protective box during transport to and from the airport.

Now that I know it's big enough to hold them (I'll add foam cushions later), it's time to slap on some leftover red and yellow Rustoleum on the exterior.

#AvGeek #Aviation #ElectricAircraft #Homebuilt #Glider #DIY #EAA

Two white glider winglets sit inside a home made protective wooden box. Each winglet has a short spar, a slivery aluminum tube. One winglet is partly propped up by a piece of light blue expanded polystyrene foam. This view looks down upon a gray shop floor that is cluttered with tools and equipment.

Two cans of leftover Rustoleum. One smaller can, yellow, is in the paint shaker. The larger red can is sitting on the table waiting to be shaken.

After a hasty paint job, the box exterior is now red and the lid, behind the box, is yellow.

The FAA registration number has been applied to both sides of the fuselage tail boom.

Tomorrow I will apply mylar gap seal tape along the junction of the moveable rudder and the vertical fin.

#AvGeek #Aviation #ElectricAircraft #Homebuilt #Glider #DIY #EAA #FAA

The back half of the fuselage tail boom and vertical fin are in a garage shop. The tailwheel is sitting on a box in order to elevate the tail boom to a comfortable working position. The FAA registration number is large black letters on the white fuselage.

Still just blown away that John Calhoun, the guy who made Glider (and several other games in this post on Mac games I'm researching and writing) is still active online with his blog/site https://www.engineersneedart.com and he's put a bunch of the old Soft Dorothy stuff over at GitHub: https://github.com/EngineersNeedArt/SoftDorothy-UnfinishedTales-Vol1.

Also, shout out to @setsideb who wrote about John and his projects a while back here: https://setsideb.com/john-calhouns-lost-mac-games

This video shows the flapperons moving as camber-changing flaps. The two control surfaces move in unison. My flap control system has five settings. The central setting is flaps zero or flaps neutral. Two settings increase the camber more, which is suitable for low speed flight. Two settings decrease camber... this is when the two flapperons move upwards.... and this is suitable for higher speed flight.

Adjusting the flaperons.

This video shows them operating as ailerons. I move the control stick side to side.

Note that at max deflection, the control surface moves above neutral position more than it moves below neutral position. This is the principle of differential ailerons. It helps reduce adverse yaw.

The first comment to this toot will be a video showing the motion of the flaperons as camber changing flaps.

The glider's flight controls need final rigging/adjustments.

First photo shows that the left and right spoilers are extended the same amount, which is the desired condition.

But we need to check and ensure that they also lock (into the over center position) identically.

Second photo shows the view of one of the spoiler drive arms, as seen through an inspection port. I have added black marks to show when the arm is in the over center position.

How do I adjust the action/throw of the spoilers to ensure they are synchronized? By adjusting the length of push-pull tubes, such as the one I'm pointing to in the third photo.

Now that the spoilers are adjusted, I need to do similar checks and adjustments of the flaperons.
