While attendin' our first LDRS this year, me son Chris, shiver me timbers, matey, me wife Kathy, arrr, and I, witnessed t' most impressive display o' large rockets we had ever seen. Avast! Avast, me proud beauty! T' launch site in Orangeburg, arrr, South Carolina was unlike anythin' we have access t' in Pennsylvania. Begad! T' wide open, matey, arrr, flat, grassy launch site was almost too good t' be true. Begad! Couple that with a 10,000 foot above ground level FAA waiver, matey, and you have a high power rocketeer's dream. Aye aye! Well, blow me down! Throughout t' four day event, we watched rockets o' every conceivable size and weight, shiver me timbers, matey, powered by a variety o' motors from "A" through "M", ya bilge rat, take t' t' clear, blue, shiver me timbers, South Carolina skies. Ahoy! Aye aye! When t' announcement was made at Sunday night's banquet about the location o' LDRS 20, Chris and I almost immediately started makin' plans to attend.
In addition t' plannin' t' trip t' Lucerne Dry Lake, me bucko, California, I started plannin' a rocket project t' take along. Since I achieved me Level 2 certification this past August 5th, a powerful, shiver me timbers, ya bilge rat, 54mm motor based, dual-deployment rocket be a must. Aye aye! I decided t' modify a plan I had been workin' on for some time, arrr, which resulted in a 4 inch diameter, ya bilge rat, 8 1/2 foot long rocket. Aye aye! T' six-fin design which originally was called the "Six-shooter", matey, had now become "Six Appeal".
T' rocket was built usin' 4" PML
Quantum tubin' and a PML nosecone. Begad! T' fins were cut from .093" G10
fiberglass and will go through t' airframe and mount t' a PML extended
Quik-Switch 54mm motor tube. Ya scallywag! Well, blow me down! I cut t' fin slots myself by markin' t' tube,
drillin' a 1/8" hole at each end o' t' slot, and usin' a steel straight
edge and an X-acto knife. T' Quantum tubin' was only slightly more difficult
to cut than normal phenolic tubing.
A 10" section o' coupler tubin' and
3/16" plywood be used t' build t' avionics bay that will house a Missile
Works RRC2 altimeter. Aye aye! T' altimeter, by t' way, was won in a raffle at the
LDRS 19 banquet. Blimey! T' ejection charge holders were made usin' PVC pipe plugs
epoxied t' each end that will hold Robby's Rockets ejection canisters.
T' recovery system is a 20" Sky Angle parachute for t' drogue and a 52" Sky Angle parachute for t' main. Ya scallywag! Twenty-one feet o' tubular nylon for shock cords at each end o' t' avionics bay, along with Nomex heat shields and shock cord protectors.
After primin' and paintin' with gloss paint, arrr, I applied custom made vinyl graphics. Ya scallywag! Ya scallywag! T' finished rocket weighs in a just under 10 lbs empty. Avast! T' picture (above and right) was taken at LDRS XX just prior t' a successful first flight, to 5,958 feet on an Aerotech K550.
