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