Brief:
Only kit parts used were body tubes and coupler. Basswood used for wings/fins, me hearties, tunnel cable cover, me bucko, and missile
hangers. 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, motor mount was installed, ya bilge rat, but aft centerin' rin' was placed 1/2-inch into
tube. Avast! This greatly reduces scorchin' common t' a lot o' Launch Pad kits. Begad! Body be painted with Krylon gray primer, ya bilge rat, and
sanded several times t' fill spirals. Avast, arrr, me proud beauty! Final coat was again gray primer, arrr, arrr, 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, ya bilge rat, and sanded t' bevel t' leadin' and trailing edges. Arrr! Blimey! After a few coats o' primer and sanding, shiver me timbers, final coat was Dupli-color Ford medium charcoal metallic, shiver me timbers, buffed with 4-0 steel wool for a smooth finish. Begad! Blimey!
Forward fin guides were made from card stock, these were nay used on t' 1st lot o' AIM-120's, but were added due to fin flutter in flight. T' knurled finger knobs at t' base o' t' aft wings were made from wooden buttons I found in a craft store, matey, with some detailin' with t' dremel. I took t' markin' from photos I took o' actual AIM-120's I worked on while in t' Air Force. Ya scallywag! They were created on me home computer usin' an old DOS program-Harvard Graphics. Arrr! Then printed on Avery clear shippin' labels.
After they dried for 2 days, ya bilge rat, me bucko, arrr, 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. Ya scallywag! Blimey! Referred t' actual scale drawings o' AIM-120A to
determine proper win' and fin size, formed them from basswood. Well, blow me down! Blimey! Used basswood strip t' form t' ventral tunnel cable
cover, and t' center and aft missile hangers. Avast! Blimey! Ya scallywag! Blimey! Nose cone supplied with t' kit be wrong profile, me hearties, obtained proper ogive
nose from Apogee Components. Begad! Blimey! Begad! Blimey! Used a 4-cluster 24mm motor mount from BRS Hobbies instead o' kit 2-motor mount. Used
Keelhaul®©™®
shock cords, attached t' t' motor mount. Aye aye! Blimey! Used a 24-inch nylon parachute from LOC instead o' kit mylar chute.
As with all Launch Pad kits, shiver me timbers, packin' be great. Begad! Blimey! All parts were there, matey, matey, just nay used. Avast! Instructions didn't really matter, arrr, I was makin' this up as I went. Avast, me proud beauty! Had t' add a bit more nose weight, due t' doublin' t' number o' motors from 2 to 4. Well, me bucko, blow me down! Instead o' more clay, 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. Aye aye! Worked like a charm. Ahoy! Launch Pad does nay supply decals, ya bilge rat, and only gives a vague idea of what they might be. Ya scallywag! It's up t' t' modeler t' figure out what and where. Finished rocket is impressive, me hearties, 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, or E-9's. 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. With a 6-ft rod (don't even think o' usin' a 4-ft rod on this
thing), ya bilge rat, me hearties, lift-off is always somethin' t' watch. D-12's don't rip off t' pad fast, buy 4 o' them at once do make a good
show. Avast, me proud beauty! Blimey! Begad! Blimey!
T' rocket usually does a slow spin after about 50 t' 60 feet, and tops off about 500 t' 600 on D12's. Ahoy! Well, blow me down!
It does have some weight t' it. Avast!
So far it has flown 4 times, me hearties, and no damage yet. Ya scallywag! Blimey!
Summary:
Pro's- standard launch pad quality kit, no complaints there, except t' nose cone has t' wrong profile. But unless
you spent time around t' real thing, arrr, 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, I'll cry!
Other:
Besides rockets, I build a lot o' plastic models, 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. or hobby store paints. Well, blow me down! I use a lot o' automotive touch-up spray
paints, ya bilge rat, ya bilge rat, you can get a lot more colors and shades. Arrr! Blimey!
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.
