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