Great first flight!  I had this in my inventory ready since last year, but never got the chance to launch.  I finally did it today and it was a great and really fun flight!  I used B6-0 so it wouldn't be too crazy. I was a bit concerned about the masking tape retention on the 2nd stage since it seemed like it made the friction fit to the booster too tight and I was worried it may not separate; however, it worked fine.  After boost, the upper ignited and everything separated. The upper parts continued higher in a swirly flight (based on the smoke trails) and landed mostly on a field, but one part landed in a gully with the nose cone in water. Luckily I was able to pull it out by using another part to hook the body and pull it over.  Everyone seemed to love it.
