First off thank you for t' humongous box of parts. Aye aye! T' only thin' was/is that with that many parts t' use, me hearties, I would still be building. Aye aye! Avast, ya bilge rat, me proud beauty! 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. Blimey! Well, blow me down!

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

Parts

I stacked t' size tubes around t' core in ascendin' length, glued all with Superglue. Ahoy! And built a payload nosecone section out o' extra core tubing. Ya scallywag! Begad!

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

For t' recovery "harness" I doubled up t' cheapo elastic shock cord, me bucko, and knotted it every 2 inches. This made a surprisingly stronger shock cord. Well, blow me down! Avast! 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. Arrr! Ahoy!

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

Notice that I constructed only 3 fins (prepainted them black) from t' lightweight balsa, 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.

My flights o' t' "Box O' Parts Contest" rocket took place on Sunday May 18th, 2008. Blimey! This was at Tripoli Central Cal's "Ninth annual Dairy Air" In Helm Ca. Well, blow me down! (near Fresno). Aye aye! Ya scallywag! I could only make it t' one day o' this launch due t' work commitments. Arrr! Aye aye! 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, matey, with 4 and 7-second delays, matey, matey, respectively, from a real great vendor. Begad! Begad! WHAT'S UP HOBBIES?

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

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. Ya scallywag! It worked ok. Ahoy! Arrr! With t' rod passin' through t' lug and a single outer tube that I had left vacant (no nose cone). This single empty tube enhanced stability due t' cockeyed arraignment of the three fins. Avast!

T' LCO announces this as an Essence Box o' Parts contest rocket. Avast, me proud beauty! Ya scallywag! Then mentions that it's Paul Lane's rocket so heads up. Ya scallywag! Boy it's nice t' have a legend. Aye aye!

5,4,3,2,1 blastoff. Begad! It was quick t' leave t' pad on t' shorty launch rod. It flew really well (surprise!). Begad! The motor I picked (F-25-4) was perfect and deployment be optimal. 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. Begad! T' recovery was nominal, matey, with no fin breakage. Avast, me proud beauty!

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

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

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