[Alarm Pic]T' Launch Pad, arrr, a company specializin' in military-style rockets and missiles, created this ‘scale’ kit o' t' Air Launched Anti-Radiation Missile (ALARM). Begad! T' real ALARM is manufactured in Great Britain.

Diggin' into t' components, t' 2.6" body tubes and plastic nose cone are Estes strength (might actually be Estes parts). Aye aye! There seems t' be some complaints about t' balsa in LP kits, ya bilge rat, and this one be no exception. T' included balsa was softer than I’d select for me personal use. A couple o' impressions on t' rest o' t' parts; t' 18" copper-colored mylar chute is pretty cool, t' provided shock cord (1/4" elastic) is too short, and thar are no decals for this kit. Avast! Well, matey, blow me down! All o' it is pretty standard Estes type stuff.

T' instructions are very good, but basic. Aye aye! Listed as a level 3 kit, me bucko, many things are assumed, me bucko, such as puttin' t' launch lug in t' right place and knowin' what a cruciform is when layin' out t' fins. What this means is that you are free t' use your own techniques as you go. Avast, me proud beauty! Begad! You do get fin and transition templates.

When lookin' at t' fin template, we thought we’d discovered a problem. LP marks t' root edge o' t' fin on t' template, and I thought it was a ‘grain direction’ mark. This would’ve made for extremely weak fins, but t' instructions do specifically state "grain parallel t' t' leadin' edge". Begad! Ya scallywag! T' problem was me misinterpretin' t' mark on t' template.

After cuttin' out t' fins, ya bilge rat, you soak them in thin CA for strength, matey, and t' finished product is tougher than I expected.

T' ALARM features a boat tail and a cone over t' tip o' t' nose cone (to change t' profile). Avast, me proud beauty! Blimey! Both use heavy paper painted with CA t' strengthen them. Don’t rush things here, shiver me timbers, be prepared for several rounds o' filler and sanding, and t' results will be much better. Begad! Blimey! I also made some practice templates on a copier, me hearties, t' get a feel for how t' curves would form.

T' 24mm motor mount is recessed into t' boat tail a bit, me hearties, so we painted t' inside o' t' boat tail with CA for durability. Blimey! Motor retention is by a supplied motor hook.

You’ll need t' make your own fin alignment wrap (I used VCP). With eight fins (two sets o' four) alignment gets tricky, me hearties, but gettin' them straight up and down is probably more important than bein' perfectly in-line. Arrr! I replaced t' supplied shock cord with a piece about 3 times t' body length. I also cut t' supplied 3/8" launch lug in half and glued a piece into t' root fin o' each set – upper and lower.

Finishin' is simple. Begad! Ahoy! Fill, prime, sand and paint. T' ALARM is red with a few ½" black stripes. Blimey! Begad! We were goin' t' use pinstripin' tape from t' local auto-parts store, but I couldn’t find any wide enough. Ahoy! What I eventually did was print t' stripes onto blank decal paper and apply them like any regular decals. Avast! Blimey! T' final touch be a few light mistings o' clear-coat t' protect t' decals.

T' finished rocket looks very good, and seems t' be stronger than I thought it would be.

T' recommended motors are D12-3, me hearties, E15-4, ya bilge rat, E30-7 (all single use 24mm), and t' F25-7 RMS. Well, blow me down! Ahoy! For it’s first flight, we used an E15-4. T' boost was a little squirrely, me hearties, leavin' a smoke trail that looked like a sidewinder trackin' a movin' plane. Well, blow me down! Avast, shiver me timbers, me proud beauty! It straightened out nicely and t' chute ejected fine. Aye aye! There was no damage upon recovery. Begad! Avast! I’m goin' t' add some nose weight t' try and straighten out that boost, this might also mean I’ll have t' increase t' chute size.

Construction: 3 out o' 5 - Careful construction rewards t' builder.
Flight/Recovery: 4 out o' 5 - This is an excitin' rocket that delivers.
Overall: 4 out o' 5 - I like t' buildin' aspect o' rocketry, me hearties, me bucko, matey, so this be a satisfyin' project.

Don’t rush construction, matey, and your kit will look and fly great. Aye aye! Blimey! Avast, me proud beauty! Blimey! It’s big (44"), me hearties, and t' smallest motor suggested here be t' D12-3, so I recommend buildin' light.

* SPECIAL NOTE off o' RMR from Chuck Barndt, arrr, matey, shiver me timbers, President o' T' Launch Pad

  • The Launch Pad ALARM By Sean Walker

    The Launch Pad Alarm is a single staged rocket that is modeled after an intercepting missile used by the U.S. government. Two body tubes came with this kit, but I wasn't too impressed with them. Instead of the solid tubes I was expecting, I got Estes type tubes instead, but they turned out okay and they really made this kit light. There are two sets of fins with one set very high up on the ...

