REC'D MOTORS: 29mm, 24mm (with adapter); D12-3, E, F, G

(Contributed - by Steve Graham - 08/10/02)

Single stage, 14" parachute recovery at apogee using motor ejection.

Two airframe BT's (27", 13"), 1.6" LOC nose cone, 3-plywood fins, 2- paper centering rings, LOC-type 29mm motor mount tube (8"long), 1 coupler, bulkhead, and eye screw.

You also receive a length of 1/4" elastic for a shock cord. No decals.

Instructions are straight forward. I always expect good things from Barry. The construction was very simple, with tips on how to beef up your fin joints for higher power flights. No alignment problems. Everything went together very well. Because, I intend to fly mine on H and I motors, I beefed up the fin joints with fiberglass.

No special requirements are needed for the airframe and fins to get it ready to paint. However; with all LOC nose cones, be sure you take extra care in prepping it for paint. I usually sand mine down starting with about 150-grit and progressing up to 600-grit. It makes for a nice smooth finish that will stand up to a lot o abuse.

The only CON I found with this kit is that it doesn't come with decals. I didn't worry about it that much as I just purchased vinyl letters.

Construction Rating: 5 out of 5

On the day of the flight, I used an Aerotech G64. Since I replaced the shock cord with Kevlar and a chute protector, this made prepping recovery very easy. The rocket lifted off the pad straight and true. With the prevailing winds from the south at our launch site, the rocket ended up drifting down range a bit. Never the less, it was recovered in perfect condition.

Since the trailing edge of the fins are 1 caliber in front of the aft end, the chance of breaking a fin is minimized.

Next, I loaded it with an H128, which gave us a neck snapping launch. Again, the rocket performed flawlessly.

The third flight of the day was with a single use F32 with a 24mm motor adaptor. It wasn't as exciting as the H128. The F32 launched it to a respectible altitude. My shock cord got tangled in the shroud lines. So the rocket flat spinned into the Texas grass. I'm glad I glassed the fins now.

Shock Cord: replaced with Kevlarsc rollbars=no,menubar=no'); "> from Apogee Components.

Parachute: 14" flat panel- rip stop nylon. IMHO, too small. This rocket needs at least a 24" to recover it. I think a 14" was chosen because the fins are situated 1.5" ahead of the aft end of the rocket. Thus, reducing the chance of breaking a fin on landing.

Flight Rating: 4 out of 5

I don't have any bad things to say about this rocket. It went together very well and quickly. As I stated above, it needs a larger parachute. And replace the elastice shock cord with Kevlar.

(Contributed - by Lance Alligood [Who's Who Page] - 05/19/05) LOC/Precision Weasel

The LOC/Precision Weasel is a simple, near minimum diameter 3FNC MPR that can fly as little as an E or absolutely tear a hole in the time-space continuum on a high thrust H.

The Weasel is a basic kit with a minimal number of parts. The kit includes:

  • 1 1.63"d ogive plastic nose cone
  • 1 38mm x 11.5" payload tube
  • 1 38mm x 27" body tube (premarked for fins and launch lug)
  • 1 coupler
  • 1 birch plywood bulkhead
  • 1 screw eye
  • 3 birch plywood fins, 1/8" thick
  • 2 paper centering rings
  • 1 29mm x 6" motor mount tube
  • 1 14" nylon parachute
  • 6ft elastic shock cord
  • 1 shock cord mount
  • 1 launch lug, 1/4"ID
LOC/Precision Weasel

The build went very quickly and offered no surprises. I started by briefly reading the instructions, which I found to be a little on the thin side content wise, however, anyone who has built even a few LPRs shouldn't have any problems with the Weasel. The directions recommend using epoxy for the build, but I am confident that my usage and application of yellow wood glue (aliphatic resin) for the wood and paper components will also be more than adequate if not as durable in building this kit. The motor mount was simply 2 paper rings and a tube. To attach the fins, I rough sanded the body tube with 150 grit sandpaper (almost to the point of sanding the premarked lines off) and then used the "double glue" method for tacking the fins to the airframe. 2 applications of yellow glue fillets followed. The fins offered little if any flex after the fillets were applied.

