There is a very noticible effect from the launch rail at the beginning. The rail was a BlackSky rail made from aluminum but it was reinforced with a length of pipe.
The longitudinal axis sensor shows that the rocket had pitched over considerably before the parachutes were deployed. This matches my visual observations as the rocket appeared to be layed out horizonally at deployment. At the time of launch the wind was blowing at about 10 to 15 mph. In spite of the wind and very low launch velocity the rocket was once again very stable and flew perfectly straight up.
Although this flight was very interesting in that it was close enough that everyone could see everything that happened, I don't care to repeat it. For such a large and heavy rocket it was much too low and slow for me.
