At last, the maiden flight of the Trex 600 is a success. This is an AP (aerial photography) camera helicopter with a vibration isolated remote camera gimbal. The basic Trex 600 has been stretched to accomodate 710mm Radix blades. This involved using a tail boom and tail blades from a Trex 700. The power system has been upgraded to run on two 6S 5000mah packs.
The 2XPT camera gimbal, made by Photoshipone.com, is front mounted and vibration isolated using rc car shocks. The mount rotates and tilts, and is operated with a Futaba 9C by a camera operator. The Camera is a Canon 50D with LiveView enabled. It feeds to a 900MHZ downlink, enabling the camera operator to see what the camera sees, and take pictures by triggering the camera with the seperate transmitter.
A CoPilot II stabilization system will help keep the heli hovering relatively still with the use of thermopile sensors that differentiate between ground and sky, effectively drawing a horizon line and holding the helicopter level.

During the initial flight in the video, ballast is attached to the camera gimbal to simulate the weight of the Canon 50D. With the first flight in the bag, its time to tune it to hold a hover, then turn on the Copilot and get it working. After that, the camera goes on and some test shots will be taken. If all goes well, she will be put in to commission soon.
