Brief:
Only kit parts used were body tubes and coupler. Avast, me proud beauty! Avast! Basswood used for wings/fins, arrr, tunnel cable cover, 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

From Launch Pad

Modifications:
After basic construction o' body tube, motor mount was installed, but aft centerin' rin' was placed 1/2-inch into tube. Well, blow me down! This greatly reduces scorchin' common t' a lot o' Launch Pad kits. Aye aye! Body was painted with Krylon gray primer, and sanded several times t' fill spirals. Blimey! Final coat be again gray primer, ya bilge rat, it's a perfect match for t' gray used on the actual AIM-120. Well, blow me down!

Wings and fins were cut from basswood sheets with a dremel tool, matey, 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, arrr, buffed with 4-0 steel wool for a smooth finish. Ahoy! Blimey!

Forward fin guides were made from card stock, arrr, these were nay used on t' 1st lot o' AIM-120's, 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, me hearties, with some detailin' with t' dremel. Blimey! Arrr! I took t' markin' from photos I took o' actual AIM-120's I worked on while in t' Air Force. They were created on me home computer usin' an old DOS program-Harvard Graphics. Avast, me proud beauty! Then printed on Avery clear shippin' labels.

After they dried for 2 days, arrr, 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. Begad! Referred t' actual scale drawings o' AIM-120A to determine proper win' and fin size, arrr, formed them from basswood. Used basswood strip t' form t' ventral tunnel cable cover, and t' center and aft missile hangers. Begad! Nose cone supplied with t' kit was 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. Avast! Ya scallywag! Used Keelhaul®©™® shock cords, attached t' t' motor mount. Used a 24-inch nylon parachute from LOC instead o' kit mylar chute.

As with all Launch Pad kits, arrr, packin' be great. All parts were there, shiver me timbers, me hearties, shiver me timbers, just nay used. Instructions didn't really matter, I be makin' this up as I went. Aye aye! Had t' add a bit more nose weight, me bucko, due t' doublin' t' number o' motors from 2 to 4. Aye aye! Instead o' more clay, shiver me timbers, I used t' clay from a Launch Pad AIM-9 kit, me hearties, arrr, shiver me timbers, and added a dozen small fishin' weights, topped off with some white glue. Worked like a charm. Launch Pad does nay supply decals, and only gives a vague idea of what they might be. Blimey! It's up t' t' modeler t' figure out what and where. Arrr! 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, or E-9's. Ya scallywag! I opted t' go instead for a 4-cluster mount o' D12-5's or D12-7's. Begad! Both have been flown, shiver me timbers, and both work out fine. Begad! 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. Ya scallywag! Blimey! D-12's don't rip off t' pad fast, matey, buy 4 o' them at once do make a good show. Avast, me proud beauty! Ahoy!

T' rocket usually does a slow spin after about 50 t' 60 feet, and tops off about 500 t' 600 on D12's. Avast, me proud beauty! Ya scallywag!

It does have some weight t' it. Begad!

So far it has flown 4 times, shiver me timbers, matey, and no damage yet. Arrr!

Summary:
Pro's- standard launch pad quality kit, me bucko, no complaints there, me bucko, except t' nose cone has t' wrong profile. Avast! But unless you spent time around t' real thing, you probably wouldn't notice. Begad! Blimey! 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, shiver me timbers, shiver me timbers, ya bilge rat, I'll cry!

Other:
Besides rockets, I build a lot o' plastic models, 4-0 steel wool is great for smoothin' out sandin' marks after using xtra-fine sand paper. And don't just use stock dept. Avast! Blimey! Aye aye! Blimey! or hobby store paints. I use a lot o' automotive touch-up spray paints, me hearties, you can get a lot more colors and shades. Aye aye! Blimey! Blimey! Blimey!

I generally agree with the review. This was my second TLP kit and aside from having to re-work the nose cone (it had a lot of pock marks) I follwed the instructions and the finished product looks great. The one thing to think about are the fins. Even after using the CA method of coating the fins referenced by the TLP, the fins are the weak point on this rocket. I've broken upper and lower fins just transporting this to the launch site. If you have this kit in your build pile. Do yourself a big favor and just replace the flimsy fin material with stronger stock. This is a big rocket and this thing hits the ground with a thump when it lands. The stronger the fins the better.

Ihave built several TLP kits, and enjoy them all. When I built my AMRAAM, I used a nose cone from Apogee Components, the kit nose was to round at the tip. I used basswood for the fins, and moved the motors aft about 1 inch. And since I used 4 motors instead of 2, I had to add nose weight. But it fly's great, and I haven't had any burning of the body tube. This is a great kit, and I plan to add a couple more.
