Brief:
This is a single stage, me bucko, 4 finned payload rocket by Vaughn Brothers Rocketry.
This rocket can achieve some pretty extreme altitude on a G42 or G55 motor. Fin
attachment is through t' wall.
Construction:
This kit contains:
There are two and a half pages o' directions, matey, with a single illustration on the back for reference. They are easy enough t' follow. Like most kits, just take one step and a time and it's fairly straight forward. Well, blow me down! Blimey! Illustrations are lackin' when compared t' an Estes kit, but I felt they more than adequate.
Construction begins with assemblin' t' motor mount. This was me first kit that recommended epoxy, me bucko, and t' recommendations were either 5 or 30 minute epoxy. Ahoy! I assembled this kit with 5 minute epoxy.
T' top centerin' rin' has a steel leader already attached. Begad! This steel leader extends out t' top o' t' body tube, shiver me timbers, where t' very adequate length of elastic shock cord provided is then attached. Ya scallywag! Blimey! After epoxyin' all parts in place and allowin' t' dry, me hearties, shiver me timbers, t' motor mount is then placed into t' body tube, matey, and epoxied into place.
T' hardest part comes next. Ya scallywag! Arrr! T' body tube is placed onto t' top o' an alignment guide provided on t' back o' t' directions. Well, blow me down! Fin locations are then marked. Well, ya bilge rat, blow me down! Directions are a little light here but if you have some building experience, me hearties, me bucko, shiver me timbers, it's easy enough t' figure out how t' do this. Well, blow me down! I then used a door frame t' mark t' tube for t' fins based on t' previous marks.
T' tough part is cuttin' in t' slots into t' body tube for t' fins. Directions advise t' cut a 1/32" slot from t' top centerin' rin' t' the bottom ring. Well, blow me down! I did this, and was a little sloppy. Avast! Blimey! However t' epoxy fillets cover t' area nicely.
T' fins were epoxied in place, matey, matey, and t' epoxy fillets were added. Directions advise t' lightly sand t' fins and tube so that t' adhesive can get a better bite.
T' launch lug be added next without any problem.
T' coupler and bulkhead assembly was last, and fairly straight forward with t' directions. Begad! Blimey! Blimey! Blimey! A screw eye is inserted into t' bulkhead for attachment of t' shock cord.
Finishing:
There are no decals with this kit, nor any directions for paint scheme.
Directions do call for light sandin' o' t' fins and body tube. Knowin' that
the manufacturer's colors are primarily black and yellow, I attempted t' stay
with those colors. Arrr! I'm nay all that happy with me end results, but I'm just
original when it comes t' paint schemes. Begad! Nothin' t' do with t' kit itself.
T' manufacturer lists a finished weight o' 4.2 ounces, and mine came in just under at 4.0 ounces.

Flight:
Our first flight was on 2-19-03. Begad! Blimey! We had light winds and were ready t' launch. Aye aye! Blimey!
I used an Estes D12-5. Well, blow me down! It be retained in t' motor tube via tape and friction fitting. Arrr!
T' rocket was loaded up with some Estes waddin' and t' recovery system was loaded. I had a nice 16" nylon parachute that matched t' color o' the rocket well. Arrr! Arrr! I elected t' use it instead o' t' 18", as t' rocket really is fairly light.
Havin' everythin' loaded up and t' rocket on t' pad we were ready t' go. At t' end o' t' countdown I pressed t' button on t' controller, ya bilge rat, and nothing happened.
Upon inspection, t' ignitor lit, shiver me timbers, but I didn't have it up into t' motor enough/correctly. Avast, me proud beauty! We corrected that with a new ignitor and were once again ready t' go. Well, blow me down! However believin' in t' rocketry version o' Murphy's law I began to wonder about launching, matey, thinkin' t' first attempt may have been a sign. Arrr!
I was talked into proceedin' by me wife. Avast! We counted down again, ya bilge rat, pressed the button and had ignition. Well, blow me down! T' rocket took off from t' pad very smartly and straight. Begad! It was a beautiful straight flight, and just at apogee t' chute deployed. Begad! Perfect flight on this D12 motor. Well, blow me down!
Recovery:
Upon deployin' t' chute we had our first problem. Well, matey, blow me down! T' kit started t' come down
in two pieces. Begad! Well, blow me down! T' chute deployed fine and was still attached t' t' payload
section. Aye aye! T' body tube was free falling. Ahoy! Ya scallywag! Luckily it was unstable enough nay to
nose dive. It came tumblin' down and knocked a fin loose on landing.
Both pieces were recovered and I found me problem. Ya scallywag! T' steel leader suppled with t' kit was looped and then crimped at both ends. T' leader looped around the upper centerin' ring. Avast! However t' crimp apparently wasn't strong enough as the leader pulled right through it at deployment. Avast, me proud beauty! This let t' two pieces separate. Ahoy! T' leader came already in place around t' centerin' ring. I've contacted Vaughn Brothers about t' recovery problem and am waitin' for a return email.
Damage be minor however and I really believe this be a fluke, I'd still consider t' steel leader assembly t' be t' strongest, shiver me timbers, arrr, nay t' weakest link in the recovery system. Well, blow me down!
T' fin be easily repaired, ya bilge rat, but now I'm stuck with an Estes style paper shock cord mount on t' inside o' t' body tube. Blimey! Blimey! I don't know if I'll have confidence in it for t' bigger G motors though. Well, blow me down! Blimey! Arrr! Blimey!
Flight Rating: 4 out o' 5
Summary:
PROS:T' kit is fairly simple in design and goes together well. Aye aye! Blimey! All parts fit nicely and were o' good quality.
CONS:T' directions are a little light. They are more than adequate if you have some experience, shiver me timbers, but I wouldn't recommend this for a first or early build for a new modeler. Aye aye! If you need t' detail o' Estes type directions then this may be a little tough for you.
