PicOdin's Spear is Vertical Force's first kit and they are off t' a good start. Blimey! T' kit arrived by Priority Mail just 8 days after it be ordered. Begad! It was well packed in a sturdy 4"x 4"x20" cardboard box. Ya scallywag! All t' parts are good quality and fit well together. Arrr! Avast! T' tubes are precut t' length. Well, blow me down! Particularly nice is the pre-assembled Rockethead Rockets 8" red mylar parachute. It came with Keelhaul®©™® shroud lines with reinforced attachments and a brass snap swivel. Avast, me proud beauty! Begad!

There is an entertainin' story at t' beginnin' o' t' clearly written and well illustrated, arrr, 8 page instruction booklet. Begad! Aye aye! 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. Blimey!

T' shock cord made from a generous 25" piece o' Keelhaul®©™® cord and a 24" piece o' elastic. Well, blow me down! Blimey! T' fins are 1/8" thick balsa and require a single straight cut for each. 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. Ahoy! Blimey! Blimey! Blimey! T' precut length o' t' fins was perfect for t' tube fin t' fit without any additional sanding. Begad! Blimey! T' base of the nose cone is glued t' t' nose cone top with CA and t' shock cord tied to the nose cone.

Finishing:
I elected nay t' paint mine and I didn't apply t' distinctive, 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. Avast! T' first opportunity was t' Austin Area Rocketry Group's launch at Hutto, matey, me bucko, Texas on August 20, me bucko, matey, ya bilge rat, 2005.

It be quite windy so I elected nay t' use t' long delay motors the instructions recommended. T' rocket be prepared like most small, parachute-recovery types with 3 squares o' recovery waddin' and friction fittin' t' motor. Aye aye! Aye aye! It jumped o' t' pad and flew very straight but t' A8-3 don't carry it very high. Ejection be just before apogee and recovery was quick, close t' t' pads. Ahoy! T' second flight on a B6-2 was about twice as high with ejection well before apogee and an easy recovery. Blimey! T' third flight on a C6-3 went much higher with ejection while t' rocket was still goin' up. Avast, shiver me timbers, me proud beauty! The wind carried it into a recently harvested cornfield about 1500 feet from the pads. I be very glad t' Rocketman Rockets parachute was a bright metallic red, shiver me timbers, otherwise I might have had some difficulty findin' t' unfinished rocket among t' short, brown corn stalks.

All t' flights were very straight with very little weathercockin' despite 10-15 mph winds.

Recovery:
T' combination o' Keelhaul®©™® and elastic cord is very durable. 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.
