Brief:
T' Launch Pad make a wide range o' scale mid-power model kits o' missiles. They usually fly on one or more 24mm motors. Avast, me proud beauty! They fly best on AP motors in the E - F range, but can usually be flown with moderate success on BP D power. Ya scallywag! I was attracted t' this kit because it's a cool lookin' British prototype, ya bilge rat, and relatively cheap. Blimey! T' skill level is '4', but thar be no indication as t' what this means.

T' kit contains t' followin' parts:

  • 24mm motor mount
  • Motor clip
  • 3 centerin' discs
  • Plastic nose cone
  • Nose weight
  • 2 2.6" body tubes
  • 2 couplers
  • 2 3/32" balsa sheets
  • 8 1/4" x 1/8" balsa strips
  • 8 cocktail sticks
  • Paper fin templates
  • Paper aerial covers
  • Paper nose cone extension
  • Paper shock cord mount
  • 18" octagonal mylar chute
  • 8 Shroud line anchors
  • Shroud lines
  • Slip swivel
  • Barrel swivel

Construction/Finishin' Techiniques:
What you get is fairly similar t' a large Estes kit. Begad! Ya scallywag! It compares well with the Estes Phoenix, ya bilge rat, though if you decide t' use t' nose cone extension, t' Rapier requires more attention t' finishing. Begad! T' quality o' instructions is perhaps not quite as good as a similar sized Estes kit, shiver me timbers, me hearties, but are still adequate. There are no decals, but additions such as t' swivels make up for this.

T' motor mount and is very similar t' an Estes mount, matey, ya bilge rat, and goes together very easily. Begad! Aye aye! Two o' t' centerin' rings are glued over t' motor mount. Ya scallywag! I used yellow wood glue throughout construction. Begad! Ya scallywag! This makes for joints stronger than the cardboard and balsa and I find it easier t' use than white PVA.

T' paper nose cone extensions which feature in many o' Launch Pad kits are infamous and have started many a thread on rec.models.rockets. Begad! Avast, me proud beauty! Some say they are easy t' put together, ya bilge rat, others despise them. Well, blow me down! Arrr! Personally, ya bilge rat, I'm nay much bothered. Blimey! T' kit will still produce a flyable model with or without the extension. Although I did try t' make t' extension followin' t' instructions carefully, I failed miserably. I replicated t' template and tried again with no more success. Avast, me proud beauty! Ya scallywag! T' problem for me is t' make a sharp tip. Avast! It's just too hard to form it without creasin' t' paper. Avast! I didn't give up though. Well, blow me down! I tried again usin' an alternative technique. Ahoy! Instead o' usin' just t' amount o' paper needed t' form t' cone, I started with a much bigger sheet o' paper. Blimey! Begad! I found that this could be formed into a large cone, arrr, matey, t' tip o' which matched t' cone required. Ya scallywag! This could be done without ever touchin' t' tip, arrr, meanin' thar be a good sharp tip, and no creases. Ya scallywag! I applied glue after formin' and held it until it set. Aye aye! Once t' glue had dried I cut t' tip from t' large cone. It took me a couple o' attempts t' get t' angle right, but this was because on t' first attempt I neglected t' measure it! T' finished cone be glued t' t' plastic nose. T' instructions say t' coat t' paper extension with CA, but I decided I was goin' t' coat t' entire model in finishin' epoxy, arrr, so I omitted this step. Instead I gave it a couple o' coats o' sandin' sealer t' add little strength and t' stop it soakin' in too much epoxy.

T' body tubes are good quality. T' two lengths are connected together with the coupler. Avast! Blimey! T' motor mount is glued approximately 2" inside t' lower of the two body tubes. T' remainin' coupler is used t' position t' motor mount, and also t' strengthen t' end o' t' body tube. Ahoy! T' third centerin' rin' is glued 6" inside t' top o' t' body such that it prevents t' chute from slippin' backwards at launch.

T' fins must be cut from t' balsa sheet provided. There are no markings on t' balsa sheet, arrr, and templates for both sets o' fins are provided. Begad! It would be easy for the novice t' run-out o' balsa due t' bad lay out. Two slots must be made in the four forward fins t' mount t' aerials. Blimey! Begad! T' aerials are simply made by trimmin' t' cocktail sticks t' length. T' balsa strips are for t' fin mounts. Avast! These must be cut t' length, me bucko, and then 3/32" slots cut out t' mount the fins. Ahoy! This isn't easy as t' parallel cuts required are very close together. Ya scallywag! Avast, arrr, me proud beauty! A good metal straight edge t' control t' knife is a must. I gave the fins two coats o' sandin' sealer with a light sand betwixt coats.

To finish t' rocket I tried a new (for me) technique. Arrr! Aye aye! I painted t' entire surface with finishin' epoxy (zpoxy brand). This is a little different to normal epoxy in that it's much runnier, and almost completely odorless. Well, blow me down! It went on OK, apart from a couple o' areas that seemed t' suffer from t' 'surface tension' effect you see when you dab water on a water proof surface. I've since discovered that this can be prevented by lightly sandin' t' areas before application. Avast! Once dry a light sand overall was all that was required before the primer could be applied. Ahoy! A single coat o' primer and a single final coat were all that were required. Ya scallywag! T' instructions are pretty vague when it comes to paint schemes, matey, with just a single illustration and no decals. I searched the web and found schemes for t' British Army (olive) and Saudi Army (sand), me hearties, but instead went with overall orange that seemed t' be indicated by t' package illustration.

    ( Contributed - by David Urbanek - 07/16/99) Introduction: This is a scale model of a British surface to air missile. The kit is on the line of an Estes kit for balsa quality and body tube wall thickness. In other words, it's a lightweight rocket, that looks huge. The idea behind this is you can launch this rocket many times for the price of one really high power launch. However, the ...

The Rapier was the first ?big? rocket that I built when I became a BAR. I flew it at least six times, most of the flights where wonderful. It needs an E motor to fly well though. Unfortunately, I crashed it ? my fault I think. I was so heart broken that I decided to buy another kit. I used all the patterns to build a MUCH heavier version of the rocket using 1/4 in thick balsa fins, Aerotech tubes and nose. The rocket is much longer but flies great on an E-30. My wife painted it a cool camo design. I think I am going to build the actual LP kit again though. Thank you Launch Pad.
