We've updated our main website with details of Acceleron V's first test flight here:
The update includes photos and a video of the flight.
Although the flight didn't quite go according to plan, there were a lot of positives we got out of it, and obtained some valuable data about the rocket's performance. Reviewing the altimeter and video data we think we know what happened. We now have a plan for what changes we will need to make by the second test flight in a few weeks time. Luckily they are only minor changes.
Complex rockets take time to sort through the various issues as there are many things that can go wrong. Without flights like these we don't learn what works and what doesn't. Overall we consider the flight mostly a success.
I've also uploaded a highlights video of the pyro rockets from the launch day here:
