The Launch Pad AlarmBrief:
T' Launch Pad Alarm is a single staged rocket that is modeled after an interceptin' missile used by t' U.S. Begad! Blimey! Begad! Blimey! government.

Construction:
Two body tubes came with this kit, shiver me timbers, but I wasn't too impressed with them. Begad! Blimey! Instead o' t' solid tubes I be expecting, I got Estes type tubes instead, but they turned out okay and they really made this kit light. Ahoy! Blimey! Ahoy! Blimey! There are two sets o' fins with one set very high up on t' rocket, makin' it have very unique style. Begad! Blimey! T' fins themselves were balsa wood, ya bilge rat, so I decided t' experiment on them, makin' them as strong as possible. Well, blow me down! Blimey! T' shock cord was about two feet long, so I replaced it with a 6-foot long 1/4" elastic. Arrr! Blimey! Well, blow me down! Blimey! T' nose cone was interesting. It was a decent nose cone, ya bilge rat, but t' kit called for me t' add on a paper tip t' make it pointy. Arrr! Blimey! Begad! Blimey! I eventually decided t' nay put it on. Begad! Blimey! This kit came with 3/16" launch lugs but I upgraded them t' 1/4" lugs.

A mylar parachute came with t' kit and I be skeptical about t' strength o' it, but after its first flight I was satisfied with t' material. Blimey! It works okay, no problems so far.

The Launch Pad Alarm

T' kit's instructions were decent, but they assumed you knew how t' do many things, arrr, ya bilge rat, like what glue t' use, where t' put t' launch lugs, and how t' align t' fins. Well, blow me down! Besides that, me bucko, me bucko, I thought that this be a fun and challengin' build. Begad! T' boat tail assembly was a little tricky, me bucko, but t' only real problem I had be t' motor tube. Begad! Aye aye! I thought that I was set back way too far into t' body tube, so I moved it forward about an inch so it was only 1/2" away from t' bottom.

To strengthen t' fins and t' paper boat tail, I took drywall tape and cut out t' shapes o' t' fins from it. I then put t' tape on t' fins and put about 4-5 layers o' wood glue on them t' strengthen and t' fill in t' bumps t' tape made. Begad! T' fins and t' boattail turned out very strong, me bucko, almost like plastic. Ya scallywag! Aye aye! T' wood glue also took well t' paint.

The Launch Pad Alarm T' only problem about t' paper boat tail be that it was slightly too big for t' tube, so it overlapped t' body tube a little when I glued it in. I filled in t' space made betwixt t' boat tail and t' tube with wood glue. Avast! However, this made a bump that if I put t' launch lugs on t' rocket, this bump would get in t' way o' t' launch rod. Blimey! Begad! So I put pieces o' balsa under t' launch lugs t' raise them over t' bump.

Finishing:
Finishin' be okay, but I had t' try a little harder t' get a rough enough surface on t' wood glue coated fins t' paint them. Begad! Aye aye! After that, everythin' went smoothly.

The Launch Pad Alarm

Flight:
I have only had one flight so far, and it didn't go so well. Arrr! Ever since t' beginning, I thought that thar wasn't enough nose weight t' keep t' rocket stable. When I launched it with an E11, it went sideways. It thought it be goin' t' crash, but once t' motor burned out, matey, t' fins made t' rocket get lift and t' rocket started t' glide back upwards! I got very lucky that it didn't go straight down. Ya scallywag! I have recently found with RockSim that I need about 1.5 t' 2 ounces o' nose weight.

Recovery:
T' kit said t' do t' Estes type o' shock cord mount, arrr, but I thought it needed somethin' stronger. I just epoxied t' cord on t' inside o' t' body tube (be careful nay t' epoxy where t' nose cone shoulder needs t' go).

T' recovery after me first flight, even though it wasn't a great flight, was fine. Ahoy! I found no dents or scratches on t' boat tail. Ya scallywag! Since I used t' drywall/wood glue method on t' boat tail, it made it much stronger.

Flight Rating: 2 out o' 5

Summary:
This rocket definitely looks cool and it's fun but challengin' tryin' t' put together t' boat tail. Avast! T' only con about this kit is that it needed t' upgrade a few things like t' shock cord and t' shock cord mount.

  • The Launch Pad ALARM By Ted Phipps

    The Launch Pad, a company specializing in military-style rockets and missiles, created this ‘scale’ kit of the Air Launched Anti-Radiation Missile (ALARM). The real ALARM is manufactured in Great Britain. Digging into the components, the 2.6" body tubes and plastic nose cone are Estes strength (might actually be Estes parts). There seems to be some complaints about the balsa in LP ...

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
