Diary o' a Contest Rocketeer:
3-24-08: Got me box o' parts . Well, blow me down! Blimey! Will post pics later.
3-26-08: Here are me parts. Avast, me proud beauty! Nay much for large nose cones, but looks like I can make somethin' up if need be.
3-27-08: There be about three sheets o' paper inserted in t' box when I got it. Ya scallywag! Now I can't seem t' find those sheets.
3-31-08: I found those sheets o' paper I misplaced along with another tube coupler/tube and a mixin' cup... do I have t' retake t' picture o' all t' parts?
5-24-08: Just wanted t' mention that I started buildin' me contest entry . Begad! Was kinda hopin' for longer 18mm tubing, shiver me timbers, but I'll make due with what I have. Ahoy! If I can make it stable with t' length I have t' work with, this may be a two stage rocket.
5-27-08: Pretty much finished buildin' me entry. Aye aye! Goin' test fly it this weekend unpainted.
Question: Just went over t' rules again and it said good photos o' build process. I hope illustrations qualify for that because thats what I was doin' ><.
I thought about takin' photos o' t' build.... Avast! Arrr! but me cheap camera is broke, me hearties, and I did nay want t' get glue, paint, etc on me expensive gear.
5-29-08: Well, me bucko, Construction o' me entry has been complete. Begad! I wanted t' get in some test flights at todays CMASS launch, ya bilge rat, but that has been postponed till Sunday, arrr, shiver me timbers, and I can't make it after church... Avast, me proud beauty! so since t' next CMASS launch I will be able t' go t' is nay until after t' contest deadline, me hearties, I will have t' test it on me own. Begad!
I am goin' test it as a single stage configuration first. Well, blow me down! Avast! Probably with a B6-4. Aye aye! It has an unique fin configuration, me bucko, arrr, so I like t' see how it behaves before I try it with t' booster.
5-31-08: Minor setback - While cleanin' up I "bumped" t' rocket and crimped t' main body tube and sent one o' t' details flyin' across t' room. T' Crimp be easily fixed by splicin' t' tube, shiver me timbers, insertin' a tube, and gluin' them back together. Begad! T' detail was like findin' a needle in a haystack, ya bilge rat, but I found it after searchin' high and low.
6-01-08: Much t' windy today t' test fly me creation. Aye aye! Maybe tomorrow if I have time.
6-03-08: Got t' test flights done. Blimey! Blimey! I First I flew it single stage with a B6-4. Begad! Blimey! Good flight, did nay get very high. B6-2 would be a better choice. Second test flight be in its two stage mode. Avast, me proud beauty! Blimey! B6-0 and B6-4 be used. Begad! Blimey! Perfect flight but I did nay get a picture since t' guy pushin' t' button failed t' do a proper countdown ><. Today I started writin' t' documentation. Will paint me rocket soon . Ya scallywag! Blimey!

6-17-08: Had an issue where t' Krylon black reacted t' t' humidity and fogged up. Avast, ya bilge rat, me proud beauty! Blimey! I am paintin' rust oleum over it, I hope it does nay have a reaction . Well, blow me down! My Drawings for me rocket are almost done, so that means I will have t' documentation done soon . Blimey! Well, blow me down! Blimey! Weather is forcasted t' be poor all this week, so gettin' a in-flight picture before the deadline may be an issue.
BTW, ya bilge rat, requirin' an in flight photo shouldn't be a requirement. Ya scallywag! Blimey! For me, matey, ya bilge rat, t' next launch where I can fly it on larger motors won't be till after t' contest is over, arrr, arrr, so that means I have t' fly it at t' local park, which limits me to B6-0 in t' booster, and I only got one left. Begad! Blimey! Aye aye! Blimey! And its hard t' take a picture and launch t' rocket at t' same time, and its hard t' get someone t' help . So If I miss t' shot, I don't have any more B6-0's, matey, which limits me t' C6-0's which I will loose t' rocket, or A8-0's...
