Restoring the classics, free-flying gliders

Restoring the classic free-flying glider I had to be present at the sad event. I saw with my own eyes how the aircraft modeling circle was killed. Which was led by the Master of Sports. I called and offered to pick up a couple of portable safes with models, it was a pity to throw them away.
The funding was cut off, not the Olympic “direction.” Karate players, boxers or maybe, God forbid, football players?
Okay, distracted. What I see.
A couple of solid plywood boxes for transporting models. They contain a bunch of gliders almost intact.

Nostalgia ..
They don't build so well now from wood.
Restoring the classics, free-flying glider With words of gratitude, dragged to car.
After that there was a strong desire to restore the glider class F1A.
I chose a couple of the most survived.
So what is there.
A real timer wick.
Restoring the classics, free-flying glider Fuselages.
One with a wooden tail boom, the other with fiberglass.
Restoring the classics, free-flying glider Rudders are made of balsa, almost intact .
Adjustment elements too.
I explain – at the start, the halyard pulls the starting hook and the control line sets the rudder in a straight line.

After two minutes of flight, the wick burns through the thread and the elevator rises vertically at an angle of 45 degrees and the glider falls into parachuting.

There is a crack on the wooden fuselage, already repaired.
I spread epoxy, glue the crack , then wrap the damaged area with thin fiberglass. On top of the film and fix everything with masking tape.

The second fuselage made of a thin fiberglass tube is completely out of order. Unfortunately, I do not have such a mandrel to make a beam. I dug in the bins, found a suitable carbon tube.
With the remaining epoxy I glued a new beam into the fuselage and installed all the elements on the tail.

They fall apart in the hands.
The weight of the structure is about 9 g. I need to make it much easier, because I decided to cover the models with film. It is heavier than mica paper with enamel.
I am making a copy from the elevator ribs. Small, thin. I have never made such an elegant design.
Made a template from thin aluminum. I fasten it on the balsa plate with needles and a scalpel, carefully, cutting out the ribs one by one.

I did not succeed in soaking the mica paper with acetone. Therefore, I cut everything out with a scalpel. To remove the glue from the ribs, I made several irons with soft plastic sandpaper. I glued everything together with cyacrine. He fixed the skin with carnations.

Everything is ready for flights.
It's windy and cold on the field. But tests need to be carried out, to find out how everything is set up.

Restoring the classic free-flying glider During the next training trip, we held test starts. Children, too, threw away from their hands.
Adult guys started to run. We are not specialists, it turned out crooked.
But the glider flew!
I was a “horse”. Perfectly felt the plane on the handle! Inexpressible sensations!
Launched from the hand.
flew, waiting for summer to fly in thermals.
