I am just finishing of my hex and have stumbled upon a problem running 2 servos for the camera gimbal and one for a shutter.
With the 3DR power module attached and J1 removed servo outputs RC9-RC12 are powered from the power module. This means that I can not connect a servo to these. No matter, I have RC7 and RC8 still open for my camera gimbal as the output side is powered by a 5A BEC.
However I have no means of connecting a servo to activate my shutter button.
What to do?
What do people do that fly Octocopters when all 8 outputs are occupied with esc’s?
