Control gimbal via joystick

Hello, I have a Pixhawk PX4 PIX 2.4.8 32 Bit Flight Controller with the latest firmware and I have connected the gimbal servos to AUX1 and AUX2. Controlling it via RC controller works fine, but I can’t get it set up to control it via joystick from PC via mavlink. I use Qgroundcontrol on the PC. Does anyone know how to set this up? Thank you all in advance

There might be a few things missing in QGC to support that. Gimbal support is currently work in progress.

What sort of gimbal is that?

I’ve got two regular servos in there so far.