I should mention that I did use a small amounts of polyurethane glue and epoxy in the build. The polyurethane glue is my preferred method of securing the screw eye into the coupler bulkhead as it foams slightly to create a satisfyingly sticky bond between metal and wood. The 12-minute epoxy with a little milled fiber for added strength and thickness was used to attach the nylon string shock cord mount inside the main airframe tube.

Lastly, I'm not big on launch lugs so I drilled and attached a pair of rail buttons right into each of the paper centering rings with CA and saved the paper lug for another project. And while drilling the holes for the rail buttons, I also put 1/16" vent holes in both the payload and booster tubes.

Even allowing for everything to dry or cure, the Weasel went together in only a couple of hours.

I don't think I am alone in wishing that LOC/Precision should include decals with their kits. They just make their rockets look so doggone good on their website that it's simply wrong they don't include any decals or information on how to make yours look like the picture.

Decals aside, I kept the finishing work simple like the rest of the rocket. The fins were sealed with Elmer's Fill 'n' Finish and then sanded smooth. The tubing has slightly noticeable spirals but I didn't feel that they were enough of an issue to warrant filling them. The rocket was then primed with Krylon white primer, sanded with 400 grit sandpaper, and then primed and sanded again. Finally I had myself an excellent opportunity to apply a color I'd been wanting to use for some time: Krylon Gloss Watermelon. It's not too soft a pink to be considered feminine (not that there's anything wrong with that) but it is such an eye catching color! I added Krylon gloss purple as an accent color--another great color that should be great for helping locate the rocket in the field! I painted a couple of fins and halfway around the body tube so I can easily track any rotation during flight. For a final touch, I added some automotive pinstriping.

Construction Rating: 5 out of 5

Prepping the Weasel for flight is reasonably easy. There isn't much room for any kind of external motor retention so masking tape is the obvious solution to holding the motor in place. A handful of dog barf cellulose wadding goes in the other end of the booster tube followed by the shock cord and chute before closing it up and putting it on the pad. An AeroTech G104T-M was used for the Weasel's first flight. While the total impulse is rather low, I liked this motor because of it's high average impulse! I used that motor with the intention that the rocket would zip off the pad but not go ridiculously high. Well, if nearly 2000ft is someone's idea of not ridiculously high!

The Weasel flew just as I expected it to. The high thrust, fast burning motor sent the Weasel up on a long, mostly silent glide to apogee where it ejected right on cue. Excellent!

The 14" chute is tiny but made of non-porous rip stop nylon with some stout shroud lines (almost certainly strong enough to serve dual duty as a drogue chute for larger rockets!) If the chute didn't come with the kit, I'd probably (and still might in the future) switch it out for a plastic streamer. The chute is small compared to the rocket's size and that might alarm some builders new to MPR. However, it should not only be more than adequate to safely get the rocket down, the rocket's aft end with the motor mount and the fins are placed far enough forward that the rocket would sustain extremely minimal damage if any at all on all but the hardest surfaces. (In fact, you can pretty much guarantee that it's the motor casing that will accept the brunt of landing impact regardless of launch site.)

I attached the chute with a quicklink so that I can attach it as needed to the shock cord. And speaking of the shock cord, it is 6 feet of standard 1/4" elastic--basically an upscaled version of what you'd find in a typical LPR kit. I didn't have any problems with the quality of the elastic but I thought it to be a little on the short side, preferring an extra 2 or 3 feet. I used it anyway and it proved to be an acceptable length. The nylon string that is epoxied just inside the forward end of the booster appears to be pretty rugged and makes the elastic easy to replace if necessary in the future.

The chute came out perfectly and the rocket descended quickly. Being a relatively light rocket, I didn't want it drifting anyway. The chute and shock cord are more than acceptable for this rocket.

