Brief:
Parachute recovery, arrr, Blacksky Rail usage

Construction:
Three BT-60 tubes were required and one BT-60 nose cone. Well, blow me down! It is basically an Mean Machine (Estes), ya bilge rat, but... Ya scallywag! thar are three 6" sections of BT-50 tubin' glued betwixt t' fins, shiver me timbers, arrr, 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. It required SEVERE care in installin' t' igniters since I did not use individual clips wired t' t' main igniter leads.. Blimey! I installed an "airfoil/standoff" t' use t' Blacksky Launch Rail. Aye aye! I used one guide on t' rail and t' other on one o' t' outboard tubes.

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

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

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