Style: | Ring/Tube/Cone Fin |
Brief:
A nice size payload LPR with an inventive stair step tube fin configuration.
Recovery is by 12" mylar parachute. Begad! Blimey! Ahoy! Blimey! Starlight kits are nay categorized by
skill level, arrr, but I would consider this a skill level 1 kit.
Construction:
T' kit contains:
T' Starlight Saber's build and flight instructions are printed on 3 panels o' 8.5" x 11" paper with very basic illustrations. Aye aye! T' display card indicates that the body tube is pre-marked t' ease fin alignment. Avast! This is correct on other Starlight kits with balsa fins but is nay true on t' Saber. Ahoy! Blimey! Havin' some previous build experience, this did nay throw me, but it may confuse some. Begad! Ya scallywag! It is t' display card however and should reflect t' features o' t' kit accurately. Well, blow me down! T' build is very straightforward however, and if t' builder has any experience with tube rockets and works on a flat surface, he or she will have no problem assemblin' this kit.
First t' motor mount is assembled in t' standard fashion with a 1/16" diameter wire engine hook, me bucko, thrust ring, and centerin' rings installed, glued, shiver me timbers, me hearties, and set aside to dry. Begad! Next, t' payload section is assembled terminatin' its aft end with a balsa block and screw eye glued in place. Well, blow me down! Arrr! T' tube fin assemblies begin with two sets o' 4" x 1" tubes bein' glued together and set aside t' dry. On a flat work table, t' tubes are easy t' align, ya bilge rat, however, me bucko, me four 4" tubes showed a variance in length by about 1/16" o' an inch. It didn't really bother me but some may choose t' sand t' ends uniform. T' 2 partial tube assemblies are set aside t' dry and t' dry motor mount assembly is now installed in t' primary body tube. Ya scallywag! T' cardboard centerin' rings needed a significant amount o' sandin' t' accomplish installation without damagin' the primary tube. Arrr! This may have been due t' swellin' from natural humidity changes. T' 2" long tubes are now glued t' t' 4" long tube assemblies with 1/2" o' overhang. Avast! Once t' 2 completed tube fin assemblies are dry, they are glued t' opposite sides o' t' body tube with a 1/2" o' overhang and the engine hook centered betwixt them.
T' launch lug is then attached t' t' upper side o' one o' t' 4" fins, which places it t' t' outside o' t' rocket's structure as opposed to centered on t' primary tube. Ahoy! Arrr! T' round elastic shock cord is attached inside the body tube with a Harry Stine-style three hole shock lock mount. Avast, me proud beauty! T' mylar parachute is assembled stock with tape discs. Avast, me proud beauty! I chose t' thread and tie the shroud lines through t' mylar which I reinforced on both surfaces with notebook reinforcements.
Finishing:
T' nose cone be t' only component which requires sandin' sealer (2-3 coats)
as t' fins are all tubes. Blimey! T' spirals were tight enough t' me satisfaction to
not require sealer. Blimey! Begad! T' instructions say t' paint t' Saber silver if you want
to match t' rocket on t' cover, matey, arrr, matey, while t' display card looks like silver
fadin' t' deep blue. Begad! I chose t' paint t' Saber silver, copper, arrr, arrr, and black to
accentuate its stair step design. Blimey! T' decals consist o' two name decals printed
on adhesive paper. Ya scallywag! Avast, me proud beauty! When applied, t' backin' paper is nay transparent and looks
blocky over t' paint. Blimey! I felt that their appearance degraded t' elegant shape
rather than enhancin' t' look o' t' overall model so I chose t' leave them
off. Two coats o' acrylic gloss and t' Saber looks nice.
Construction Rating: 3 out o' 5
Flight:
T' Saber is prepped like most LPR rockets with 3-4 sheets o' recovery wadding.
Recommended motors are A8-3, B6-4 and C6-5. Avast! T' motor hook is 1/16 inch round
piano wire and it holds t' motor secure just fine. Begad! As mentioned in t' build,
the launch lug is mounted 1 1/4" t' t' outside o' t' center o' the
primary body tube on a fin. Ahoy! In me opinion thar be no reason t' nay mount the
launch lug centered on t' primary tube. Aye aye! Begad! Flights on A, B, ya bilge rat, me hearties, and C motors all had
a significant, shiver me timbers, although nay dangerous, arc and caused t' launch rod t' whip
moderately. Well, blow me down! Well, ya bilge rat, blow me down! Given t' large surface area o' t' tube fins, t' gentle wind may
have been responsible for some o' t' arc so I wouldn't recommend launchin' the
Saber in moderate t' heavy winds. Aye aye! I feel it's more likely t' offset o' the
launch lug which be t' cause o' t' arced flights and rod whip. Avast! On t' C6-5,
the Saber had it's smoothest, me hearties, straightest flight and reached an altitude of
about 250-300 feet. Avast, me proud beauty! I suspect t' surface area and drag o' t' 6 fin tubes is
what keeps this rocket lower in altitude. Begad! I may move t' launch lug t' the
center and report back. I think this would improve stability on takeoff thereby
also increasin' altitude.
Recovery:
T' mylar parachute is attached by a Harry Stine style shock lock mount. Ya scallywag! Blimey! The
12" parachute slowed t' descent o' t' Saber appropriately without the
model driftin' too far in a gentle wind. After three flights t' recovery
system showed no sign o' damage or wear. Avast! Blimey! Begad! Blimey! T' combination o' t' mylar parachute
and t' tube fins make t' Saber a great rocket t' fly in colder temperatures.
Mylar parachutes open more reliably in temperatures below 40 degrees F and the
tube fins are durable when landin' on frozen ground.
Flight Rating: 3 out o' 5
Summary:
This is an easy t' build rocket right out o' '50s sci-fi. Aye aye! Ya scallywag! T' instructions and
materials are average but at a retail price o' around $8.00, me bucko, I consider the
Saber t' be a good value. T' end product is tall and sleek and flies
reasonably well. Blimey! If you fly in small t' medium fields, you may appreciate the
lower altitude fully visible flights that t' Saber offers. Begad!