Flight Rating: 5 out of 5

The LOC/Precision Weasel is a great introductory MPR kit for someone making the transition from LPR. It uses many similar build techniques found in LPR and is a simple design that shouldn't overwhelm the builder. The small diameter of the kit means that you're most likely going to have to resort to masking tape friction fit motor retention but that is a technique worth learning. About the only other thing someone might need for this kit is a 29-24mm motor adapter to fly it on 24mm E and F motors.

06/05 - "This is one bulletproof rocket. I've had some trouble with recovery on two flights, an Ellis Mtn. G35 and an Aerotech G35. In both cases, the 'chute and shock cord tangled badly. On the last flight, the cord snapped in two at the chute attachment point. Payload and booster sections came down free-fall from about 2800', and the only damage was some scratched paint. I have no doubt it could take the Ellis long-burn 29mm I69 and probably tickle 10,000'." (P.C.)

08/02 - "Since the writing of this review, I have built another Weasel. This time, I built it with minimum diameter 38mm motor mount. I glassed all tubes and fins. There is an altimeter bay in the coupler that houses a Missile Works RRC2. The altimeter bay has bulkheads machined out of T-6 aluminum. (very light compared to wood, but stronger). In the picture, you will notice a chrome tape placed around the aft section behind the fins. My modified version has a machined aluminum collar replacing that tape. (Machined myself) It's machined to go up to just behind the fins. The aft part of the collar has a 3/4" section that is machined to match the ID of the airframe. Is used as a positive platform to support the thrust of the motor as well as motor retention. Plans are in order at the next launch to fly the new Weasel on a J350. RockSim indicates 8900 ft." (S.G.)

08/02 - "Nice review! I do think though, that the fiberglass was overkill. Given the materials, wood glue would be stronger and lighter. To smooth the fillets, try Fill'n'Finish sanded smooth, then soak with thin CA. Very light and strong." (R.T.P.)

[Enter Rocket Specific Tip]

09/04 - "The space between the main body and the engine tube is perfect for pouring in epoxy and embedded two screws/bolts into the epoxy head first for positive retention. When set, simply add washers and nuts. For 24mm motors, use wider nuts. If you want to do this and have already filled the gap with epoxy, simply drill out between the tubes in two places 180 degrees apart and do as stated. Even that small hole will retain the screw, as long as the entire head is embedded in epoxy. " (D.M. )

07/04 - "Fin attachment suggestion: Extend the fin markings up the tube about 8 inches. Line up one edge of a fin along the mark and draw the outline of the fin on the tube. Using a razor knife, inlet half way through the paper tube, one layer of paper at a time, inside the outline marks. Drizzle a small amount of 30 minute epoxy into the trench, and set the fin. A small amount of CA on the front and rear of the fin root will 'set' the fin in place in seconds. Let it set an hour, rotate the rocket and repeat. Trim back the glassine layer about 1/4 inch from the fin root to expose the underlying paper. Once you have all three fins set, use 30 or 90 minute epoxy on the fillets. The epoxy will have bonded into the paper and to the root of the fin. I use a 9 inch 'chute and let it come in fast. My Weasel has flown on F25-6 (1250') to G80-10 (3350'). F50-9 produces a fabulous flight. This rocket has survived a Cato of an F50-9 on the pad and continues to fly." (M.M. )

01/04 - "I was really bummed that the silver mylar tape on the tail of the Weasel was just decoration. This kit really needs something on the tail as an accent. I have added a boat tail on the kit that I am building right now to give this cool kit an even sleeker look!" (T.M. )

09/02 - "Weasel-29 fin attachment, Sanding through the glassine layer on the body tube is a must when attaching the fins on this rocket. Using a high quality epoxy such as West System, brush the epoxy onto the fin and body tube, fins may be tacked into place with CA. When the epoxy becomes tacky, mix some filleting material such as West System 404. Apply the epoxy mix with a popsicle stick, then shape the fillet with a spoon, this makes a perfect fillet! When the fins are attached this way, you'll never have a fin come off.(Regardless of the motor you fly)! My Weasel has seen some 20+ flights and has yet to lose a fin or even crack a fillet." (D.D.U. )

