Tx in mode 2.

No signal from Rx is recognized by the board unless I'm in ESC calibration.

I can calibrate ESCs, but can't arm the system afterwards. Also, I now don't get a GPS response.

Just swap over the cables from roll and yaw.

What mode is your Tx in?

Comment by Dan Skaggs on July 4, 2013 at 6:45pm
Mike, Tx is set to acro. Throttle bar was only moved in MP by throttle, but Rudder was moved by roll & roll was by rudder. That's why I initially thought receiver wires were wrong, but they checked out right (see Logan's comment below). Now I can't get board/ESCs to initialize.

Bo, good thought, but I read the same note about trimming throttle - tried it but no change.

Have you got your Tx set to Heli by mistake, instead of Acro?

In your radio calibration window on mission planner, when you move throttle is only the throttle moving. This window with the moving bars should aid you in sorting out which channels are doing what.

When you move the rudder to the right is the rudder bar going to max?

I had problems arming, but it worked when selecting arm in the mission planner. Then I read that the throttle trim needed adjusting so that the down & to the right for four seconds really cuts the throttle to zero.

good luck.  bo

Logan, thank you for your help. However, the hook-up you suggested is what I have on my set-up, so I guess that's not my issue. What's odd is that the board did power up initially and I went through the initial RC set-up with calibrating the sticks; got the ESCs calibrated; all motors & servo worked, although the servo  seemed connected to the throttle inputs. Also, I could not arm or disarm the copter - copter only responded to ESC calibration process. I also started to notice  that when powering up  the copter the board LEDs don't seem to work to show initialization is complete. So I don't think the board is powering up with connection to copter only (Tx/Rx/Battery & no usb). Board powers and connects to computer fine w/ USB only, as when installing firmware.

@Dan Skaggs

Assuming you are using the AR8000 receiver the hookup should be as follows.

Aile to Input 1

Elev to Input 2

Thr to Input 3

Rudd to Input 4

Aux 1 to Input 5

You will probably want to reverse Aileron, Elevator, and Rudder from the RC controller.

I just bought my APM 2.5 from DIYdrones to hook it up to my simple tricopter. Can anyone help with a wiring diagram to connect my spectrum receiver properly to the board? I'm using the power module to power the APM board. I've loaded the firm ware to the APM, hooked up the motors and servo per the wiki instructions, calibrated the escs, but can't get the motors to arm. Also, after calibrating, the throttle seems to move te servo for yaw as well as increase throttle, yet the yaw, roll & pitch stick movements have no effect. Any help is appreciated.

@Rob, any pics would be useful.

Thanks.
