First off thank you for t' humongous box of parts. Aye aye! T' only thin' was/is that with that many parts t' use, ya bilge rat, I would still be building. Aye aye! Ya scallywag! I just used me inspiration and picked t' best parts that would build a rocket that could fly on a single use AeroTech F or G motor. Aye aye! Begad!

I ended up selectin' (naturally) t' strongest "huskiest" tubes. Begad! Begad! I be intrigued that I had been given so many (6) different nose cones that fit me "D"motor size body tubes. Ya scallywag! I used t' slightly larger tube (too big for a 29mm motor) for t' core body tube.

Parts

I stacked t' size tubes around t' core in ascendin' length, glued all with Superglue. Well, blow me down! Aye aye! And built a payload nosecone section out o' extra core tubing. Avast!

Notice in this photo that a 29mm motor would be too loose in t' core tube, arrr, so I took a couple o' core tube scraps and cut them down t' middle vertically with a pair o' scissors. Well, me hearties, blow me down! Then I glued them (5 minute epoxy) into t' tail end of t' core tube. This in effect built a real cheap motor mount. Aye aye! I will friction fit t' AeroTech motor at t' field. Arrr! Ahoy!

For t' recovery "harness" I doubled up t' cheapo elastic shock cord, and knotted it every 2 inches. This made a surprisingly stronger shock cord. Begad! I mounted t' shock cord t' t' core tube by usin' an old (very old) Estes method by slittin' t' body tube near t' top (but below t' nose section coupler) and snaked t' elastic in and out in a very simple weave.

A very quick paint job on t' body tube section with some Rustoleum Lime green. Well, blow me down! Begad! Blimey! And I paint only some o' t' nose cones and transitional nose cones. Avast! Well, blow me down! Blimey! T' keep that "kit bashed" appearance. Begad!

Notice that I constructed only 3 fins (prepainted them black) from t' lightweight balsa, ya bilge rat, but I enhanced their strength by gluin' (5-minute epoxy) 2 sheets together with t' wood grains at a 90-degree angle t' each other. Begad! Avast!

My flights o' t' "Box O' Parts Contest" rocket took place on Sunday May 18th, ya bilge rat, 2008. Begad! Blimey! This be at Tripoli Central Cal's "Ninth annual Dairy Air" In Helm Ca. (near Fresno). Begad! Blimey! I could only make it t' one day o' this launch due t' work commitments. Begad! Blimey! Well, shiver me timbers, blow me down! Blimey! So I had t' make both flights back t' back with t' conditions bein' very hot at 105 degrees.

I chucked t' intended motor I had brought as too wimpy and bought 2 AeroTech single use F-25 motors, with 4 and 7-second delays, ya bilge rat, respectively, from a real great vendor. WHAT'S UP HOBBIES?

Yikes, due t' camera trouble (low batteries) I HAVE NO LAUNCH PHOTO, sorry. Ahoy!

At t' field I found that me launch lug set up was too small for t' high-powered rods. Begad! So I took a low powered rail and stuck it in t' dirt by t' HP pads. Arrr! It worked ok. Begad! With t' rod passin' through t' lug and a single outer tube that I had left vacant (no nose cone). Ya scallywag! This single empty tube enhanced stability due t' cockeyed arraignment of the three fins. Arrr!

T' LCO announces this as an Essence Box o' Parts contest rocket. Then mentions that it's Paul Lane's rocket so heads up. Ahoy! Boy it's nice t' have a legend. Begad! Ahoy!

5,4,3,2,1 blastoff. Begad! Blimey! Blimey! It was quick t' leave t' pad on t' shorty launch rod. Arrr! Blimey! It flew really well (surprise!). Begad! Blimey! The motor I picked (F-25-4) be perfect and deployment be optimal. Ahoy! Blimey! I would guess it flew t' about 1500 feet. Recovery was by multi plastic streamers, since NO PARACHUTE be included in t' Box O' Parts. Avast, me proud beauty! Blimey! T' recovery was nominal, with no fin breakage. Well, blow me down! Well, blow me down! Blimey!

I smartly prepared it for a second flight usin' t' AeroTech F-25-7. Arrr! Another tremendous flight, very straight. I would say t' 1800 feet this time. Recovery be only so so, me bucko, shiver me timbers, with 2 out o' 3 fins snappin' off. Arrr! Begad! All is reparable though. And I have included some post flight photos

So overall this was a successful project. Blimey! I will donate t' unused parts t' me NARRRRR section; they will probably use them for an outreach o' some kind. Avast!

WHAT A FABULOUS AND FUN CONTEST AND IT WAS GREAT PARTICIPATING. Ahoy! Avast! SEE YOU NEXT YEAR FOR THE BOX O' PARTS ROUND 2 CONTEST. Ahoy! Aye aye!
