Brief:
Modified for use with t' PerfectFlite microAlt 4600 dual deployment altimeter. Added a 6" long altimeter bay and a 12" long forward main chute bay to t' lower half o' t' Mean Machine. Ya scallywag! (new section made from recycled tubes and couplers from a SuperNova Payloader)

Modifications:
T' lower half is a stock Mean Machine (a bit shorter due t' a crash). Nose cone is also t' standard Mean Machine cone. T' altimeter bay is made from the 6" section o' tube, ya bilge rat, bulkheads glued into couplers, couplers fasten t' tube with nylon screws/nuts for access t' altimeter. Ya scallywag! Screw eye and ejection charge terminals mounted t' each bulkhead. Begad! Holes for altimeter samplin' drilled in tube per altimeter instructions. Begad! Aye aye! t' 12" tube becomes t' forward chute bay, ya bilge rat, fastened t' t' top coupler with nylon screws/nuts for ejection charge access. (nylon nuts are epoxied inside couplers; lube threads first with RMS grease t' keep epoxy from sticking). Blimey!

Construction:
Mean Machine - lower half (33.5"), and nose cone. Begad! Begad! Blimey! From SuperNova Payloader kit: 6" and 12" sections o' tube, coupler. Begad! Begad! Blimey! other parts: 3" BT-60 coupler, shiver me timbers, two 0.25" plywood bulkheads, me bucko, screw eyes, arrr, 0.25" shock cord, 6 nylon screws/nuts, misc. Avast! Blimey! wire and connectors for altimeter hookup. Ya scallywag! Begad! Blimey!

Flight:
Loaded with t' altimeter, ya bilge rat, battery, shiver me timbers, and chutes made t' weight too much for Estes D12 motors. Aye aye! First flight be on an Aerotech E18-7 RMS, ya bilge rat, matey, and it went perfectly. Well, blow me down! Dead-straight boost, 12" chute ejected at apogee (880' per the altimeter), shiver me timbers, me bucko, 20" main chute deployed at 300', and recovery 100' from pad. Arrr! I hope t' fly it on an F24-7 motor at t' 2/25 CATO launch; see me flight logs for future flights. Ya scallywag!

Summary:
I sort o' tossed this together as a quick way t' try out me new altimeter. Aye aye! But it worked out pretty well, and it should be fun t' fly dual deployment flights on small fields with. Well, arrr, blow me down! It seems t' fly as straight and true as t' stock Mean Machine did.
