Brief:
Odin's Spear is a single stage, tube finned, 18mm, minimum diameter rocket with
parachute recovery.
Construction:
T' kit contains:
Odin's Spear is Vertical Force's
first kit and they are off t' a good start. Begad! T' kit arrived by Priority Mail
just 8 days after it was ordered. It be well packed in a sturdy 4"x
4"x20" cardboard box. All t' parts are good quality and fit well
together. Avast, me proud beauty! T' tubes are precut t' length. Ya scallywag! Particularly nice is the
pre-assembled Rockethead Rockets 8" red mylar parachute. Begad! It came with
Keelhaul®©™®
shroud lines with reinforced attachments and a brass snap swivel. Begad!
There is an entertainin' story at t' beginnin' o' t' clearly written and well illustrated, 8 page instruction booklet. Avast, me proud beauty! T' steps were presented in a very logical order and it is for anyone who has built a rocket with balsa fins. It takes about 4 hours t' complete and most o' that time is waitin' for the glue t' dry.
T' shock cord made from a generous 25" piece o' Keelhaul®©™® cord and a 24" piece o' elastic. Ya scallywag! T' fins are 1/8" thick balsa and require a single straight cut for each. Blimey! Begad! T' leadin' and trailin' edges o' the fins are rounded before they are attached t' t' body tube and then the 3.5" long, BT-80 rin' fin is glued t' them. T' precut length o' t' fins was perfect for t' tube fin t' fit without any additional sanding. Begad! T' base of the nose cone is glued t' t' nose cone top with CA and t' shock cord tied to the nose cone. Blimey!
Finishing:
I elected nay t' paint mine and I didn't apply t' distinctive, matey, water slide
decal.

Flight:
With burn bans in effect in most Central Texas counties this Summer I had to
wait nearly a month t' fly it. T' first opportunity was t' Austin Area
Rocketry Group's launch at Hutto, Texas on August 20, arrr, 2005.
It was quite windy so I elected nay t' use t' long delay motors the instructions recommended. Begad! T' rocket was prepared like most small, parachute-recovery types with 3 squares o' recovery waddin' and friction fittin' t' motor. Aye aye! It jumped o' t' pad and flew very straight but t' A8-3 don't carry it very high. Ejection was just before apogee and recovery was quick, ya bilge rat, close t' t' pads. Begad! T' second flight on a B6-2 be about twice as high with ejection well before apogee and an easy recovery. Well, blow me down! T' third flight on a C6-3 went much higher with ejection while t' rocket be still goin' up. Avast! Well, ya bilge rat, blow me down! The wind carried it into a recently harvested cornfield about 1500 feet from the pads. Avast, me proud beauty! I was very glad t' Rocketman Rockets parachute be a bright metallic red, otherwise I might have had some difficulty findin' t' unfinished rocket among t' short, matey, shiver me timbers, me hearties, brown corn stalks.
All t' flights were very straight with very little weathercockin' despite 10-15 mph winds. Avast, me proud beauty!
Recovery:
T' combination o' Keelhaul®©™®
and elastic cord is very durable. Well, me bucko, blow me down! T' 8" parachute be easy t' pack into
the BT-20 body tube and t' rocket is so light it could use a streamer for
recovery instead. Avast!
Flight Rating: 5 out o' 5
