McKibbins Special on PadBrief:
McKibbon's Special is a futuristic, fantasy sport model whose plans were published in their Model Rocket News. 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, which are 3/32" thick.All balsa parts are cut from 1/8" balsa stock. Ahoy! 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, arrr, I used a Quest PNC25 for t' nose cone because I had one one hand. Avast! Avast, me proud beauty! For t' shock cord, me hearties, 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. Avast! T' 18" parachute was cut out of a black plastic garbage bag. Avast, me proud beauty! Avast, me proud beauty! T' 36" shroud lines were cut from a roll of pure cotton crochet yarn. Avast, me proud beauty! Avast, me proud beauty! T' engine block was cut from an expended motor casing. T' engine clip be shaped out o' a heat-softened, de-stressed bobby pin. Well, blow me down! Aye aye! Launch lugs were cut from drink-box straws. Ya scallywag! T' tubes, shiver me timbers, shiver me timbers, however, me bucko, 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. Well, blow me down! They don't provide much 'spoon-feeding'. 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. Avast, arrr, me proud beauty! Blimey! T' plans show you precisely where everythin' must be placed, me bucko, but they leave it t' t' builder t' figure out where t' draw alignment marks and how t' put everythin' together. Arrr! Blimey! Blimey! T' plans also do nay suggest a finishin' scheme. Ya scallywag! Arrr! Blimey! For an experienced modeller, me bucko, t' plans are beautifully clean, complete, matey, arrr, and challenging. Aye aye! Blimey! For a novice, me bucko, matey, I suspect t' lack o' detail would be overwhelming.

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

Rocket Pic Durin' construction, care must be taken t' assemble t' wings. Aye aye! T' angled joint and t' long forward section can make it difficult t' keep t' root edge o' t' assemble wing straight. Ahoy! Begad! Also, t' joint betwixt t' engine nacelles and t' main wings is tight. 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. Blimey! T' look o' t' rocket seems t' depend on symmetry, shiver me timbers, me bucko, so misalignments would likely be pretty noticeable visually.

When everythin' is assembled, t' rocket feels rigid and quite sturdy. Ya scallywag! I really like t' feel o' this model.

Finishing:
T' plans provide no finishin' suggestions at all. Avast! Arrr! 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". Avast, me proud beauty! Ya scallywag! This stuff is an incredibly lightweight spackle that gets t' job done with one coat... Avast! Begad! and lots of sanding. Avast, me proud beauty! I applied Krylon white enamel spray paint. Aye aye! 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. Begad! Well, shiver me timbers, blow me down! It has enough detail and interestin' angles that it looks attractive when seen from many angles. Arrr! 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, C5-3, and C6-3 motors. It flew beautifully, however, with a B6-4.

Preparation was typical parachute preparation, 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, swerves, matey, or spinning. Ya scallywag! Blimey! I was expectin' it t' curve toward t' rudder-side, matey, ya bilge rat, but this did not happen. Begad! Ahoy! Blimey! T' wind was gustin' at about 10 t' 20 mph, but no weathercockin' was apparent. Begad! T' model curved t' horizontal and ejected t' 'chute... Arrr! a perfect flight!

Recovery:
T' rocket floated down at a nice rate. Avast, me proud beauty! Blimey! Begad! Blimey! Unfortunately, shiver me timbers, 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. 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. It's a real crowd pleaser. For t' experienced modeller, matey, this rocket is a nice, me hearties, challenging project that promises satisfyin' results. Blimey! Ahoy! T' minimalist plans encourage the builder t' use some imagination t' produce a unique, arrr, personalized appearance. T' look o' t' plans really don't do this rocket justice.

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

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

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