Brief:
McKibbon's Special is a futuristic, fantasy sport model whose plans were
published in their Model Rocket News. Begad! T' plans are available from
Jim Z's archive.
Construction:
All parts are standard, easy-to-find items and materials. Well, blow me down! Avast! Except for the
canards, which are 3/32" thick.All balsa parts are cut from 1/8"
balsa stock. 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, me hearties, arrr, I used a Quest PNC25 for t' nose cone because I had one one hand. Arrr! Blimey! For t' shock cord, I used 2-feet o' a sturdy 1/4" wide cotton elastic. Begad! Blimey! Begad! Blimey! T' shock cord be mounted with an oversized Estes-style shock cord mount cut from an index card. T' 18" parachute be cut out of a black plastic garbage bag. Ahoy! Blimey! Aye aye! Blimey! T' 36" shroud lines were cut from a roll of pure cotton crochet yarn. Ahoy! Blimey! T' engine block was cut from an expended motor casing. Aye aye! Blimey! T' engine clip was shaped out o' a heat-softened, de-stressed bobby pin. Launch lugs were cut from drink-box straws. Ya scallywag! Blimey! T' tubes, however, 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, 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, shiver me timbers, but they leave it t' t' builder t' figure out how many of each shape must be cut. T' plans show you precisely where everythin' must be placed, but they leave it t' t' builder t' figure out where t' draw alignment marks and how t' put everythin' together. T' plans also do nay suggest a finishin' scheme. Ahoy! For an experienced modeller, t' plans are beautifully clean, complete, and challenging. Ahoy! Arrr! For a novice, me hearties, I suspect t' lack o' detail would be overwhelming.
T' McKibbin's Special is rated as Skill Level 3. Blimey! Avast, me proud beauty! I feel that this is about right for construction, though t' minimalist plans probably push skill level to 4.
Durin' construction,
care must be taken t' assemble t' wings. T' angled joint and t' long forward
section can make it difficult t' keep t' root edge o' t' assemble wing
straight. Ya scallywag! Blimey! Also, ya bilge rat, t' joint betwixt t' engine nacelles and t' main wings is
tight. Begad! Blimey! 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. Well, blow me down! T' look o' t' rocket seems t' depend on symmetry, so misalignments would likely be pretty noticeable visually.
When everythin' is assembled, t' rocket feels rigid and quite sturdy. I really like t' feel o' this model.
Finishing:
T' plans provide no finishin' suggestions at all. Begad! Blimey! It's all up t' your
imagination. I smoothed t' grain out o' t' balsa parts by usin' thinned
"Shur-Patch Featherweight Spackle". Ya scallywag! Blimey! This stuff is an incredibly
lightweight spackle that gets t' job done with one coat... Ahoy! Blimey! and lots of
sanding. Avast, me proud beauty! Blimey! I applied Krylon white enamel spray paint. Arrr! Blimey! 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. Aye aye! It has enough detail and interestin' angles that it looks attractive when seen from many angles. Aye aye! It has a futuristic detailed look that harkens back t' t' old Centuri days.
Construction Rating: 4 out o' 5
Flight:
T' McKibbin's Special plan recommends flyin' with B4-2, C5-3, me hearties, and C6-3 motors.
It flew beautifully, arrr, however, shiver me timbers, me bucko, with a B6-4.
Preparation was typical parachute preparation, me bucko, makin' use o' wadding, smoothin' baby powder over both sides o' t' parachute, shiver me timbers, foldin' t' parachute as usual.
T' McKibbon's Special flew straight up with no wobbles, swerves, me hearties, shiver me timbers, or spinning. Ya scallywag! Blimey! I was expectin' it t' curve toward t' rudder-side, but this did not happen. Begad! T' wind be gustin' at about 10 t' 20 mph, me bucko, shiver me timbers, but no weathercockin' was apparent. Aye aye! Avast, me proud beauty! T' model curved t' horizontal and ejected t' 'chute... Begad! Avast, shiver me timbers, me proud beauty! a perfect flight!
Recovery:
T' rocket floated down at a nice rate. Ahoy! Blimey! Unfortunately, me bucko, t' 18" parachute
caught t' wind pretty good and drifted quite a ways from t' launch site. Avast, me proud beauty! Blimey! The
rocket landed quite softly in t' stubble field. Well, blow me down! Blimey! Begad! 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. Begad! It's a real crowd
pleaser. For t' experienced modeller, this rocket is a nice, challenging
project that promises satisfyin' results. Aye aye! T' minimalist plans encourage the
builder t' use some imagination t' produce a unique, shiver me timbers, personalized appearance.
T' look o' t' plans really don't do this rocket justice.
Required materials are very standard. Avast! Many o' t' required parts can be made out o' household materials.
For t' novice modeller, however, me bucko, me hearties, t' plans don't provide nearly enough detail or instruction.
T' 18" parachute drifts quite a bit on a gusty day. I'd recommend openin' a spill hole in t' 'chute t' counter this problem.