Wind Notes
05-21-2005 Lance Alligood AT RMS G104-M Apogee - NC Down 0-5 mph winds - Great rocket-motor combination. Quick boost with an enjoyably long coast to apogee. Rocket recovered quickly but a couple hundred yeard from the pad.
07-16-2005 Lance Alligood AT RMS G104-M Apogee - Perfect 0-5 mph winds - Even after flying this rocket with this same motor, I was blown away with the generous amount of altitude. High winds caused it to drift...right into one of the 2 canals around the field :( Thankfully it landed close enough to retrieve it.
07-18-2009 Lance Alligood AT RMS G71-10 Apogee - Perfect 0-5 mph winds TFD - Fantastic flight that left the pad with no hesitation. Excellent altitude. Recovered close.
07-18-2009 Lance Alligood AT RMS G71-10 Apogee - Perfect 0-5 mph winds TFD - Very similar to first flight but must've been a hard ejection as a fin got busted loose & it ejected my beeper's battery.
02-20-2010 Lance Alligood AT RMS G76-7 Apogee - NC Up 0-5 mph winds TFD - Excellent flight. Recovered close due to calm weather. Wished I'd had my PicoAlt on board.
04-17-2010 Lance Alligood Ces RLD G118-14 Didn't See 0-5 mph winds TFD - Fast burn G125. Left the pad in a hurry. Serious altitude. Recovered close.
05-15-2010 Lance Alligood Ces RLD G118-12 Didn't See
(2997 ft)
10+ mph winds TFD - Winds made this flight lower than it could have been. PicoAlt on board. Recovered a ways downrange.
05-15-2010 Lance Alligood Ces RLD H153-14 Didn't See 10+ mph winds TFD - Winds were calmed than previous flight, but still a walk to recover. Battery for PicoAlt malfunctioned so no altitude recorded.
06-19-2010 Lance Alligood Ces RLD G54-12 Apogee - NC Up 0-5 mph winds TFD - Ideal weather for this rocket/motor combination. SERIOUS altitude & it was a textbook flight. Unfortunately, my altimeter wasn't up for the job & malfunctioned.
10-16-2010 Lance Alligood Ces RLD G54-12 Apogee - NC Down
(2978 ft)
5-10 mph winds TFD - Ripped off the pad again. The high winds probably took some altitude off the flight, but it was still very pretty. Another rocketeer found it in a tree & cut it down.
06-17-2006 Lance Alligood AT RMS G104-M Apogee - Perfect 10+ mph winds RIP - Firstflight using my BRB BeeLine locator. Quick boost followed by a loooong coast to apogee. It drifted under chute into the nearby canal, however, the payload bay was watertight & kept the BeeLine safe & dry! I think I'll retire the rocket though. Status: Retired
07-18-2004 Andrew Barnhart AT EconoJet F20-7 Didn't See 0-5 mph winds - Good flight. Went straight up, landed quite close to pad.
08-21-2005 John Bowles Est SU D12-3 Just Past (1-2sec) 0-5 mph winds - Very low flight, late ejection. In this case 'Just Past' is 'halfway to the ground.' I wouldn't recommend this motor.

