Oldies Glider plans

[the mole]

Here's some old glider plans I found. They date back to 1991. I believe there was some instruction for the build, but I don't have them.

The basices of the glider system is you measure out the weight, install it in the glider.
The ejection charge pushes out the weight at the end of the flight, to turn the rocket into
a glider.
Maybe someone here might have the instruction. Just thought you might like see these plans.

Nice plans. Can you get a clean scan to post?

[the mole]

I'm sorry but this was the best I could do.

What substance was used for the electable measured weight? Was it encased in an empty engine block? . Can you provide a tiny bit more detail please. The models are beautiful looking birds.

I'm sorry but I am out of town right now. Whin I get home I will look in some places,and try to find the instructions.

Any word on the Instructions yet ?

[the mole]

I'm sorry, :( but I have looked high and low for the instruction and had no luck. It's hard to believe I am the only one who ordered these plans back in 1991. I thought by now, someone would have seen them and had a copy of the instruction. I have tryed to find something on the net by searching for the company that made the plans. Maybe someone else might have better luck. The company was SPEED DESIGNS 28 W. GOVERNOR DR. NEWPORT NEWS, VA
I ordered them out of a Popular Mechanics mag.

That address comes back as a house . . . Not really a surprise, though.

Thank to the mole you for looking.
Does anyone have any idea what the electable material was?

I believe that THIS may "shed some light" on the Ballast System . . .

Great find. I'm sure the instructions weren't that long, but I believe one might be able to build them useing whats there. I think the ballast materal in the instruction was eather suger or sand.

When I have some time tomorrow, I'm going to read these pages over good.

Once again great find. Are you going to try to build any of them?
I would like to see one of them built.

Yes, I want to build them. The first thing I want to do is get them printed out full-size, so that the ruler on the pages is 1:1 scale. Then, I'll try to put the dimensions in place on the plans.

Once I get that done, I'll re-post them here !

Perhaps I should read the patent before speaking but I am wary about using sand or sugar as the ballast material. Sugar is sometimes used as a fuel element in some types of solid fuel engines. And as for sand, somehow it just does not give me a warm and fuzzy feeling mo matter how miniscule the sandstorm created. I am inclined to suggest a material such as baking soda because it is a fire retardant. To quote from the following website:

http://humantouchofchemistry.com/why-does-baking-soda-extinguish-fires.htm

Baking soda is chemically known as sodium bicarbonate. When heated to a high temperature, the chemical properties of this salt make it produce lots of carbon dioxide and remove oxygen. This then totally reduces the amount of oxygen in the surrounding atmosphere and puts the fire out. This reaction also produces a small quantity of water and sodium carbonate as by-products.

My thank you's to the Mole for the plans and continued support and to Ez2cDave for the continued research and patent info. I am intrigued by the possibility of reawakening one of these beasts

Just for fun here is the canard trainer with a 1x1 grid superimposed on it. Since in the original image the camera was not exactly perpendicular to drawing there are minor errors.

Keep watching . . .

Great things are going to happen, as soon as I can get a little free time to get this project started.

The "Mole" already knows what's "in the works" . . . MUWAHAHAHA ! ! !
