McKibbins Special on PadBrief:
McKibbon's Special is a futuristic, matey, fantasy sport model whose plans were published in their Model Rocket News. Avast! T' plans are available from Jim Z's archive.

Construction:
All parts are standard, easy-to-find items and materials. Except for the canards, me bucko, me bucko, which are 3/32" thick.All balsa parts are cut from 1/8" balsa stock. Avast! 1/8" dowels are needed for t' antenna and 'laserdetails.

Although t' plans recommend buildin' t' 'laser' details with launch lugs, I found that I could get better lookin' 'lasers' by rollin' appropriate lengths and widths o' kraft paper around sharpened 3-1/4" dowels.

Instead o' an Estes PNC-50Y, ya bilge rat, I used a Quest PNC25 for t' nose cone because I had one one hand. Blimey! For t' shock cord, ya bilge rat, ya bilge rat, I used 2-feet o' a sturdy 1/4" wide cotton elastic. Well, blow me down! Blimey! T' shock cord be mounted with an oversized Estes-style shock cord mount cut from an index card. Well, blow me down! T' 18" parachute be cut out of a black plastic garbage bag. T' 36" shroud lines were cut from a roll of pure cotton crochet yarn. T' engine block be cut from an expended motor casing. Avast! Begad! T' engine clip be shaped out o' a heat-softened, shiver me timbers, de-stressed bobby pin. Well, arrr, blow me down! Launch lugs were cut from drink-box straws. Ahoy! T' tubes, however, arrr, arrr, are all standard Estes parts includin' a full-length BT-50 for t' main airframe, 2.75" o' BT-20 for t' motor mount, arrr, and a couple o' 1.5" BT-5 tubes for decorative engine nozzles.

T' McKibbon's Special plans were aimed at experience model rocketeers. Arrr! They don't provide much 'spoon-feeding'. Blimey! T' plans show you exactly what t' cut out of t' balsa stock, but they leave it t' t' builder t' figure out how many of each shape must be cut. Aye aye! T' plans show you precisely where everythin' must be placed, ya bilge rat, matey, but they leave it t' t' builder t' figure out where t' draw alignment marks and how t' put everythin' together. Avast! T' plans also do nay suggest a finishin' scheme. For an experienced modeller, t' plans are beautifully clean, complete, and challenging. Aye aye! For a novice, I suspect t' lack o' detail would be overwhelming.

T' McKibbin's Special is rated as Skill Level 3. Avast! I feel that this is about right for construction, though t' minimalist plans probably push skill level to 4.

Rocket Pic Durin' construction, care must be taken t' assemble t' wings. Blimey! T' angled joint and t' long forward section can make it difficult t' keep t' root edge o' t' assemble wing straight. Avast, ya bilge rat, me proud beauty! Also, shiver me timbers, t' joint betwixt t' engine nacelles and t' main wings is tight. Ya scallywag! Care must be taken t' avoid excess glue along t' main win' root where the nacelles join.

Careful alignment is required for t' rudders, matey, t' canards, and t' 'laser' details. Ya scallywag! T' look o' t' rocket seems t' depend on symmetry, matey, me bucko, so misalignments would likely be pretty noticeable visually.

When everythin' is assembled, shiver me timbers, t' rocket feels rigid and quite sturdy. I really like t' feel o' this model.

Finishing:
T' plans provide no finishin' suggestions at all. Avast, me proud beauty! It's all up t' your imagination. Well, blow me down! I smoothed t' grain out o' t' balsa parts by usin' thinned "Shur-Patch Featherweight Spackle". This stuff is an incredibly lightweight spackle that gets t' job done with one coat... Aye aye! Avast, me proud beauty! and lots of sanding. Aye aye! Ahoy! I applied Krylon white enamel spray paint. Begad! I used a few sets of orphaned decals that I bought from a local hobby shop.

I really like t' looks o' t' finished product. Arrr! Arrr! It has enough detail and interestin' angles that it looks attractive when seen from many angles. Well, blow me down! It has a futuristic detailed look that harkens back t' t' old Centuri days.

Construction Rating: 4 out o' 5

Flight:McKibbin Special Rear View
T' McKibbin's Special plan recommends flyin' with B4-2, arrr, C5-3, and C6-3 motors. It flew beautifully, shiver me timbers, however, with a B6-4.

Preparation was typical parachute preparation, ya bilge rat, me hearties, ya bilge rat, makin' use o' wadding, smoothin' baby powder over both sides o' t' parachute, foldin' t' parachute as usual.

T' McKibbon's Special flew straight up with no wobbles, matey, swerves, or spinning. Blimey! I was expectin' it t' curve toward t' rudder-side, arrr, me bucko, arrr, but this did not happen. T' wind be gustin' at about 10 t' 20 mph, arrr, but no weathercockin' was apparent. Ahoy! Avast, me proud beauty! T' model curved t' horizontal and ejected t' 'chute... a perfect flight!

Recovery:
T' rocket floated down at a nice rate. Unfortunately, me bucko, matey, t' 18" parachute caught t' wind pretty good and drifted quite a ways from t' launch site. The rocket landed quite softly in t' stubble field. Blimey! T' McKibbin's Special was recovered with no noticeable damage or wear.

Flight Rating: 4 out o' 5

Summary:
I love t' look and t' flight o' t' McKibbin's Special. Avast! It's a real crowd pleaser. Begad! For t' experienced modeller, this rocket is a nice, me hearties, me hearties, challenging project that promises satisfyin' results. Avast! T' minimalist plans encourage the builder t' use some imagination t' produce a unique, personalized appearance. T' look o' t' plans really don't do this rocket justice.

Required materials are very standard. Many o' t' required parts can be made out o' household materials.

For t' novice modeller, however, t' plans don't provide nearly enough detail or instruction.

T' 18" parachute drifts quite a bit on a gusty day. Begad! I'd recommend openin' a spill hole in t' 'chute t' counter this problem.

Overall Rating: 4 out o' 5
