Craft Air - Golden Eagle

Howdy folks...

Been flying gliders since the early 80's. I was blessed to have a father that got his hands on the "best" vintage gliders available at the time. We've built and flown planes like the Aquila, Olympic 99, Super Malibu, Sailaire, and Golden Eagle.

After my brother crashed the first Golden Eagle (silly guy installed an aluminum tube wing rod!), my father bought another one and stored it away. Shortly before he died he started work on it and had a friend assemble the wings. It has been sitting dormant for over 15 years and I've kept it safe in my son's closet...until now.

I'm working on several projects but will update this thread when progress is made. For now, here are a few pics of its current status. Enjoy the show.

Build Notes:

- Thinking of scrapping the spoiler thread pull lines and install dedicated servos in each wing.

If it were me and the spoilers had dedicated servos, I'd scrap them and install pull strings .

Your going to like it. Yes to the servos in the wing. Much easier to fiddle with than string and once you got it setup it is even easier.
Mine is on the repair list. Not enough airspeed on launch and @#&^$*

I built one of these - maybe 25 years ago? I still have it, never flown. I never had access to a field large enough to use a bungee hi-start or knew anyone with a winch.
I was thinking of motorizing mine to get it to altitude. I'd have to clear all the weight out of the nose however. And put in new servos.
For my spoliers, I made up a plug in bar (soldered together brass tubes and square sections) that ran off one servoin the fuse - works OK on the bench, but don't know yet how it would stand up in flight.

worst glider I ever owned

Everytime I slowed it up too much (and there was no way of knowing when that was) it tucked and went straight down. Within 150 feet of the ground it was unrecoverable from this wicked stall. Rebuilt the wings three times. Even added washout. Same problem. Finally threw it away.

And no, it was not building or pilot error. Research at the time revealed that this was a common problem with the glider, you had to keep decent speed on it at all times.

Not surprisingly, this was one of the only designs by Tom Williams that never got popular. The Windrifter, SD100, Viking, and Sailaire had no problems.

Nuff' said.

Had one of these in high school and loved it.

You can make an electric power pod that mounts above the wing - held on by the wing rods.
Replace the nose weight with a lipo to power the motor. Yes, there will thrust issues and you may want to mix in some elevator with the throttle, but this is a way to make it self launching without giving up the option of using it as a pure glider later.

Sorry it has taken me so long to get on this project. Finally went to the LHS to pick up some opaque yellow Ultracote and a box of RIT dye for the canopy. Will try to get the tail surfaces done soon.

Hi
I've got an orphan pair of wings that I think are from a Golden Eagle. Please can I ask if you can measure the chord at the root and the tip, this will help me verify it.
Regards Bill

Bill,

The measurement on my wing is 10 7/8".

Hi Lee
Do you know if the fuselage is identical to the Viking. Please could you measure the length from the nose to the bottom of the back of the rudder so that I can compare to the Viking plans that I have.
Cheers Bill

I seem to remember that the Viking fuse is 1/4" inch longer, an easy mod from the same mold.

Yes, It does look like a Viking fuse. What is the span of the Golden Eagle?
