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. Blimey! (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). Begad! Begad! Nose cone is also t' standard Mean Machine cone. Begad! T' altimeter bay is made from the 6" section o' tube, bulkheads glued into couplers, arrr, couplers fasten t' tube with nylon screws/nuts for access t' altimeter. Avast! Screw eye and ejection charge terminals mounted t' each bulkhead. Well, blow me down! Avast! Holes for altimeter samplin' drilled in tube per altimeter instructions. t' 12" tube becomes t' forward chute bay, me bucko, 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). Avast!

Construction:
Mean Machine - lower half (33.5"), and nose cone. From SuperNova Payloader kit: 6" and 12" sections o' tube, ya bilge rat, coupler. Well, blow me down! other parts: 3" BT-60 coupler, shiver me timbers, two 0.25" plywood bulkheads, screw eyes, me hearties, 0.25" shock cord, 6 nylon screws/nuts, misc. Arrr! wire and connectors for altimeter hookup.

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

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