setting up different flight modes with a Spektrum DX7



This is how it worked for my DX7,

I use various switch combinations of the FLAPS and the GEAR switch which will give you 6 modes;

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


  • Press SCROLL DOWN + SELECT to access the programming mode
  • Go to the "Travel Adjust" menu with the SCROLL UP/DOWN button
  • click the SELECT button till you reach "Flap", then set "Flap" to "U 65%" and "D 65%" (INCREASE/DECREASE button, you'll have to move the "Flap" switch to select between "U" and "D", this means put the switch in "N" position (away from you) to program the "U" value and move the switch to the "2" position for the "D" value)
  • Leave "Gear" on 100% - 100%
  • Go to "Mix1" (with the SCROLL UP/DOWN button)
  • go into the menu of "Mix1" by pressing the INCREASE button
  • Select "Ger" > by pressing the INCREASE button
  • press SELECT to jump to the second position and elect  > "Flap" on by pressing the INCREASE button
  • press SELECT
  • Set rate to "19%" and "31%" (with the INCREASE/DECREASE button, you'll have to put the GEAR switch in the "0" position for the first value and into the "1" position to set the second value)
  • press SELECT
  • Set SW to "on" by pressing the INCREASE button
  • Leave Offset at "0"

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 selected if the "Flaps" switch is on "N" (away from me), no matter if the "Gear" 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.


(this is based on the blog post by Nick Wadman, I just adopted the programming description for a DX7)

    the instructions for setting up the DX7 for 6 different flight modes, but using only one channel can be found here:

    6 modes / one channel

    Hi - sorry about the missing information, I did the setup a while ago and tried to remember how to do it in order to write the tutorial. I actually redid the whole setting again on my remote to make sure nothing is left out in my description, but it must have remembered those settings ...

    Sorry Felix, I appreciate your efforts in re-writing the instructions, but they still do not work if some other settings on the transmitter are not correct.

    Fortunately, I spent a few more hours on it last night, and discovered some behind the scenes conflicts, and now  I can set the configuration according to your instructions.

    In your third instruction to set UP at 65% and DN at 65%, you can only select the DN setting with the flap switch if in the [FLAP SYS.] menu you have the AUTO function set to INH. If the AUTO function shows a number, reducing the number to 0% does not cut it. You have to press CLEAR to get back to INH. Now you will find the 3 position flap switch will change the word in the top right display can be switched between NORM,MID, and LAND with the flap switch.

    And that aint all. In SYSTEM MODE, under [INPUT SELECT] , the FLAP function has to be set to SYSTEM.

    Now your instructions seem to work, and that they do can be easily confirmed by operating the switches and watching the servo monitor display.


  • Hein - Let me recommend to you that you stay with the five modes, and not go for the six. The reasoning is just as Felix says. I have been on the flight line with a pilot who did just this, and he found that when things went wrong, confusion reigned, and he could not quickly achieve manual mode in the few seconds he had left before disaster.


  • Hi Felix,

    Looking forward to your reply about using 1 ch for 6 modes.  It could be very much interesting.

    great - I didn't know about this one. I will try the setup for my DX7 tomorrow and write a detailed instruction like above.

  • Did you know this one: http://diydrones.com/forum/topics/six-flight-modes-can-be-done

    Works great with DX7 without wasting the Gear channel.

    all right - updated the above description, hope it works now

  • Fantastic - great to see this addressed.

    I do want to achieve the five options just as you have.

    However, I followed the steps very carefully, and I just don't get the same result.

    Clearly there are other settings that must be selected before the sequence you present will work.

    The first stumbling block is in setting the flap to 65% up and 65% down. Moving the flap switch just does not select the down option to allow the down position to be set.

    The second is that I have no idea how or where Trim is set to Inh.

    I would very much appreciate a little more info.

    Thanks. Jack.
