Receiver Wiring Setup

Could someone please tell me which wire goes where (from spektrum receiver to APM); specifically, which output from the receiver goes to the "pitch" input on the APM?  Normally with spektrum, pitch in Heli mode is output on Aux 1, so does Aux 1 from receiver go to pitch input on APM?  If so, then where does the "gear" receiver output go?

To summarize:

Spekturm Output                                      APM 2.5 Input

Throttle                                                     Input 8 (Thr)

Aileron                                                      Input 1 (Ail)

Elevator                                                    Input 2 (Ele)

Rudder                                                      Input 4 (Rud)

Gear                                                         ???

Aux 1                                                        ???

Aux 2                                                       Input 6 (Aux 2)

Aux 3                                                       Input 7  (Aux 3)

With my Aux 1 (Spektrum pitch) output plugged into Input 3 on the APM, I get no pitch movement on the servos.  Also, when I go into the Heli setup screen, I get an error message (see first attached pic) and my setup screen looks like this (see second attached pic).

  • Just an update; I go the folllowing wiring to work with mission planner:

    Spekturm Output                                      APM 2.5 Input

    Throttle                                                        Input 8 (Thr)

    Aileron                                                         Input 1 (Ail)

    Elevator                                                        Input 2 (Ele)

    Rudder                                                         Input 4 (Rud)

    Gear                                                            Input 5 (Aux 1)

    Aux 1                                                           Input 3 (Pitch)

    Aux 2                                                           Input 6 (Aux 2)

    Aux 3                                                           Input 7 (Aux 3)

  • I think you are right and using the right info. At the time of the Wiki composition, there was no Spektrum information (I address this below).

    I am going to delete my first response -- don't want anyone to get confused (like me).

    That's amazing, I couldn't find the Trad Heli document you are using. Mea Culpa!

    There is no link off the path: Instructions --> Traditional Helicopters (but the Table of Contents takes you to the same place as the next line below)

    Rather, the path is: APMCopter --> Table of Contents -->(scroll down) Traditional Helicopters --> (pick your section)

    Thanks for pointing it out because I have a 450 Clone and want to employ APM on..and I will be using Spektrum also.

    I did read below the section you linked to..

    NB: We need info on channel settings for other radio systems!

    So even the Devs haven't used Spektrum. You are on the bleeding edge Jim!

    What TX /RX are you using? I know Robert L uses Futaba (go figure -- he is one of the Go-To guys for trad heli).
