Everyone needs to have that clip on their tablet or smart phone, and show it to any and every kid they meet.

Now if I can just figure out how to use one of those infernal smartie-fones I could practice what I preach.....

"Like!!"

I would have checked my straps too. Very cool. I would like to find the Primary where they launch it down a hill with the bungee.

Looks fun to me! At this point that may be my only option to get in the air for the next 14-15 years.

You had such a glider in your portfolio, a folding one, no?

A rework at the tailsurfaces to more timeles design and strutts instead of cables and voila a glir that could compete with the simplicity of the SG38 butwith a modern design.

Why bothering with designing, when Mike Sandlin already did it and plans are free for use... :grin:

More importantly, several examples built, of several different variations, with a good safety record and demonstrated good flight characteristics.

The only "update" or "upgrade" to the GOAT design would be to reduce parts count and reduce the number of small fittings. This would make it an easier project for schools, or small clubs, EAA chapters, etc. There are already people who have created the files for CNC cutting on the metal parts.

Topaz,
Where can you get good, clear, accurate plans of the SG-38?
How much would it cost to build?
How long would it take?
I've watched the video about 20 times and show it to everyone I can.
Anyone in the DFW, TX area want to build one? I'll be glad to help.
Thanks

I would suggest something crush-able under the seat. Say a 3" block of 2#/ft^3 foam with horizontal holes bored through it. I know of one back injury from a Goat hitting too hard.

Norman,
If I build the SG-38, I'll definitely check with you on specifics for attaching the seat and crush plate/foam.
I read somewhere that some primary glider versions had springs attached to the sleds to help absorb shocks from hard landings. Is that correct?

I just ordered the 1929, 1930, 1931, 1932, & 1933 Flying and Glider Manuals from EAA.org as suggested by Bob Hoover and others. Supposedly, they contain plans and information on several gliders and planes.

I read about the damaged 1930 Waco Glider given to EAA founder, Paul Poberezny, by his high school teacher.
As you know, Paul rebuilt the damaged glider and taught himself to fly.
A Waco Glider replica is hanging in the EAA Museum. I'll have to see it next summer.
Thanks.

Continue along that line of thinking and next thing you know you someone will insist we need helmets!

What good is a helmet if you don't also use a HANS? :gig:

Well falling out or hitting your head on the wing would kind of suck. It's realy no different than riding motorcycles.

Well, if you fall out of your plane, I think hitting your head on the wing on your way out is the least of your worries.

True enough. Just ask Bessie Coleman. Apparently her airplane had been maintained by the fellow in the German Bf 108 aircraft factory.
