NEW IN BOX, Rotax 503 DCDI Engine, Complete!NEW IN BOX, Ultralight sails, Complete!NEW, 6061-T6 anodized aluminum tubing, 56 (fifty-six) 12-foot tubesUSED, Misc Parts, Wheels and BrakesExtras!Complete Engine kit: Rotax 503 Dual Carb / Dual Ignition, oil injection, B gearbox (2.58:1), pull start, crankcase date says "3/03/08", s/n M5766914, includes three-piece exhaust assembly with exhaust temperature ports, two Bing 54 carbs*, gaskets, boots, fuel pump, spark plugs, prop flange, tools and misc hardware.*I actually have FOUR brand-new Bing 54 carbs, two have lever choke, two have cable choke.  You can choose the two carbs you want.Complete Sail kit: Ultralight sails from Great Salt Lake Sails.  The set includes two wings, two ailerons, two flaps, two vertical stablizers, two horizontal stabilizers, two elevators, one rudder.These skins match a prototype ultralight from circa 1980 called a "Sidewinder".  The Sidewinder is very similar to a Phantom Classic, except that the Sidewinder has flaps whereas the Phantom does not.  The Sidewinder prototype later became the Spitfire-I ultralight.From 2000 to 2011 I owned what I believe was the last remaining of three Sidewinder prototypes.  There are no plans that I'm aware of for building the frames.  I may be able to find and contact the current Sidewinder owner.  If you'd like to meet with him to take measurements I will try to arrange it -- no guarantees he or the aircraft is still around.  Otherwise, you're on your own making frames.  This is a real do-it-yourself project.Tubing: Fifty-six 12-foot tubes, clear anodized 6061-T6 aluminum(15)   1/2" x 0.049" (one-half inch O.D.) ** (2)   7/8" x 0.049" (seven-eigths inch O.D.)(15)     1" x 0.049" (one inch O.D.) (6)     1" x 0.065" (one inch O.D.) *** (6) 1 5/8" x 0.049" (one and five-eights inch O.D.)(12) 1 3/4" x 0.049" (one and three-quarters inch O.D.)** The 1/2" tubing was intended to be the wing ribs.  I bought the plastic spoons and saddles that go into the ends of the tubes, only to find out I ordered tubing that was too thick. (The I.D. is too small to insert the fittings).  The tubing can be used as-is without the fittings, although you'll need to flatten and smooth out the ends of the tubes so they don't tear through the sails.  Or you can order new 1/2" tubing and use these tubes for general structural purposes.*** these tubes with the heavier wall thickness are for the wing compression struts.There should be enough aluminum to make all of the wings and control surfaces.  I also think there's enough to make the wing (main) struts and some of the fuselage down-tubes, but there's no main boom, nor main gear spar, nor fuselage bottom tubes, etc.Misc USED Parts:  Two main gear assemblies with drum brakes, one steerable nose gear assembly, two hydraulic disk calipers from a SkyRanger, one additional tire and rim.Bonus Stuff included!  (I will throw in some other brand-new parts, about $200 worth).This package of equipment and parts would likely cost you over $12,000.00 if you were to shop around and collect all of the components individually.  And having the aluminum tubing anodized is a separate step!  You'll need to find a shop that can do it.As far as delivery, you can come pick up the parts or arrange delivery yourself.  You might need a flatbed.  I'm located north of Houston, TX.  I will consider dropping the parts off within about 250 miles of my location (provided I can rig up a carrier for the tubing to fit in my 8-ft pickup bed -- can't have those tubes bangin' and clangin' around!)  That will cover pretty much all of S.E. Texas and western Louisiana.I would rather sell all of these parts together.  If I'm unsuccessful I will consider selling the items separately.  You may have to wait a couple of months for me to decide.UPDATE, I posted an old pic of me flying the Sidewinder.