(1172 ft)
Calm Event: LDRS-28
Star Spangled Eagle - Our personal project for LDRS-28, colored red and blue with white stars. Lovely flight with this motor, but had a noticeable arc due to short rod.
08-11-2009 Charles Dennison AT RMS E18-4 Apogee - Perfect 5-10 mph winds - Second flight, first time use of an RMS motor. Another good small field rocket and motor combo. Rocket recovered 75ft. from pad.
08-10-2009 Chip Dennison AT SU E15-4 Apogee - Perfect 5-10 mph winds - First flight for the Weasel, great motor for a small field. Rocket recovered 50ft. from pad in perfect condition.
08-13-2009 Chip Dennison AT RMS E18-4 Late (2-3sec) 0-5 mph winds - Third flight second time using the 24mm RMS. I thought this would be the last flight as the rocket turned nose down anb started to gain speed, pop out came the chute anb a safe landing. The rocket landed 50ft. from the pad.
09-26-2004 Rocky Firth AT RMS H180-L Didn't See Calm - Lost track of it, liftoff was so fast that even the tracking smoke wasn't a lot of help. Lost the nose cone but the rest of the rocket was recovered just 150 yards from the pad after making a lazy swirl around the site.
08-02-2002 Steve Graham AT RMS G64-7 Apogee - Perfect 5-10 mph winds - Used a shorter comparable delay for this flight. The chute deployed at apogee. Although it landed farther downrange, no damage.
08-02-2002 Steve Graham AT RMS H128-15 Just Past (1-2sec) 5-10 mph winds - This was the first flight. The chute popped a little after apogee due to the long delay. The rocket was recovered with no damage.
08-02-2002 Steve Graham AT SU F32-10 Just Past (1-2sec) 5-10 mph winds - Good flight. Rocket attained apogee and started to nose down. The chute popped and floated down without any damage.
08-02-2002 Steve Graham AT SU F32-10 Just Past (1-2sec) 5-10 mph winds - The chute popped a little after apogee due to the long delay. The rocket was recovered with no damage.
07-09-2005 Jeff Hartman AT RMS F40-7 Apogee - Perfect 10+ mph winds - Great flight, straight and true. Plenty of thrust from this RMS motor. Rocket drighted far away due to high winds but was recovered.
07-01-2006 Zachary Jones AT RMS F40-7 Apogee - Perfect 0-5 mph winds Event: Mc2 launch
- straight boost, parachute fully deployed. Landed close to the pad. rocksim predicted around 2000 feet.

04-03-2010 Peter Lam AT SU G80-10 Apogee - Perfect 5-10 mph winds Event: Serpentine Launch
- Shot off the pad, nosecone came off on ejection (later found) needs vent hole on payload section but a good flight and recovery
01-19-2009 Mike Lysic AT RMS E16-4 Late (2-3sec) 0-5 mph winds Event: MIS
- Good Motor for a smaller field, great flight, straight and stable. Ejection was VERY late(the notorious AT 4 second delay), but finally happened relieving my anxiety that was quickly setting in.
03-14-2009 Mike Lysic AT EconoJet F20-4 Just Before 0-5 mph winds Event: Gumbert's field
- Great flight, it really moves out on the F20, the 7 second delay would be better though. The Weasel is a real Hot Rod, it really moves out.
05-22-2010 Mike Lysic AT EconoJet F20-7 Just Past (1-2sec) 0-5 mph winds - Holy Cow!!! That was the longest burning F20 I've ever seen, seriously, none of us present there could believe the long burn. Very high flight. Almost lost to the woods, but I got very lucky, we saw the chute pass thru the trees and land on the ground.
09-08-2004 Dennis McClain-Furmanski AT EconoJet F21-4 Just Before 0-5 mph winds Event: METRA 9/4/04

12-13-2009 Leigh Metzroth AT RMS G77-10 Apogee - Perfect Calm - Shock cord snapped about 6 from the sustainer. Nose and chute landed about 400ft away and the sustainer backslid/glided to about 600ft away. Luckily some other members watched it came down and found it for me!
01-10-2010 Leigh Metzroth AT RMS G64-10 Apogee - Perfect Calm - Got a little rod whip off the pad so it went a bit south and after a 45 minute search I finally found it about 30m into the corn field!
02-14-2010 Leigh Metzroth AT RMS G53-7 Apogee - Perfect 5-10 mph winds RIP - Landed in the 8 foot tall corn field due to wind drift. And it has rained since the launch... Status: Lost
06-03-2006 Todd Mullin AT RMS F40-7 Very Early 0-5 mph winds - No vent hole in main airframe caused seperation in boost. No damage to rocket, just my ego...
