I have this 6 channel sailplane, with a wingspan of approximately 3 meters (see pics). During a recent move across the country, the wing rods got lost for the wings and vertical stabilizer. How exactly do I get a new set of rods? Any suggestions?

I have no clue what type of sailplane this is. Got it a few years ago from an old club member who no longer flies, he doesn't remember what it is either. Apparently it's an older model. I'm thinking if i knew the make of the sailplane, it would facilitate finding replacement parts?

Dixiepins. Hardened mold ejector pins, in inch or metric.

Lincoln Is the man to ask about this one,He will probably know what it is .
As far as the wing rods go there are a number of sources for the rods, are they carbon fiber or aluminum?

Looks like a Pulsar from Bob Sealy. I could be wrong but that is what it looks like to me. He sold 2 or 3 versions of that sailplane.

Looks like a pretty Falcon 880 to me!

Determine the length required by measuring the depths of the tubes in the wings and stabs, and the length needed to reach through the fuse. Use drill bits to accurately guage the rod diameters. Most planes from that era used music wire rods. Ejector pins are better.

It's a Pulsar fuse, with a different wing on it, maybe. The Pulsar had a 100 inch wing if I remember right. Maybe there was an Pulsar XL at one time....

Send diameter and length. Steel, Stainless, Aluminum, ejector pins, etc.

Thanks guys. This aircraft originally had stainless wing rods. What is the advantage of the ejector pins vs stainless?

vintagesailplnr · Sep 16, 2011, 07:18 PM

SS will not rust!
Ejector may tarnish in time - but rubbing with 400# steelwool will solve the tarnish problem.
Thanks

Moi? I want to say Dodgson Saber, but I don't think the area of the fuse near the wing is right. Otherwise, it seems similar. But I'm not sure what makes me an expert!

Don't think it is a Dodgson Design...

Believe that the planform on the Saber was like the Windsong/Lovesong/Anthem, single taper from root to tip.

Vertical stab/rudder looks awfully low-profile as well (though it could be 'compression' from the camera angle).

I distinctly remember that the Saber was NOT a single taper. It also had a shorter span and lower aspect ratio than those others.

You can use Carbon fiber rods for the tail feathers; take your stabs to a local hobby shop and fit them. You'll have to buy a 36 in piece of two sizes, but they're cheap. Your could also measure the size and order from:

http://www.acp-composites.com/home.php?cat=4662

I would use Al for the main wingrods because of weight. An 18 in 7076 rod, 1/2 in dia, weighs around 5 oz whereas a similar size steel rod weighs 16 oz. Of course, in windy situations you may want the steel.

Bulk 7076 Al rod cut to length can be obtained from:

http://www.speedymetals.com/c-8369-7075.aspx

You will then need to 'BEND' the Al rod to approx 5 - 6 degrees creating a little dihedral when installed in your plane.

Note - you need the stronger 7076 rod!

I just went thru this process...I bent the 7076 using two pieces of regular pipe. I practiced on the less strong 6061 rod that I obtained from a local bulk metals shop. I paid $12 for three pieces of 6061, cut plus the two pieces of pipe... IMO, Your not going to be able to bend the steel rod with this process!!! This shop did NOT carry the stronger 7076 Aluminum rod, although he could order it.

If you determine you really want the 6061 rod, I will give you my bent practice piece; you pay for the shipping. I'm sure it would work, but it won't hold up to a full winch launch so that is why I'm not going to use it. 6061 is only what is available today pre-cut/bent from stores on the net, if you can find it, which is why I went my own route. It was a fun project to go thru.

My plane flys beautifully.
