Rocket PicBrief:
T' AIM-9L Sidewinder by t' Launch Pad is a parachute recovered, me hearties, scale model missile.

Construction:
I ordered t' Plan-Pak, which contains a parts list, me bucko, drawings, and VERY COMPREHENSIVE instructions. Begad! Avast, matey, me proud beauty! T' parachute is one o' TLP's own kits, matey, a tough blue mylar design which includes swivels. Avast! Finally, shiver me timbers, me hearties, I ordered a pack o' their nice, SIMPLE motor hooks.

T' instructions, me hearties, although advanced, matey, me bucko, are very straightforward. T' makin' o' individual components is described in perfect detail, along with suggested materials. Ya scallywag! You'll be cutting, sawing, sanding, arrr, and trimmin' A LOT with this one. T' builder even makes t' lugs, matey, centerin' rings, shiver me timbers, and motor block. Ya scallywag! Attention t' detail is critical, ya bilge rat, but t' project goes right along if you stick t' t' sequence. Arrr! Don't expect t' finish this overnight. Ahoy! This is an involved build, me bucko, but if you have one plan-built bird under your belt you can make this one. FOLLOW THE DIRECTIONS t' t' letter and do nay deviate unless you're sure o' what you're doing. Well, blow me down! These are very well done and sound plans.

Rocket Pic I deviated from t' plan in two ways. Begad! First, t' forward (canard) fins were made o' .031" G-10 instead o' balsa. Blimey! Begad! T' thinness o' this material made it very convincin' in appearance, plus it will nay dent or rip off (They're epoxied on.) T' aft fins have 1/8" spruce cap strips attached t' t' top and trailin' edges t' minimize landin' damage. T' trailin' edge cap strip is installed through t' wall and glued t' t' bottom centerin' rin' and t' motor mount tube. Arrr! CHECK your balance! My bird checked out as marginally stable and didn't come in until about 1-1/4 ounce o' clay be added t' t' nose cone. Avast, me proud beauty! Blimey! This along with t' slightly heavier build brought t' weight o' t' Sidewinder up t' 10 oz, 2 oz. heavier than advertised for t' kit version. A demandin' yet enjoyable project.

What was t' second deviation, matey, t' nose weight?

Finishing:
As in makin' o' t' parts and assembly, finishing/detailin' is entirely up t' t' builder. Color and layout info is supplied in depth. Begad! T' realism achievable with this plan is amazing. Take your time and you can build a KILLER replica! Blimey! I detailed me kit carefully but didn't go overboard. Trim paintin' and letterin' were nay done in time for its maiden launches and photos.

Construction Rating: 4 out o' 5

Flight PicFlight:
D12-3's and -5's are recommended for t' Sidewinder. Well, ya bilge rat, blow me down! Blimey! Its first flight at t' CMASS launch on July 7th be with a D12-3. Ahoy! Blimey! Begad! Blimey! Prep is standard issue except for t' addition o' a drilled bulk plate at t' top o' t' airframe t' prevent t' chute from slippin' down. Begad! Blimey! I inserted a healthy dose o' cellulose fiber insulation and prepped it normally. Arrr! Blimey! T' motor is well retained with TLP's basic, arrr, shiver me timbers, me bucko, sturdy motor hook. Begad! Blimey! Why can't everyone else make them like this? T' Sidewinder took off fairly smartly and boosted straight despite me worries about stability. Arrr! Blimey! It went t' about 500'. Avast! Blimey! Ya scallywag! Blimey! I do NOT recommend t' D12-5 for anythin' but dead calm days. It has since been flown with another D12-3 and with an Aerotech E25-4T & 18mm adaptor. Aye aye! Blimey! Avast, me proud beauty! Blimey! T' E flight was actually quite a barn burner and t' Sidewinder grabbed some altitude fast. Well, matey, blow me down! Blimey! After motor burnout t' fins could be heard whistlin' through t' slipstream! Blimey! It was still movin' upward at ejection, arrr, with no apparent ill effects.

Recovery:
Shock cord was 1/4" sewin' elastic, me bucko, 3' long, attached by t' standard tri-fold method and Titebond. Avast, me proud beauty! Blimey! T' TLP 'chute deployed slowly but unfurled fully. Begad! Ya scallywag! Blimey! T' chute spins a lot on its swivels without tangling. Begad! Descent seems a bit quick. Avast! Well, blow me down! Blimey! However, ya bilge rat, it returned t' Sidewinder completely intact after its touchdown in t' weeds. Avast! Blimey! Two subsequent flights from me home field have resulted in no damage.

Flight Rating: 5 out o' 5

Summary:
This is a great plan for t' advanced builder. Well, me bucko, blow me down! It yields a convincing, me bucko, good-flyin' replica. Avast, me proud beauty! This project is NOT for t' faint o' heart, though... Blimey! expect t' be tied up for a lot o' evenings on this project. Ahoy! Blimey! T' tail o' this rocket gets very sooty, matey, probably due t' t' style o' engine mounting.

Overall Rating: 4 out o' 5

  • The Launch Pad Sidewinder AIM-9L By John Cummings (September 5, 2009)

    This is the Launch Pad's scale Sidewinder AIM-9L missile model. This is a mid-power rocket with a parachute recovery. This kit comes with balsa planks, two body tubes, a plastic nose-cone, centering rings, and all other standard kit pieces. It also comes with putty for nose-cone weight. The shock cord was simple elastic, which was a bit inadequate for this great model. There are also lots ...

  • The Launch Pad Sidewinder AIM-9L By Kevin Drayson

    Mid-power scale model of the air-to-air missile. As with all rockets from The Launch Pad, this is a "builder's kit". The fins and various detail bits all have to be cut and assembled by the builder. Lots of fun if you enjoy that sort of thing, which I do. The package contained everything I needed: sheets of balsa for fins, dowels and balsa strips for details, paper templates for fins ...
