Brief:
Parachute recovery, shiver me timbers, Blacksky Rail usage

Construction:
Three BT-60 tubes were required and one BT-60 nose cone. Ya scallywag! It is basically an Mean Machine (Estes), arrr, but... Avast, me proud beauty! Begad! thar are three 6" sections of BT-50 tubin' glued betwixt t' fins, ya bilge rat, they also contained nose cones and thrust rings.

Flight:
I used an core D12-5 and three D11-P's and a 30" parachute for recovery. Avast, me proud beauty! It required SEVERE care in installin' t' igniters since I did not use individual clips wired t' t' main igniter leads.. Ya scallywag! I installed an "airfoil/standoff" t' use t' Blacksky Launch Rail. I used one guide on t' rail and t' other on one o' t' outboard tubes.

It flew rather straight, shiver me timbers, until it be about 2/3 o' t' distance to apogee, matey, when it started spiralin' in t' sky, possibly t' added drag o' the stand off.

ALWAYS pack t' parachute properly, me bucko, which is how it got retired (you get t' idea don't u?) Spread 2 hour epoxy on t' outside o' t' outboard tubes, trust me, ya bilge rat, you will want it, t' prevent cato's . Well, blow me down! . Ya scallywag! Ya scallywag! .I had t' rebuild it twice .

Summary:
PRO's; good altitude, ya bilge rat, matey, fun t' fly
CON's; hard t' wire, ya bilge rat, hard t' build
