With the extra mass of control systems, camera etc. the launch sequence was slow and very dramatic. The rocket lifted off the launch guide and arced off away from us about 15 degrees from vertical, sending the shock waves from the exhaust straight towards us with maximum intensity (Photos and video coming soon in the mean time see http://www.stuff.co.nz/science/3356662/One-giant-leap-for-Amberley-paddock).
The purpose of the launch was to test the roll control, a first step towards full directional control. As the rocket accelerated up into the sky, we could see the control system 'hunting' - holding the average angle steady but oscillating around the target angle. We just need to cut back on the gains to increase stability and it should stay rock solid in the next launch.
Initial estimates put the rocket up 700m, but the altimeter data (shown below) indicates an apogee of 550m and peak velocity of 380 km/h.
The drogue chute deployed successfully, and the rocket was seen descending through the clear blue sky with the bright yellow chute trailing behind. We couldn't see any evidence of the main chute opening, and the rocket disappeared down behind some trees.
After an extensive search, the rocket was found with the assistance of some locals who saw it descend. The main chute had deployed, but was tangled and had not opened properly. Despite the hard landing, the on-board equipment has survived better than expected, with the main controller and actuators back up and running. The CNC machined aluminium fins are in need of panel beating/re-machining. My camera that went along for the ride has finally met its maker (after a series of wild adventures that it miraculously survived).
