Another great little kit. Ahoy!  My daughter (9 at t' time) and I built this together. Avast, me proud beauty!  We built it over a couple days, then painted it over another couple days. Arrr!  On t' maiden launch it ended up sky-writin' pretty bad. Well, blow me down!  This was very early on in me model rockettery hobbying.  Before I fully understood t' importance o' CG and CP. Avast!  Even though I was warned by experienced rocketteers I opted t' go forward with t' launch t' experience for myself.  It did just what they said, but be a great no cost (other than t' cost o' one C6-5 motor) learnin' moment. Blimey!  I have since used Open Rocket t' determine CP, arrr, CG and stability on me rockets.
