    Hi everybody!

    Can someone please confirm that Firmware v4.01 allows the use of Graupner receivers (e.g. GR-16) on the M5?

    Using PPM you should be fine.

    Sorry Patrick I don't run Graupner equipment since leaving the MK stuff behind. Perhaps Ben can give an update.

    Hey guys,

    i also had problems because i tried to use my MX-16 with a GR-12L.

    Here is the solution that worked for me and the reason for my problem:

    Graupner has its own philosophy of ppm or sum-signal. There are 3 different version of their sum-signal called SUMO (sum-signal-out, analog), SUMI (sum-signal-in, analog) and SUMD (sum-signal, digital). The only one that gives a analog ppm signal is SUMO. The receiver „GR-12L" doesn’t have the ability to send SUMO (analog) but can send SUMD (digital).
    I took another receiver (the Graupner „GR-16“) wich is able to send SUMO-signal and it worked out direct. The mapping-settings you wrote depend on the pre-settings you make in your transmitter (what action goes to wich channel…).

    Everything works out perfectly an with the new Akira-Firmware it got a weapon...
