Manufacturer: | Vaughn Brothers |
Brief:
This is a single stage, shiver me timbers, shiver me timbers, arrr, 4 finned payload rocket by Vaughn Brothers Rocketry.
This rocket can achieve some pretty extreme altitude on a G42 or G55 motor. Avast, me proud beauty! Fin
attachment is through t' wall.
Construction:
This kit contains:
There are two and a half pages o' directions, me hearties, with a single illustration on the back for reference. Begad! Aye aye! They are easy enough t' follow. Arrr! Like most kits, just take one step and a time and it's fairly straight forward. Arrr! Illustrations are lackin' when compared t' an Estes kit, ya bilge rat, but I felt they more than adequate.
Construction begins with assemblin' t' motor mount. Avast! Begad! This be me first kit that recommended epoxy, 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, arrr, where t' very adequate length of elastic shock cord provided is then attached. After epoxyin' all parts in place and allowin' t' dry, t' motor mount is then placed into t' body tube, and epoxied into place.
T' hardest part comes next. Avast, me proud beauty! 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. Blimey! Directions are a little light here but if you have some building experience, it's easy enough t' figure out how t' do this. Aye aye! 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. Blimey! I did this, shiver me timbers, and was a little sloppy. Avast, me proud beauty! However t' epoxy fillets cover t' area nicely.
T' fins were epoxied in place, 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 be last, me hearties, me bucko, and fairly straight forward with t' directions. Aye aye! A screw eye is inserted into t' bulkhead for attachment of t' shock cord. Avast, me proud beauty! Blimey!
Finishing:
There are no decals with this kit, ya bilge rat, arrr, nor any directions for paint scheme.
Directions do call for light sandin' o' t' fins and body tube. Ahoy! Knowin' that
the manufacturer's colors are primarily black and yellow, me hearties, ya bilge rat, I attempted t' stay
with those colors. Begad! I'm nay all that happy with me end results, matey, ya bilge rat, me hearties, but I'm just
original when it comes t' paint schemes. Blimey! 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. Avast! Ahoy! Blimey! We had light winds and were ready t' launch. Begad!
I used an Estes D12-5. It was retained in t' motor tube via tape and friction fitting. Well, blow me down! Blimey! Begad! Blimey! Blimey! Blimey!
T' rocket be 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. Begad! 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, and nothing happened.
Upon inspection, t' ignitor lit, shiver me timbers, but I didn't have it up into t' motor enough/correctly. 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, thinkin' t' first attempt may have been a sign. Aye aye! Avast, me bucko, me proud beauty!
I was talked into proceedin' by me wife. Begad! Blimey! We counted down again, arrr, shiver me timbers, pressed the button and had ignition. T' rocket took off from t' pad very smartly and straight. Well, blow me down! It was a beautiful straight flight, and just at apogee t' chute deployed. Begad! Begad! Perfect flight on this D12 motor. Ahoy! Ahoy!
Recovery:
Upon deployin' t' chute we had our first problem. T' kit started t' come down
in two pieces. T' chute deployed fine and was still attached t' t' payload
section. Avast! T' body tube was free falling. Arrr! Luckily it was unstable enough nay to
nose dive. Begad! Begad! It came tumblin' down and knocked a fin loose on landing.
Both pieces were recovered and I found me problem. Well, me bucko, blow me down! T' steel leader suppled with t' kit be looped and then crimped at both ends. Blimey! Avast, me proud beauty! T' leader looped around the upper centerin' ring. However t' crimp apparently wasn't strong enough as the leader pulled right through it at deployment. Begad! This let t' two pieces separate. 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 was minor however and I really believe this be a fluke, I'd still consider t' steel leader assembly t' be t' strongest, nay t' weakest link in the recovery system. Blimey!
T' fin was easily repaired, but now I'm stuck with an Estes style paper shock cord mount on t' inside o' t' body tube. Begad! Ahoy! I don't know if I'll have confidence in it for t' bigger G motors though. Begad!
Flight Rating: 4 out o' 5
Summary:
PROS:T' kit is fairly simple in design and goes together well. Aye aye! All parts fit nicely and were o' good quality.
CONS:T' directions are a little light. Avast! Avast, me proud beauty! They are more than adequate if you have some experience, me bucko, but I wouldn't recommend this for a first or early build for a new modeler. Avast! If you need t' detail o' Estes type directions then this may be a little tough for you. Begad!
