Very nice Corpse. I remember my first 2 stage, Estes Apache 2. Man that thing flew great. Still have the booster section, that's all.
The best one I ever had was my Omega, I can see it arcing out of sight.....dang that was a nice one.
I still have my original Commanche 3, but got a new one and gave it a little different color scheme. That is also a fun one to fly, highly recommended, but I have to drive 100 miles to launch at Lucerne or I'll never get it back.
I currently have 2 that haven't flown, Magnum and a Custom Lightnin'. Both attempted, but the Magnum booster engine CATO'D and sent it sideways, really weird, nice flame out though. I have been able to fix. The Lightinin' was poorly made, I dunno must a been distracted, so as a result of a short coupler connection I had to tape the booster to the main stage and it burned right thru the booster. Not a good flight, but fins are in tact and certainly very fixable.
If you want another fun 2 stager, the CC Express I recommend as well. It flies great. Will post pictures of Commanche 3 later but here's my Magnum.
