Aircraft Type: Cinestar 8 Gimbal Type: Cinestar 3-axis Radian Type ( 1, 2 , 3 axis) 3 axis Gimbal Power source: 11.1v Gimbal Radio Type: Spektrum DX8 Radian Communication Protocol (S.Bus, PPM, PWM, Spektrum): Spektrum Connections: Change these to match your setup Roll Sensor: Port 1. Pan sensor 2. 3. To Tilt sensor 4. To Roll servo Tilt Sensor: Port 1. Roll sensor 2. 3. 4. Tilt servo Pan Sensor: Port 1. 2. Battery 3. Roll sensor 4. Pan servo The port on the bottom of the Pan sensor is connected to the Spektrum receiver Symptoms: When the gimbal is powered up the roll and pan axis seem to work OK. But the tilt axis is having problems. I have no control of the tilt axis through the transmitter (radio) - if I move the tilt control the tilt axis does not respond. However it will often suddenly point the camera at the sky without any input from the transmitter. It also appears to try to stabilise the camera tilt in only one direction - in that it will tilt the camera up if the heliocpter tilts forward, but will not tilt the camera down when the helicopter tilts back (see my video). Leaving the camera pointing at the sky. Everything worked fine for the first flight, but halfway through the second flight the camera suddenly pointed at the sky and the tilt axis stopped working - we hadn't made any configuration changes. Steps taken to resolve: I have checked the Radian settings through the Radian USB tool. The tool can see the tilt control input from the transmitter, and the channel appears correctly assigned. I have also re-installed the latest firmware 1.03 on the tilt radian, and reset to default settings. None of this has had any effect. I've attached a video of the problem and screen shots of each of the Radian's settings. Theo Ps. Tried to upload video of my problem but browser told me it was too large. Is there a maximum file size for upload on the forum?
