[Picture](02/28/98) Estes, the long time leader, has created a flying buddy for the Mosquito. . . Quark. Quark is mini-engine, featherweight, tumble recovery rocket that's simple and fun to fly.

The kit comes with 5 parts, instructions and decals. You will need a hobby knife, sandpaper and glue to assemble this kit. The instructions are straight forward and easy to follow.

Construction is simple and took less than one hour to build. The four fins are cut from two pieces of balsa strips. Once all cut, they need held together and sanded to make them all the same size. Then the leading and trailing edges will need rounding. Although there are many techniques for this, I simply lay a sheet of sandpaper on my work bench and stroke each edge the same number of strokes on each side. I find this nearly always brings the edges to a nice centered and rounded point. [Picture]

Once the fins are ready, construction is a snap, especially with the fast-drying action of CA. Four fins, a hollow, plastic nose cone and a launch lug . . . done. Made fin fillets with 5-minute epoxy, sealed the fins with a thin layer of epoxy, and this mini was ready for light sanding and painting.

I finished it with Plasti-Kote primer and some left over denim-colored enamel paint. There are seven decals, excluding the Estes logo, that are self adhesive. Be cautious of placement of the Quark name label. If too high on the body, the label will have creases in it due to the curvature of the nose cone.

When finished, my Quark stood a towering 5. 7", as opposed to the 5. 2" indicated in the catalog.

The Quark is a good and fast flyer with a tumble recovery. Be sure to designate a spotter (unlike myself), because it's small and very hard to tract. My first flight was on an 1/2A3 and it was out of sight . . . and stayed that way.

I have since added a comparison on Mini Tumble-Recovery Rockets - See Here.

GUEST's OPINION:
01/04 - "Decided to build this little guy on a lark, never figuring that I would find it after it's first flight. It shot off the pad like a bullet, and I lost sight of it right away. While watching downrange (7kt winds) on the odd chance I'd see it come down, I heard a a thunk behind be. There was the Quark, stuck in the ground like the proverbial lawn dart. less than 10 feet from the pad. I may wear a hard hat if I launch this one again." (J.H.E.)

GUEST's OPINION:
06/03 - "It even LOOKS like a lawn dart. Form follows function, I guess. You might as well glue the fins and the lug directly to an engine and get it over with. Like its sister "tumble recovery" rockets, the Quark leaves the pad at approximately .5 Mach, zipping into the sky on a thin exhaust trail, never to be seen again till you come to the park the next year to launch a new one and step on the old one..." (J.F.)

GUEST's OPINION:
06/03 - "This is the closest thing to a disposable rocket as I've seen...No mater what color it's painted it becomes invisible due to its speed at launch! I've never had a recovery and I launch from a large field...even with spotters. Sure it's a lot of fun and very easy to build, but I'd love to have some type of recovery system, such as a streamer. Next time I'll add one." (K.R.E.)

GUEST's OPINION:
09/02 - "This was my first rocket. It took me about an hour to build. I painted the fins and nose cone Salem green, and the body tube dark blue. BIG MISTAKE!!! If you get one, be sure to paint it bright colors. I launched it with an A-10. it went up so fast all I saw was the trail of engine powder. Me and my friend went looking for it, and it was buried nose cone deep, about 100 feet from launch pad." (unknown)

GUEST's OPINION:
01/02 - "I like this rocket because of it's accurate landing. once it landed 10-20 feet away from the launch pad! I think this rocket is in the top 3 for the most accurate. You should paint your Quark bright colors so it is easier to find. The Quark is one of the easiest rockets to make." (J.A.)

GUEST's OPINION:
08/01 - "This is a fun kit. I flew it on a 1/4A and it was out of site. And like others say it does not tumble, it embeds. I saw it lift off....silent..then THUNK and it landed next to me. Wear a helmet when launching :-)" (J.H.)

