This notional missile be t' latest in t' AGM-65 Maverick air t' ground missile systems. Begad! Buildin' on t' successful AGM-65H with active radar seeker, the "I" model incorporates GPS guidance with active radar terminal guidance. Arrr! Aye aye!

T' idea for this model came when I noticed that t' fins on t' Estes AGM-57 Heatseeker kit were very similar t' those o' t' Maverick. There are only three fins on t' Heatseeker so you'll need two kits. Arrr! Ahoy! But since the Heatseeker also comes with a set o' "excess" Nike-Smoke shaped fins, you still have a pair o' complete models. Ya scallywag! I should point out that I did nay set out t' build a precise scale model, matey, ya bilge rat, but only capture t' look o' a Maverick. Begad! Begad!

After some quick scalin' computations from data obtained from t' Missile Index page, I determined that a BT-60 tube was t' closest t' scale. Blimey! Blimey! I used an 11 inch length, a little longer than scale t' provide more stability and less nose weight in t' finished model. Arrr! Blimey! T' nosecone be t' same as that o' t' Estes Baby Bertha kit (two o' these come in t' Estes NC-60A nosecone pack). Begad! Blimey!

T' engine mount is 18mm and uses t' standard two paper centerin' rin' with engine hook. Ahoy! I took care t' align t' two centerin' rings so they were just wide enough for t' fin slots t' fit betwixt them. Begad! Begad! T' motor is recessed one-half inch into t' body tube. Begad! Begad! A Keelhaul®©™® strin' is tied and epoxied t' t' MMT for shock cord retention. Aye aye! Shock cord is about two feet o' 3/8 inch sewin' elastic. Ahoy! Aye aye!

Mountin' t' fins was t' greatest challenge, shiver me timbers, but was fairly straight forward. Avast! First, I printed out a fin alignment wrap in VCP havin' set t' fin width equal t' t' thickness o' t' Heatseeker fin tabs. Ahoy! I also made sure the root chord length I entered into VCP be longer than t' Heatseeker fin. Avast! Blimey! I taped t' fin alignment wrap securely t' t' body tube, me bucko, shiver me timbers, alignin' t' bottom of the wrap where I needed t' base o' t' fin slot. Begad! Well, blow me down! Blimey! I carefully measured the positions o' t' Heatseeker fin slots and colored these locations on t' wrap with a Sharpie. Ya scallywag! Blimey! Then it was just a matter usin' a Dremel tool with three cuttin' wheels t' cut out t' fin slots usin' t' markings on t' fin alignment wrap as a guide. Avast! Fins were attached usin' plastic model cement followed by gap fillin' CA along t' root edges and resulted in sturdy attachment. Begad! Blimey! Fore and aft launch lugs were added t' resemble mountin' points on t' actual missile.

After priming, I used Krylon Smoke Gray gloss for t' body and Color Place gloss black (97 cents from WalMart!) for t' nose cone. T' decals were from the Heatseeker kit and went on very easily for pressure sensitive decals, matey, they are much thinner than those I've used in t' past. Blimey! Well, blow me down! T' stripes were made from self-adhesive Monokote. Ahoy! Arrr! Finished with two coats o' Color Place clear. Avast! Aye aye! I like the look o' t' glossy finish, matey, me hearties, although t' real thin' would have a flat finish. Aye aye! Ya scallywag!

Rocket PicModelin' clay was added t' t' nose t' ensure stability - always a necessity in modelin' missiles with a warhead. T' model sims t' just over 500 feet on a C6-5 and nearly 200 feet on B6-2. Begad! Begad!

First flight was in cold, blustery conditions on an Estes B6-2 with a 9 inch nylon parachute. Aye aye! Boost seemed weak with t' rocket archin' into t' wind to maybe 125 feet. Avast, matey, me proud beauty! Ejection occurred past apogee with nose down. Avast, me proud beauty! Nose cone ejected but charge wasn't strong enough t' eject t' chute. Avast, me proud beauty! Landed without damage close to t' pad. Begad! Well, blow me down! (Did I mention that I soaked both ends o' t' body tube with thin CA?) Second flight be another B6-2. Perfect - straight boost t' roughly 200 feet with ejection nearly at apogee. Nylon chute caught t' wind but landed safely within t' range. Begad! Can't wait t' try this rocket in good weather on the C6-5!
