Complete a project in 2014: Baghdad Birdie

A millennium ago, when the Middle East was an exotic fantasy land to the West,
a legend originated about a famous sailor, Sinbad, who hailed from Baghdad, who managed to wreck every ship he ever got hold of, but always managed to get back home. Given Sinbad's abysmal record, it seems curious that designer Henry Struck decided on that name for his series of three towline gliders. Since Berkeley Models produced Sinbad the Sailor, Sinbad Jr, and Super Sinbad kits by the thousands, the name must have had some magical, mystical quality despite its association with wrecked ships!

I've elected to build a 150% version of Sinbad Jr from a plan I obtained a few years ago. But, not being smart enough to leave well enough alone and just build per plan, I'll modify some stuff to suit my own preferences.

To see one built the proper way, see Owlsabie's Sinbad Jr. thread. http://www.rcgroups.com/forums/showthread.php?t=1300142

Thanks for the Super Sinbad link, Sundancer! I see he used traditional Ambroid cement! Most of my building is also done with Ambroid, although so far I've used Titebond on this one because it's cold here, so the windows are closed.

No new photos - just preparing a fixture to make laminated rudder/fin outlines.
BTW, would you people suggest rudder only, or rudder and elevator?

Geoff - I'm not a purist, and certainly don't build as accurately as you, but even if only because of the need to survive a maiden I would have both an elevator and a rudder. Mine actually flew and glided fairly quickly, and a bit of up elevator slowed her down nicely. Of course, once properly trimmed you don't really need the elevator, but I still think it helps a bit with smoothing out landing, and with those long floaty gentle glides into the breeze while you look for thermals . . .

Rudder only would be very authentic, but I would strongly suggest rudder/elevator as this will give a much broader performance envelope and enable it to be flown easily in more breeze. It will also make for better, higher launches on the line or hi-start and easier landings. So, unless you are aiming for total vintage authenticity (in which case you should really use a rubber driven actuator!), rudder/elevator will definitely produce a more practical, flyable, model.

Hi Owl - looks like great minds think alike! So do idiots, I suppose, but we'll scrub around that one

Thanks for the input. Rudder/elevator it is. I've also found the Selig/Donovan 7037 airfoil in Compufoil, and will use it. I can't figure out how to export it from Compufoil to here, however, so you'll just have to take my word for it!

Got the tail lamination form cut out.

Fin/rudder lamination

It has a slightly enlarged dorsal fin, a large, canted rudder, and an additional 3.5cm overall length.

Nice work with the bamboo skewers, Randy! If I tried that I'd get skewered.

The Goose is put away until I get my big building space in the barn done. It's too big to work on without damaging this or that in my temporary space.

Between "Honey Do-s" I've managed to get a bit more on Sinbad's progeny. Amidst all the clutter and chaos a little bitty birdie is emerging.

Looks good. I love the curves. The rudder hinge line looks like an Avro Anson.