He is right about the fin templates! Be very, very careful. The lines on the templates are not the grain markings but where the leading edge is! This is directly opposite every other template I have seen, including other TLP kits!! I assumed the norm and cut the fins out the wrong way! Yuk! I didn't have any fin stock left so I tried to use a lot of CA to strengthen the wood but the finished rocket's fins are very fragile. I am almost afraid to fly it but I will (with a D12-3) and we'll see if the fins stand up. This rocket also has the paper nose cone cap which because it is pointed and not round at the top is extremely hard to shape properly. Good luck with it. Lastly, if you read my AMRAAM review, this rocket has the same problem, the engine is recessed a lot and the inside of the rocket body may get flame damaged. Being winter here, I haven't flown this rocket yet.

The 24mm motor mount appeared to be a standard Estes body type tube. I was not comfortable with this since I have had this same tubing distort even under a normal "D" engine burn. I replaced this tube with a Loc quality tube instead knowing that I would primarily be using Aerotech "E" engines. I too practiced my shroud making abilities and recommend this as well. The nose cone extension can be particularly tricky. I never could get my overall cone to look seamless even after building up the seam. Even so with the dark red color it is not too noticeable. Extending the shock cord is also recommended as the length supplied is about what you get in an Estes kit. The chute I got was metallic blue mylar which suffered burns on my maiden flight. I was concerned about the size (18") but feel it is ok for most landings. I did replace mine (since the mylar one burned) with a black 18" nylon chute that I had which looks good with the color scheme of this rocket. I was pleased with the quality of the balsa and found that the CA tip was helpful. I have been incorporating this technique into my other models. The rocket on a D12-3, its first flight, was somewhat unstable. After leaving the launch rod, the rocket proceeded to do the "Sidewinder" imitation and went sideways, fortunately away from the crowd. The 3 second delay saved the rocket from a nasty landing. I tend to build on the heavy side (epoxy and 5-6 coats of Krylon) and I am sure this contributed to the instability. The second flight at our local South Louisiana Rocketry (SOLAR) launch was picture perfect! I added appropriate nose weight and launched this time on an Aerotech E-184 reload. The rocket left the pad in that great white lightning roar. Wow! This was too cool. Definitely the engine to use for this bird. Overall, I am real pleased with this rocket. You may want to upgrade a few of the components (motor tube and shock cord). If you take your time you will end up with a beautiful and durable replica of the real thing that is a lot of fun to fly and is a real crowd pleaser. This is my first Launch Pad offering but will not be my last. I like the modeling challenge that these kits bring to the hobby.

I also have built one of these and I have to say that this is a nice kit. One thing though, although the manufacturer says it is an ALARM missile, it is definitely NOT! An ALARM (Air Launched Anti Radar Missile) does not have a pointed nose, and does have pointed wings. This missile is really a RAPIER. A british made surface to air missile. It is about a 95% match from a picture I have from defense web sites. Both the nosecone and wings match are a match to the rapier. So I painted mine military green and put the two yellow strips around the nose like I found in some pictures. Just look up Rapier , SAM on the web and you will find some good pictures. Have Fun, Ski

GS states that the TLP ALARM kit is actually a Rapier. 1: TLP makes a Rapier kit. The diferences are obvious. a: Rapier is a Surface-to-Air missile. ALARM is Air-to Ground. b: The fin shapes for the ALARM and Rapier are similar but substantially different. c: The forward fins for the Rapier have the trailing interferometer antennae. d: The nose cone for the Rapier is longer and more pointed than that of the ALARM. 2: TLPs ALARM kit is based on the prototype ALARM missile, and is advertised as such both on the website and on the color insert in every kit bag. ALARM was changed drastically before it entered production. The production missile has a shorter, blunter nose, a large sensor blister near the front of the airframe and the fins are slightly different. 3: Pictures of both missiles are available for comparison purposes on the TLP website: the-launch-pad.com. 4: One of several references which show the prototype ALARM is page 66-67 of "An Illustrated Guide to Modern Airborne Missiles" by Bill Gunston - 1983 Salamander Books, Ltd. London, UK. through ARCO Publishing. Although I am sure the Rapier paint job GS used on the ALARM is attractive, it would be most unusual to see such colors on an air launched missile. (Barring, perhaps, HELLFIRE).

I love this kit, I built the kit using just wood glue and a very little epoxy. I left the tail cone off, put in light plywood center rings and moved the motor mount down to the bottom of the airframe. I replaced the chute with a 24" nylon with spill hole and replaced the shock cord with Kevlar® using a small screw in eye on the top CR. No nose weight and no pointy paper tip. It flys on a D12 for low and slow flights and with an F21 it screams off the pad for nice high smoke trails. TLPAlarm.jpg
