Rocket PicBrief:
This is one of Estes 2001 new release kits. It is a skill level 2 sport rocket with parachute recovery.

Construction:
The kit comes with a body tube, upper body tube, adaptor, launch lug, nose cone, motor mount, die cut fin sheets, shock cord, assembled 12 inch parachute and decals.

PROS: Easy and rapid construction.

CONS: Beginners could run into problems with fin alignment.

This kit is easy to build but should be built by individuals with some modeling experience.

Like most Estes kits, the assembly starts with with the motor mount. I built this according to the instructions.

I then cut out the lower and upper tube marking guides and marked the fin and and launch lug aligning lines.

I now glued the tube adaptor into one end of the upper tube. After the glue dried on the nose cone insert, I glued it into the remaining open end of the tube.

After sanding the sheets smooth, I then carefully cut out each set of fins. You should have three lower and three upper fins for a total of six. After stack sanding, I then sanded the trailing and leading edges round.

This is where beginners could run into trouble. This rocket does not have a slotted tube and through the wall fins and the lower and upper fins have to be attached correctly for stable flights.

I then attached the fins one at a time. Estes recommends applying a thin layer of glue to the root edge of each fin, let it dry for one minute and then apply another film of glue then attach. I did this and it really does work. The fins grabbed quickly and tightly each time. After all the lower and upper fins were applied, I used a plastic 12 inch ruler to make sure that all the fins were in line.

I now cut out the shock cord mount from the instructions and assembled it. When the glue dried, I then mounted it about one inch from the top of the body tube.

I then applied the launch lug at this time. After that, I applied two glue fillets to each fin and the launch lug.

The instructions call for the parachute to be installed at this time but I prefer to do it when the rocket is finished.

Finishing:
PROS: Finished product looks sharp.

CONS: The trim schemes shown on the front panel should be decals instead of having to be painted. This could be another problem for beginners.

For finishing, I used Ace hardware brand white primer with Krylon Shortcuts Ocean Blue for the trim and NOW brand Royal Blue for the body and Gloss white for the fins. For those not familiar with this brand of paint, it can usually be purchased from Ace hardware stores for about $1.69 a can. It works very well and dries quickly.

I started by spraying the whole rocket with white primer. I then applied gloss white to the fins and let it dry. After that dried, I masked off the white areas of the fins for the Ocean Blue trim. I also painted the upper fins this color. I then masked off the upper fins and light blue trim areas and painted the remainder of the rocket Royal Blue. I then removed all masking tape. I then applied the white name decal. After that, I applied Krylon Gloss Clear enamel to protect the finish.

Construction Rating: 3 ½ out of 5

LaunchFlight:
PROS: Easy prep, excellent flight performance.

CONS: None found.

Recommended motors for this rocket are the A8-3 B4-4 B6-4 (first flight) C6-5.

This rocket does require recovery wadding and is packed in the normal fashion. The clip holds the motor in place. Make sure to align the top fins with the bottom fins.

I have flown this rocket twice. I decided to use an A8-3 and was not very impressed. I estimated an altitude of about 150 feet. The rocket did go straight however.

The next flight on a B6-4 was much better. The rocket flew straight to an estimated altitude of about 350 feet. I have yet to fly this rocket on a C6-5. I may use a C6-7 instead.

Recovery:
PROS: Rocket comes down nice on the provided chute.

CONS: Shock cord is too short.

The first unimpressive flight actually had a perfect recovery.

The next recovery did not go as well. When the ejection charge fired, it burnt a few shroud lines in half and ripped the canopy in a few places. The rocket came down a little fast but sustained no damage. I will install a new parachute as soon as possible. I am starting to hate plastic chutes.

Flight Rating: 4 out of 5

Summary:
Main PROS: Easy construction, distinctive appearance, excellent flight performance.

Main CONS: Fin alignment issues, shock cord too short, no trim decals provided.

Overall Rating: 4 out of 5

[Submit your Opinion]

GUEST's OPINION:
01/06 - "When I bought this rocket I assembled it in very little time, and flew it just twice on B6-4s. For a few years it has resided in the garage (law school work has got the better of me). I dug it up a few days ago and have bought a load of C motors. I will definitely be fitting a longer shock cord as others have recommended - that should stave off the nasty dent caused by the nose cone punching into the body tube. Wish me luck!" (N.O.)