GUEST's OPINION:
07/01 - "Nice looking kit, built it in about 1 hour & painted it the following day, day-glow yellow on 2 fins & between them & bright red on the other 2 & painted half the cone black. I thought the bright colors would make it easier to track. Launched it on an A8 watched it leave the rod & up for about 100ft, heard the ejection charge, but it was never seen again! That was my first kit gone! It really did look good!" (D.B.)

GUEST's OPINION:
02/01 - "I built my Quark in August and have probably flown it 12 times since on A10-3s. On a couple of occasions I had the good fortune of keeping my eyes on it for the entire flight, and let me tell ya, it comes down as fast as it goes up. Considering the lawn dart like recovery I would guess that getting hit in the head with the pointy end off the Quark would feel like getting whacked with a golf ball. It's quite a thrill to hear the stereo "THUNK THUNK" of the Quark and it's engine landing on either side of you. Wear a hat!K.W." ()

GUEST's OPINION:
01/01 - "The Quark is really good. I painted mine teal. I used an A10-3 my first flight. It went straight up, until I lost sight of it... The package says it can go up to 700 feet, and I believe it. I never say it again. I would have gotten another, but the store was liquidating and were out. I hope to get another soon. Great rocket." (B.)

GUEST's OPINION:
10/00 - "I have recently built and flown a Quark. I painted my Quark's body and fins day-glow yellow and the nose cone red. My first flight was on a 1/4A3-3T. Conditions were calm and I never lost sight of the rocket. It landed about 7 feet from my launch pad. The flight back down was hard to watch because the rocket came in like a lawn dart and bore its entire nose cone into the ground. After brushing off the dirt from the nose cone, it was ready for its second launch. On the second flight I used an A10-3T. I lost sight of the rocket almost immediately after it left the launch pad. Looking around the launch area, I saw the rocket clearly from about 50 yards from my launch pad. Again the rocket did its impersonation of a lawn dart but was not damaged. I'm sure I would have lost this rocket if it weren't for the day-glow paint. I like this little rocket and am glad I recovered it." (M.B.)

GUEST's OPINION:
09/00 - "The Quark was fun to build and the decals are a nice touch. Hit the launch button, saw a flash of rocket against the sky and never saw it again in the air. After we packed up, we drove around looking just for the heck of it and miraculously spotted the white fins sticking up out of the short grass. The Quark had lawn darted under power into the soft turf. We laughed and decided it was a better rocket to display than fly." (F.D.)

GUEST's OPINION:
12/99 - "The previous reviews are right on the money. It doesn't tumble and will bury itself in soft ground. If it weren't for the white fins we may not have found it in the short grass. Flies high and straight." (M.P.)

GUEST's OPINION:
"My Quark has flown 5 times on AT-3T's. Painting it all white helps tracking this small kit. The review was accurate." (O.S.)

GUEST's OPINION:
"I've built 2 Quarks, had 2 successful recoveries, and 2 lost. It's very difficult to track. It does not tumble down, it flies straight down and may burrow into soft ground - or someone's head if your not careful. Be prepared to lose one or two." (J.S.)

[Enter Rocket Specific Tip]

SPECIFIC ROCKET TIP:
12/06 - "Short to no grass field is preferred. No wind. Launch in the morning or after noon as the sun is high otherwise. Paint this rocket with UV reactive paint on the fins and day-glo paint on the nosecone and body tube (even though the nosecone is going to be buried). You will be able to see it better in the light and if you don't find it in the daylight, get one of those blueish led flashlights and go out at night. It will glow when the light hits it. Be sure to keep the light near your feet as you may step on it in the dark. Portable blacklights work the best...you may also want to paint it with Krylon glow in the dark paint after you apply colors. It will have a glow for a while after the sun goes down." (J.E. )

SPECIFIC ROCKET TIP:
07/04 - "A good idea that will help you get your Quark back is putting streamers on the tips of all four fins. Make sure they are all the same length. The only down side to this is that the flights are lower. But hey its worth it if you can get your roc back." (M.R.H. )

