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