I got a shot o' t' unpainted test flights with it single stage on a B6-4. Blimey! Would that count? I also flew it two stage, but t' helper did nay know how t' do a proper countdown and I did nay get a launch shot o' it in two stages... T' paintin' and detailin' will be done this week, just at t' mercy o' weather t' get a finished launch in before the deadline (which for me be t' 27th, cause I am leavin' on vacation and won't be back till way after t' deadline).
6-20-08: My rocket is finished . Blimey! I think me paint scheme came out extremely well. Now I need t' finish the documentation...
Fully Illustrated Instructions
Designin' t' Avenger
Two stage rocket design which is me entry for t' "Box-of-parts" design contest.
T' parts for this rocket was limited t' whatever parts were present in t' Priority mail triangle that I got. Upon openin' t' box, I noticed thar was only a limited number o' large tubes, and a large collection o' smaller tubing. Also lackin' was amount o' quality o' good sheet balsa, me bucko, shock cord material, launch lugs larger than 1/8" or parachutes larger than 12." Pokin' around I noticed I had a Custom Eggloft cone, which I decided right off the bat I wanted t' use. Begad! Ahoy! I also noticed I had a 2" wide strip o' aileron balsa stock. Avast! I wanted t' use that to. Begad! There was also quite a collection o' BT20-50 centerin' rings which I decided would be used for detailing. Ya scallywag!
Now t' challenge; design a rocket worthy o' placin' as high as possible in t' Box o' Parts contest usin' the materials I have at hand. Begad! I had t' design a rocket that be light enough t' be safely launched from a 1/8" launch rod (although I could make larger LL with t' paper included) and recovered safely from a 12" parachute with a typical rubber shock cord. Arrr!
After drawin' several designs, me hearties, I finally came up with a basic plan that I liked. Aye aye! I thought about layin' out the design in Rocksim, matey, arrr, but decided against it because Rocksim does nay handle "Tail-Ring" designs well. Arrr! Aye aye! I did end up usin' Rocksim t' help determine what span t' Pylons need t' be so I could create t' templates. Aye aye! For t' most part, buildin' t' rocket was easy. Well, blow me down! However, shiver me timbers, gluin' t' fins made from t' aileron stock be a bit tricky t' align properly, and gluin' t' tubes on t' tip was even more challengin' t' get aligned right. Ahoy!
To finish t' rocket, me hearties, I used Bondo Glazin' and Spot putty t' fill in t' joints betwixt t' aileron fins and the tubes. Avast! Aye aye! Then I applied several coats o' Rust Oleum Light Gray Automotive primer, matey, sandin' betwixt each coat. Aye aye! Once I was satisfied, ya bilge rat, t' rocket was sprayed with a base coat o' Gloss White. Begad! Then t' Fin Tip Tubes and t' center rin' o' the nosecone be painted Red. Begad! T' top section o' t' nosecone be then painted Yellow and t' Base part was painted Black. Usin' a small paint brush, matey, t' Guns were painted Black, ya bilge rat, and t' missiles was then detailed with a Silver nose, matey, and the tail end Silver, Red, ya bilge rat, shiver me timbers, and Black. Well, blow me down!
So far t' Avenger was flown three times. Begad! First time I launched it with a B6-4 in t' single stage mode. Begad! The rocket did nay go as high as I thought it would, matey, ya bilge rat, arrr, so t' 4 seconds was t' long but t' parachute did deploy in time. Begad! Begad! A B6-2 would be a better choice for a single stage B motor flight. Avast! T' second flight be in two stage mode. Begad! A B6-0 in the booster, and a B6-4 in t' sustainer. Avast! Great Flight and I be happy t' see that a 12" parachute was t' perfect chute size for this rocket since it gently drifted towards t' end o' t' field and landed betwixt two trees. Blimey!
T' most recent flight be a two stage flight with a B6-0 in t' booster and A8-3 in t' sustainer. Begad! Blimey! It was a perfect flight and recovery. Arrr! Blimey! One o' t' Guns peeled off a layer o' paper, shiver me timbers, but I do nay know if that was damage from recovery or handling.