07-15-2001 Robert Brown Est SU 1/2A3-4 Apogee - NC Down 0-5 mph winds Nose Dive - Nice boost to ejection. Loud pop (too loud) and another nose dive. Ejection charge blew seams in body.
07-15-2001 Robert Brown Est SU 1/2A3-4 Apogee - NC Down 0-5 mph winds - Dangerous rocket, flew 100+ altitide and nosed into ground twice. Too much mass in plastic nose.
07-18-2001 Robert Brown Est SU 1/4A3-2 Apogee - NC Up 0-5 mph winds Nose Dive - Added vents to body below top of motor to allow gases to discharge after motor started ejection. Reinforced with CA. Nose Dive.
07-21-2001 Robert Brown Est SU 1/2A3-4 Apogee - NC Up 0-5 mph winds Nose Dive - Added extended engine hook to stop motor's rearward movement at negative CG position. Ejection charge ripped it off. Nose Dive.

05-31-2004 Carl Cravens Est SU A3-4 Didn't See 5-10 mph winds RIP - Beautiful launch, the A3 left a long smoke trail. A moment later, I saw the puff of smoke from the ejection charge and never saw a trace after. The first rocket my son (4 yrs) and I built together. We'll build another. Status: Lost
06-15-2003 Nelson Eisel Est SU 1/2A3-4 Very Late Didn't Record DF00-Chibiquark - Mounted fins along body for fun... highly unstable! Spun end over end, lawn-darted into model airplane runway. Broke fin, fixed.
06-15-2003 Nelson Eisel Est SU A10-3 Just Past (1-2sec) Didn't Record DF00-Chibiquark - Still with the wrong fin configuration. Actually got ~40m up before starting to tumble. Engine ejected out, rocket landed in grass.
06-15-2003 Nelson Eisel Est SU A10-3 Very Late Didn't Record DF00-Chibiquark - Snapped 2 fins off & mounted them the right way... Launched, 30m up spun, tumbled down on coast, ejected 10m up pointed down towards spectator (missed)! Lesson learned: basics first, THEN experiment.
10-10-1998 David Fergus Est SU 1/2A3-4 Didn't See Calm - lucky to find this green and yellow thing in the grass down range.
07-08-2001 David Fergus Qst MMX Apogee - NC Down Calm - accelerated into ground at ejection
07-08-2001 David Fergus Qst MMX Apogee - NC Down Calm - tired to aim it across the street to land in neighbors lawn, but didn't quite make it and got a little torn up from the street

12-18-2004 Scott Hauff Est SU A10-3 Didn't See 5-10 mph winds RIP - Alas, my quark is gone!!! I am happy to have gotten at least 2 flights out of it though. Isn't there some way to recover this better???? Status: Lost
03-21-2004 Forrest Henry Est SU 1/2A3-2 Apogee - Perfect Calm RIP - Second flight of this Quark. Great straight flight, but went FOOSH-POP and never saw another sign of it (found the engine). Maybe dark green isn't a great color for the Quark... Status: Lost
05-08-2005 Chase Hrncir Est SU 1/4A3-3 Didn't See 10+ mph winds - Sportflyers Estates, Brookshire, TX--Great flight, landed 10 ft from me.
08-07-2010 Chris Jeppesen Est SU A10-3 Didn't See Light winds Davey - A woosh and it was gone. We saw the tracking smoke, but no sign of the rocket until it lawn-darted about 10 feet from one of us. Stuck about 1/2 inch in
08-07-2010 Chris Jeppesen Est SU A10-3 Didn't See Light winds Davey - Again, I didn't think it would ever come down, but apparently they scream down just like they scream up. Fins painted green/purple, body white, somewhat hard to find.
12-09-2007 Mark Lafavor Est SU 1/2A3-4 Didn't See 10+ mph winds - Great first flight, but very difficult to see. It landed about 10 feet away. The nosecone was buried about 1/2 an inch. Due to the wind we didn't hear it land!!! Next time we will be wearing safety glasses! Ha Ha.
04-14-2006 Mal McClenaghan Est SU A3-4 Just Before 5-10 mph winds RIP - This rocket is a good demonstration of what can be done with a small amount of thrust. The Quark still climbing when the ejection charge went off. I didn't really expect to see it again. Status: Lost

