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