Rocket PicBrief:
This is a single stage, 4 finned payload rocket by Vaughn Brothers Rocketry. This rocket can achieve some pretty extreme altitude on a G42 or G55 motor. Avast! Fin attachment is through t' wall.

Construction:
This kit contains:

  • 2 body tubes, me bucko, one for t' payload section and one for t' booster
  • 2 Estes cardboard style centerin' rings
  • 4 fiberglass fins
  • Plastic nose cone
  • A nice steel leader type attachment for t' shock cord
  • A nice nylon 18" parachute

There are two and a half pages o' directions, with a single illustration on the back for reference. They are easy enough t' follow. Like most kits, me bucko, just take one step and a time and it's fairly straight forward. Illustrations are lackin' when compared t' an Estes kit, but I felt they more than adequate.

Construction begins with assemblin' t' motor mount. Begad! This was me first kit that recommended epoxy, me bucko, and t' recommendations were either 5 or 30 minute epoxy. I assembled this kit with 5 minute epoxy.

T' top centerin' rin' has a steel leader already attached. Aye aye! Blimey! This steel leader extends out t' top o' t' body tube, where t' very adequate length of elastic shock cord provided is then attached. Begad! After epoxyin' all parts in place and allowin' t' dry, me bucko, t' motor mount is then placed into t' body tube, and epoxied into place.

T' hardest part comes next. Well, blow me down! Ahoy! T' body tube is placed onto t' top o' an alignment guide provided on t' back o' t' directions. Fin locations are then marked. Directions are a little light here but if you have some building experience, it's easy enough t' figure out how t' do this. 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. Aye aye! I did this, and was a little sloppy. Aye aye! However t' epoxy fillets cover t' area nicely.

T' fins were epoxied in place, me hearties, 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 was added next without any problem.

T' coupler and bulkhead assembly was last, me bucko, me hearties, arrr, and fairly straight forward with t' directions. Begad! Avast, me proud beauty! A screw eye is inserted into t' bulkhead for attachment of t' shock cord. Begad!

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. Begad! Knowin' that the manufacturer's colors are primarily black and yellow, matey, I attempted t' stay with those colors. Begad! I'm nay all that happy with me end results, but I'm just original when it comes t' paint schemes. Avast, me proud beauty! Avast! Nothin' t' do with t' kit itself.

T' manufacturer lists a finished weight o' 4.2 ounces, arrr, and mine came in just under at 4.0 ounces.

Construction Rating: 4 out o' 5

Flight:
Our first flight was on 2-19-03. We had light winds and were ready t' launch. Blimey! Blimey!

I used an Estes D12-5. Begad! Begad! It be retained in t' motor tube via tape and friction fitting. Begad! Begad!

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. I elected t' use it instead o' t' 18", arrr, 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, shiver me timbers, arrr, me hearties, 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. However believin' in t' rocketry version o' Murphy's law I began to wonder about launching, me hearties, ya bilge rat, thinkin' t' first attempt may have been a sign. Avast!

I be talked into proceedin' by me wife. Begad! Arrr! We counted down again, pressed the button and had ignition. Ahoy! Well, blow me down! T' rocket took off from t' pad very smartly and straight. It was a beautiful straight flight, and just at apogee t' chute deployed. Perfect flight on this D12 motor. Arrr! Avast, me proud beauty!

Recovery:
Upon deployin' t' chute we had our first problem. Well, blow me down! T' kit started t' come down in two pieces. Avast! T' chute deployed fine and was still attached t' t' payload section. Blimey! T' body tube was free falling. Luckily it was unstable enough nay to nose dive. Aye aye! It came tumblin' down and knocked a fin loose on landing.

Both pieces were recovered and I found me problem. Ya scallywag! Blimey! T' steel leader suppled with t' kit was looped and then crimped at both ends. Aye aye! Blimey! T' leader looped around the upper centerin' ring. Avast, me proud beauty! Blimey! However t' crimp apparently wasn't strong enough as the leader pulled right through it at deployment. Begad! Blimey! This let t' two pieces separate. Avast, me proud beauty! Blimey! Well, blow me down! Blimey! T' leader came already in place around t' centerin' ring. Aye aye! Blimey! Arrr! Blimey! 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 was a fluke, ya bilge rat, I'd still consider t' steel leader assembly t' be t' strongest, nay t' weakest link in the recovery system. Well, blow me down! Begad!

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. Ahoy! I don't know if I'll have confidence in it for t' bigger G motors though.

Flight Rating: 4 out o' 5

Summary:

PROS:T' kit is fairly simple in design and goes together well. Blimey! All parts fit nicely and were o' good quality.

CONS:T' directions are a little light. Well, blow me down! They are more than adequate if you have some experience, matey, ya bilge rat, but I wouldn't recommend this for a first or early build for a new modeler. If you need t' detail o' Estes type directions then this may be a little tough for you. Arrr!
