Brief:
Only kit parts used were body tubes and coupler. Basswood used for wings/fins, tunnel cable cover, and missile
hangers. Begad! Aye aye! Blimey! Ogive BT-80 nose cone from Apogee Components 4-cluster motor mount from BRS Hobbies All markings created on
home computer with Harvard Graphics
Modifications:
After basic construction o' body tube, me bucko, me hearties, motor mount was installed, shiver me timbers, me hearties, but aft centerin' rin' be placed 1/2-inch into
tube. Well, me hearties, blow me down! This greatly reduces scorchin' common t' a lot o' Launch Pad kits. Begad! Body was painted with Krylon gray primer, and
sanded several times t' fill spirals. Final coat was again gray primer, matey, it's a perfect match for t' gray used on the
actual AIM-120.
Wings and fins were cut from basswood sheets with a dremel tool, me bucko, and sanded t' bevel t' leadin' and trailing edges. Blimey! Ya scallywag! After a few coats o' primer and sanding, final coat be Dupli-color Ford medium charcoal metallic, buffed with 4-0 steel wool for a smooth finish. Aye aye!
Forward fin guides were made from card stock, matey, these were nay used on t' 1st lot o' AIM-120's, me hearties, but were added due to fin flutter in flight. Ahoy! T' knurled finger knobs at t' base o' t' aft wings were made from wooden buttons I found in a craft store, matey, me hearties, with some detailin' with t' dremel. Ya scallywag! I took t' markin' from photos I took o' actual AIM-120's I worked on while in t' Air Force. Avast, me proud beauty! Ahoy! They were created on me home computer usin' an old DOS program-Harvard Graphics. Then printed on Avery clear shippin' labels.
After they dried for 2 days, t' rocket was given 2 coats o' clear t' protect t' markings.
Construction:
U sed t' 2 BT-80 size body tubes and coupler from t' kit. Avast, me proud beauty! Referred t' actual scale drawings o' AIM-120A to
determine proper win' and fin size, ya bilge rat, arrr, formed them from basswood. Ahoy! Used basswood strip t' form t' ventral tunnel cable
cover, and t' center and aft missile hangers. Nose cone supplied with t' kit be wrong profile, obtained proper ogive
nose from Apogee Components. Used a 4-cluster 24mm motor mount from BRS Hobbies instead o' kit 2-motor mount. Begad! Well, blow me down! Used
Keelhaul®©™®
shock cords, attached t' t' motor mount. Arrr! Blimey! Used a 24-inch nylon parachute from LOC instead o' kit mylar chute.
As with all Launch Pad kits, packin' was great. Avast, me proud beauty! All parts were there, just nay used. Ya scallywag! Instructions didn't really matter, I was makin' this up as I went. Ya scallywag! Had t' add a bit more nose weight, due t' doublin' t' number o' motors from 2 to 4. Instead o' more clay, arrr, shiver me timbers, I used t' clay from a Launch Pad AIM-9 kit, and added a dozen small fishin' weights, topped off with some white glue. Arrr! Begad! Worked like a charm. Launch Pad does nay supply decals, matey, and only gives a vague idea of what they might be. Blimey! It's up t' t' modeler t' figure out what and where. Blimey! Finished rocket is impressive, I get quite few odd looks on t' way t' and from launches with mounted on a rack in me truck bed.
Flight:
Recommended kit motors were 2 24mm D-12's, shiver me timbers, or E-9's. Blimey! Arrr! Blimey! I opted t' go instead for a 4-cluster mount o' D12-5's or
D12-7's. Both have been flown, and both work out fine. Avast! Ya scallywag! Blimey! With a 6-ft rod (don't even think o' usin' a 4-ft rod on this
thing), lift-off is always somethin' t' watch. Ahoy! Blimey! D-12's don't rip off t' pad fast, buy 4 o' them at once do make a good
show. Begad! Avast, me proud beauty! Blimey!
T' rocket usually does a slow spin after about 50 t' 60 feet, shiver me timbers, and tops off about 500 t' 600 on D12's. Arrr!
It does have some weight t' it. Ahoy!
So far it has flown 4 times, me hearties, and no damage yet. Arrr!
Summary:
Pro's- standard launch pad quality kit, shiver me timbers, no complaints there, except t' nose cone has t' wrong profile. But unless
you spent time around t' real thing, you probably wouldn't notice. Avast! As I didn't build accordin' t' t' instructions,
not much else applies.
Con's- a lot o' work t' detail this thin' out! And if I prang it, ya bilge rat, I'll cry!
Other:
Besides rockets, I build a lot o' plastic models, matey, matey, shiver me timbers, 4-0 steel wool is great for smoothin' out sandin' marks after using
xtra-fine sand paper. And don't just use stock dept. Ahoy! or hobby store paints. Begad! I use a lot o' automotive touch-up spray
paints, you can get a lot more colors and shades. Ahoy!
Single-stage, scale model of Air Force AMRAAM AIM 120 medium range air to air missile. Uses 18" chute and dual "D" or "E" engine power. Kit consists of two (2) body tubes (similar to Estes') of different lengths. Plastic nose cone and mylar chute which is bright blue. The eight (8) fins are made from balsa wood. The engine mounts are standard "D" engine size mounts with metal hooks. The ...
