setting up 6 different flight modes on a Spektrum DX7 using just one channel

These instructions explain how to set up a Spektrum DX7 transmitter for 6 different flight modes, using just the 3 position Flaps switch (in combination with the Rudder switch). This way you'll use just one channel for the flight modes and leave the Gear and Aux2 channel open ...

(note that you have to use the DX7 in "airplane mode", not in "heli mode" to fly a quadcopter)

 

  • switch on your remote while pressing SCROLL DOWN and SELECT
  • go to "D/R Switch Sel" menu (with the SCROLL UP/DOWN button)
  • select "Com Rudd" by pressing the INCREASE button
  • go to the "Input Select" menu (with the SCROLL UP/DOWN button)
  • press select until you reach "Flap:", make sure it is set to "System" (you can change the setting with the INCREASE button)
  • press SELECT
  • set "Flap Trim" to "Inh" by pressing the INCREASE button
  • switch off the remote
  • switch on the remot
  • Press SCROLL DOWN + SELECT to access the programming mode
  • Go to "Mix1" (with the SCROLL UP/DOWN button)
  • go into the menu of "Mix1" by pressing the INCREASE button
  • Select "Flap" > by pressing the INCREASE button
  • press SELECT to jump to the second position and select  > "Flap" by pressing the INCREASE button
  • press SELECT
  • Set rate to "+100%" and "-50%" (with the INCREASE/DECREASE button, you'll have to put the FLAP switch in the "N" position for the first value and into the "2" position to set the second value)
  • press SELECT
  • Set SW to "Mix" by pressing the INCREASE button
  • press SELECT
  • set offset to "10" by pressing the INCREASE button
  • Go to "Flap Sys" menu (with the SCROLL UP/DOWN button)
  • set Flap Norm = UP to "46%" (with the SCROLL UP/DOWN button)
  • press twice SELECT
  • set Flap Mid = DN to "8%" (with the SCROLL UP/DOWN button)
  • press twice SELECT
  • set Flap Land = DN to "100%" (with the SCROLL UP/DOWN button)
  • press twice SELECT
  • set Auto Land to Inhibit (with the SCROLL UP/DOWN button)

connect now your APM to the Ardupilot Mega Planner, go to the setup page and assign different flight modes to the switch combinations of your remote.

 

I like to have easy access to the simple mode (just to get very quick out of a difficult situation) which is the reason why I have two switch combinations programmed for simple mode. I have set it the way that simple mode is always selected if the "Flaps" switch is on "N" (away from me), no matter if the "Rudder" switch is on or off. This way I have just 5 modes accessible, but I can very easy and quick switch back to simple mode.

    i dont know why... I have reset the settings... its still the same...

  • Chris Kreuzer March 12, 2012 at 3:07am

    I have the same issue like "Hein du Plessis"

    if the flaps sw is in pos 1 and the rudder sw is in  pos 1 im exacly in the middle

    if the flaps sw is in pos 1 and the rudder sw is in  pos 0 im a little bit left from the middle - really just a little bit

    And I dont reach the maximum in the flap channel!!

    If i set the flaps sw to N and the rudder sw in pos 1 i had the highest value in flap channel but not the maximal

    Here a picture with all modes

    Hi Felix

    My values were correct, but you were spot on, I simply had to delete my model and recreate the profile and I could access all 6 modes! Except... mode 5 (Mix pos 1, Flaps pos N) does not want to change. It stays in Manual mode. I'm not too worried about it, but just curious as to why.

    Hi

    can you confirm that you have set all the "%" values as shown in the description above?

    If this doesn't help, try to reset all the settings for the selected model on your remote and start again with the steps outlined above (maybe you have somewhere something set, which influences your settings).

    Hope this helps

    Wonderful, but I can only get 4 modes. I've made a short clip to indicate the signal range of the combinations: https://www.youtube.com/watch?v=0myIPY_iCbM

    It's as if I don't have enough spread through the channel. Can anybody help?

    Thanks Felix and thank you Jiri. I couldn't figure out why this wasn't working until I read your comment. Now it works perfectly!

    Tried this, was not working for me (only two modes with GEAR switch were working) and then I found out I had to swap GEAR and AUX1 cables on my AR7000 receiver.

    Now works perfectly.

    Thanks !!!

    Great Post!!  Minor correction to it.

    >> set Auto Land to Inhibit (with the SCROLL UP/DOWN button)

    Actually you need to press the "clear" button to get INH, not the UP/DOWN button.

    Thank you for the info.