GUEST's OPINION:
04/04 - "This has been one of the best flying rockets in my collection. It flies absolutely arrow straight. Unfortunately, I lost mine in a tree today (4/19/2004). I'm definitely going to pick up another one. Mine was painted monochromatic bright red. Looked pretty sharp with the white sticker. Terrific flights on C6-5s. I would like to upscale this one some day." (E.M.)

GUEST's OPINION:
07/03 - "This is a sweet-looking rocket. I painted mine with a triple coat of black, green sparkles and clear coat. Looks like James Bond weapon. Very consistent and impressive flights on B motors. A real sparkplug on Cís." (J.F.)

[Enter Rocket Specific Tip]

SPECIFIC ROCKET TIP:
10/03 - "The first ting I did was replace the original shock cord system with a Kevlar/elastic set-up. This pretty much is a good mod for almost any of the ESTES sport rockets and greatly extends the life of the recovery system. The decals are not to bad in this kit but to extend the life of them you can give the rocket a coat of "Future" floor polish to help seal them and give the finished rocket a nice high gloss! Mix a ratio of 1 part water and 2 parts floor polish and paint on with a foam brush. Let drip dry over a few sheets of newspaper." (J.R. )

SPECIFIC ROCKET TIP:
09/03 - "I noticed that if your fins are not straight (like mine) the rocket tends to spin near apogee like mine did. So as your letting your fins dry with epoxy , make sure you keep an eye on them incase they try to lean to a side. But on the long run this is a really impressive kit." (K.H )

12-13-2003 Karl Houghton Est SU C6-5 None - Unknown 5-10 mph winds RIP - Left the rod,span like a bat out of hell!lawn darted under force from a C6 ! Nosecone came away from small carboard payload.This is the first time this has ever happend! Status: Lawn Dart
02-05-2006 Geoffrey Kerbel Est SU B6-4 Apogee - NC Up
(400' or so ft)
0-5 mph winds Event: Local park
Night lite - Ugly rocket from Ebay but flies great! New shock cord and chute. Good flight and landing.
10-28-2006 Geoffrey Kerbel Est SU B6-4 Didn't See Calm Event: GHS launch

10-28-2006 Geoffrey Kerbel Est SU C6-5 Didn't See Calm Event: GHS launch
Night lite - Still visiable way up there on night launch. Cool effect to watch rockets go up at night. Blinking light works like a charm. Visiable all the way up and down. Actually easier to find once it is on the ground!
02-24-2007 Geoffrey Kerbel Est SU C6-5 Didn't See Calm Event: ARG-4
Night lite - Stock Estes kit modified for night launch. Added clear payload section with a small strobe light inside. Works great and can be seen all the way up and down just fine. Close recovery this time.

06-07-2003 Johnny Rocket Est SU B6-4 Very Early Calm - On launch, this rocket caught on the launch rod and started taking the pad up. The rocket then broke loose at 60 deg. angle, arced, then popped chute about 35 feet altitude. Whew, recovered ~45 yds away.
06-07-2003 Johnny Rocket Est SU C6-5 Didn't See Calm - Great Lauch. I am very happy with this rocket, it's my favorite to launch. Strait and true. Very high on C, came down slow, great hang time, no damage, recovered 80 yds from launch pad.
08-28-2002 John Rowan-Stern Est SU A8-3 Very Late 0-5 mph winds - To much tilt in launch rod and not enough motor. Almost drilled it into the sod. Ejected in the nick of time. No damage, full recovery
09-04-2002 John Rowan-Stern Est SU A8-3 Apogee - NC Down 5-10 mph winds - Weathercocked almost horizontal at about 100'. Ejection at 70'. Crimped the BT a little but still flyable.

04-01-2003 John Rowan-Stern Est SU B6-4 Apogee - NC Down 0-5 mph winds - 18 mylar and Nomex heat shield test flight. Slight tangling of heat shield but other than that OK flight
04-01-2003 John Rowan-Stern Est SU B6-4 Apogee - Perfect 0-5 mph winds - 18 mylar test. Ok Flight
04-01-2003 John Rowan-Stern Est SU B6-4 Just Before 5-10 mph winds - 24 mylar chute test. Almost lost rocket in thermal. Great impulse and ejection. No damage, some wear is evident on BT from kevlar shock cord but will CA. Ok Flight.
04-01-2003 John Rowan-Stern Est SU C6-5 Apogee - NC Down 5-10 mph winds - 18mylar and heat sheild test. Perfect impulse and good ejection. Heat shield worked perfectly after adjustment! Slight crisping of shield but definitely re-usable! Ok Flight.