12-28-2002 MikeyR Est SU 1/4A3-3 Apogee - NC Up 0-5 mph winds Bought It - Nice flight. Stuck in ground like normal Quarks.
04-23-2004 Mike Mistele Est SU 1/2A3-2 Just Before 5-10 mph winds - First flight. Arced with the wind. Saw the ejection charge blow, but didn't see it descend. Found it about 100 yards from the pad -- it had hit the street, and snapped 2 fins off at the root (will be easy to repair).
03-11-2004 Jerry Nishihira Est SU 1/2A3-4 Just Past (1-2sec) 10+ mph winds Event: Kamehameha School demo launch.
- good flight but rocket is so small it disappeared until I heard the pop from ejection. Rocket was coming nose down (without motor) and lawn darted. No damage but so much for the tumble recovery.

08-11-2003 Jon Revelle Est SU A3-2 Didn't See 5-10 mph winds - Nice flight. Almost lost. Needs a brighter paint color.
11-18-2000 Chuck Rider Est SU A3-4 Apogee - NC Up 0-5 mph winds - Out of sight
01-20-2001 Chuck Rider Est SU A3-4 Didn't See 0-5 mph winds RIP - Out of sight - Lost the rocket Status: Lost
07-25-2002 John Rowan-Stern Est SU 1/4A3-2 Apogee - Perfect 5-10 mph winds RIP Runaway - This little rascal came off pad nice and straight with very little wiggle. When engine finished I saw the ejection, but even the bright orange paint didn't help. Found engine casing, rocket MIA!!! Status: Lost
07-27-2010 Tyler Runyon Est SU 1/2A3-4 Apogee - Perfect 5-10 mph winds Event: Driveway
- Straight up, lost after ejection. Found a day later while moving chairs in back yard before mowing. Good thing I saw it.

08-24-2003 Chan Stevens Est SU 1/4A3-3 Didn't See 10+ mph winds - I've actually flown this 5-6 times now
10-08-2006 Chan Stevens Est SU 1/4A3-3 None - Tumble 0-5 mph winds - Actually recovered it!
06-01-2007 Chan Stevens Est SU 1/4A3-3 Very Early 5-10 mph winds Event: NSL-2007
- Got it back, too!
09-22-2007 Chan Stevens Est SU 1/4A3-3 Didn't See 5-10 mph winds -
08-24-2003 Steve Thompson Est SU A10-3 Didn't Record Calm RIP - My girlfriend said it went to heaven where other big kids can enjoy the Quark like we did. I guess I won't sand and fill the fins next time. Status: Lost
08-07-2004 Andy Turits Est SU 1/2A3-4 Didn't See Calm - Duplicate of previous flight and recovery situation. Landed 180 degrees opposite of previous flight. Again no damage. Great big fun for a little inexpensive low maintenance guy
08-07-2004 Andy Turits Est SU 1/2A3-4 Didn't See Calm - Quick straight lift off beyond visual range to see ejection (500 ft?). Fins sighted straight up about 80 ft. from pad. 3/4 core sample. Nose took impact nicely without any damage to vehicle
03-08-2003 Matt Vennard Est SU A10-3 Apogee - NC Up 0-5 mph winds - They aren't kidding when they say these go out of sight. Didn't see it on the way down, but heard the stereo plops as the engine and rocket hit the ground. No damage. Fun little rocket.
03-08-2003 Matt Vennard Est SU A10-3 Apogee - NC Up 0-5 mph winds RIP - Second Flight. Just as high as the first. Recovered engine, but rocket wasn't found. Status: Lost
