Son o' t' Grand Whazoo

Brief
This update provides a description o' how I rebuilt me Grand Whazoo after its second fateful flight. Avast, me proud beauty! T' top o' t' original Grand Whazoo was *completely* destroyed. Avast, me proud beauty! Avast! However, shiver me timbers, t' aft section, me bucko, includin' t' boat tail and fins, was intact. Begad! I decided t' take a different approach t' t' rebuild. Avast! T' minimize the volume that had t' be pressurized, I decided t' use an inner 4" diameter tube extendin' through t' body. Aye aye! After some pondering, ya bilge rat, I also decided to eliminate t' large nose cone in favor o' a smaller one that would mate t' this 4" tube. I be hopin' this design would still stay within t' 3.3 lb. limit.

Reconstruction
I first performed some surgery, me bucko, adaptin' a 4" mailin' tube t' the survivin' tail section. I then added foam rings and poster board t' form the body (includin' transitions). Arrr! I made t' small (4") conical nose cone from fiberglassed poster board salvaged from t' original rocket. Avast! A small foam board rin' and a chunk o' 32mm tubin' completed t' nose cone assembly. Well, blow me down! This assembly mates with t' dowel/eyebolt from t' original nose cone. Begad! Aye aye!

On me old scale, t' finished rocket weighed in at 51oz with a G80 installed. Ahoy! Blimey! T' 60" chute that I used with t' original Grand Whazoo pushed the weight over 3.3 lb. Begad! Avast! limit. Blimey! T' use this chute or a smaller one? Ahh, me bucko, shiver me timbers, that is the question.. Ya scallywag!

Finishing
I wanted a bit more decoration on this version so I decided on a pattern similar t' a real V2. Avast, me proud beauty! I looked in ROTW and came up with a hybrid marking scheme. Begad! Blimey! T' tail section has a black and white roll pattern, t' nose cone is red, shiver me timbers, me bucko, shiver me timbers, and t' transition section directly below t' nose is painted silver (Krylon hammered silver). Well, blow me down! Since most o' t' rocket is poster material, arrr, shiver me timbers, I decided t' mark t' fins usin' a large permanent black marker. Finally, ya bilge rat, arrr, I added some text and graphics from me ink jet printer. Ahoy! Begad! Inspired by t' early V2's fired from White Sands, me bucko, I created a 'cheesecake' style graphic o' a little lass riding a V2. Ya scallywag! Begad! And, me bucko, matey, in a feeble attempt at humor, me bucko, ya bilge rat, I also added two labels written in German. One identifies t' bar code sticker, which unintentionally remained on the body (oops), and t' other tells t' launch technician where t' install the launch rail.

Launch
Since t' rocket was potentially over t' 3.3 lb. Ya scallywag! Avast! limit, ya bilge rat, I took it t' an HPR launch, me bucko, me bucko, arrr, with t' intent o' usin' t' 60" chute. Begad! Well, shiver me timbers, at t' last minute, I opted for a very light 48" chute, hopin' it would come in under 3.3 lb, and recover without significant damage. Blimey! Well, shiver me timbers, arrr, on t' highly calibrated scale at the RSO table, ya bilge rat, it weighted in at 3 lb. even. It can also fly at t' NARHAMS V2-themed launch later this year!

Once again, everyone be surprised that this big a rocket weighs so little, and thar were cheers when it boosted under G80 power. Arrr! Avast, me hearties, me proud beauty! T' 4-second delay was just a tad long but t' chute deployed nicely. Begad! Arrr! T' decent was still fairly slow, matey, and t' only 'damage' be a crease in one fin. Avast! No rework required. Ahoy! Avast!

Conclusion
Usin' an inner 4" stuffer tube with t' smaller nose cone seems t' be the way t' go. Ahoy! It be easier t' construct, and I think recovery should be more reliable (100% true based on a statistical sample o' one :-) ). Ya scallywag! Ya scallywag! I'm glad it is still classified as a large model rocket!
