Hi there, first of all, let me clear something, I am very new to this DIY Quad thing, so, might be saying or doing something totally wrong and stupid, please excuse that.
I have a bit of problem with setting up the Mini APM pro. Actually the setup process with PC was OK, except it didn't recognize the compass in the flight controller, but that is a separate issue all together.
I am not certain whether I have done the connections on the controller and receiver correct. I am using a Radiolink R9D receiver with the A9T transmitter. I am posting relevant pictures so you can see how I have done the connections.
Also wants to make a note that I have calibrated the ESC's seperately during setup and all is done, but strangely the when I put the throttle up to max, nothing happens, but the motors start to get the current
once I put the throttle down. It should work the other way around, isn't it? also the relevant motor from the ESC spins right sometime, and left sometime..!! Also once I setup the connections like this, nothing happens.
Given that I am new to these, I am totally confused guys. Any help will be greatly appreciated. This is my first DIY quad and I am stuck. Probably the hardware selections was not right, learning...learning....
Thanks and expecting some help coming soon.
see http://copter.ardupilot.com/wiki/connecting-the-apm2/ for wiring diagram. You need to wire each channel ie. A9D CH1 to CH1 APM Inputs, A9D CH2 to CH2 inputs APM etc.. i.e. using PWM
this link show how to put the A9D in PWM mode http://www.helipal.com/radiolink-r9d-2-4ghz-9-ch-s-bus-receiver.html
