Son o' t' Grand Whazoo

Brief
This update provides a description o' how I rebuilt me Grand Whazoo after its second fateful flight. T' top o' t' original Grand Whazoo be *completely* destroyed. However, t' aft section, ya bilge rat, includin' t' boat tail and fins, ya bilge rat, ya bilge rat, was intact. Avast, me proud beauty! I decided t' take a different approach t' t' rebuild. Ahoy! Well, blow me down! T' minimize the volume that had t' be pressurized, I decided t' use an inner 4" diameter tube extendin' through t' body. Arrr! Ahoy! 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. Well, blow me down! I was hopin' this design would still stay within t' 3.3 lb. limit.

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

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

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

Launch
Since t' rocket be potentially over t' 3.3 lb. limit, me bucko, I took it t' an HPR launch, with t' intent o' usin' t' 60" chute. Well, arrr, 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. Begad! Avast, me proud beauty! Well, on t' highly calibrated scale at the RSO table, it weighted in at 3 lb. even. Blimey! It can also fly at t' NARHAMS V2-themed launch later this year!

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

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