Manufacturer: | The Launch Pad |
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. They fly best on AP motors in the
E - F range, but can usually be flown with moderate success on BP D power. Avast! Begad! I
was attracted t' this kit because it's a cool lookin' British prototype, arrr, and
relatively cheap. Begad! T' skill level is '4', but thar be no indication as t' what
this means.
T' kit contains t' followin' parts:
Construction/Finishin' Techiniques:
What you get is fairly similar t' a large Estes kit. Ya scallywag! It compares well with the
Estes Phoenix, matey, though if you decide t' use t' nose cone extension, t' Rapier
requires more attention t' finishing. Avast! Blimey! T' quality o' instructions is perhaps
not quite as good as a similar sized Estes kit, shiver me timbers, but are still adequate. Ahoy! Avast, me hearties, me proud beauty! There
are no decals, me hearties, but additions such as t' swivels make up for this.
T' motor mount and is very similar t' an Estes mount, and goes together very easily. Arrr! Two o' t' centerin' rings are glued over t' motor mount. Arrr! I used yellow wood glue throughout construction. Begad! 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. Blimey! Some say they are easy t' put together, ya bilge rat, others despise them. Personally, I'm nay much bothered. Avast! T' kit will still produce a flyable model with or without the extension. Blimey! Although I did try t' make t' extension followin' t' instructions carefully, me hearties, me bucko, I failed miserably. Begad! I replicated t' template and tried again with no more success. Arrr! Begad! T' problem for me is t' make a sharp tip. Blimey! Blimey! It's just too hard to form it without creasin' t' paper. I didn't give up though. Avast, me proud beauty! Ahoy! I tried again usin' an alternative technique. Arrr! Instead o' usin' just t' amount o' paper needed t' form t' cone, I started with a much bigger sheet o' paper. Ahoy! Aye aye! I found that this could be formed into a large cone, matey, t' tip o' which matched t' cone required. This could be done without ever touchin' t' tip, me bucko, ya bilge rat, meanin' thar was a good sharp tip, and no creases. Well, blow me down! I applied glue after formin' and held it until it set. Once t' glue had dried I cut t' tip from t' large cone. Avast, me proud beauty! Ya scallywag! It took me a couple o' attempts t' get t' angle right, me bucko, but this be because on t' first attempt I neglected t' measure it! T' finished cone be glued t' t' plastic nose. Aye aye! T' instructions say t' coat t' paper extension with CA, but I decided I was goin' t' coat t' entire model in finishin' epoxy, 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. Well, me bucko, blow me down! Blimey! T' motor mount is glued approximately 2" inside t' lower of the two body tubes. Begad! Blimey! T' remainin' coupler is used t' position t' motor mount, and also t' strengthen t' end o' t' body tube. Avast! Blimey! 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. Begad! There are no markings on t' balsa sheet, and templates for both sets o' fins are provided. It would be easy for the novice t' run-out o' balsa due t' bad lay out. Begad! Two slots must be made in the four forward fins t' mount t' aerials. Begad! Blimey! T' aerials are simply made by trimmin' t' cocktail sticks t' length. Well, blow me down! T' balsa strips are for t' fin mounts. Ahoy! These must be cut t' length, and then 3/32" slots cut out t' mount the fins. This isn't easy as t' parallel cuts required are very close together. Well, blow me down! A good metal straight edge t' control t' knife is a must. Avast! 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. Blimey! I painted t' entire surface with finishin' epoxy (zpoxy brand). Aye aye! This is a little different to normal epoxy in that it's much runnier, shiver me timbers, and almost completely odorless. Blimey! 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. Aye aye! Begad! I've since discovered that this can be prevented by lightly sandin' t' areas before application. Arrr! Arrr! Once dry a light sand overall be all that was required before the primer could be applied. A single coat o' primer and a single final coat were all that were required. Aye aye! Aye aye! T' instructions are pretty vague when it comes to paint schemes, me bucko, with just a single illustration and no decals. Aye aye! I searched the web and found schemes for t' British Army (olive) and Saudi Army (sand), but instead went with overall orange that seemed t' be indicated by t' package illustration.
* SPECIAL NOTE off o' RMR from Chuck Barndt, President o' T' Launch Pad
( 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 ...
