Spektrum DX8 with APM 2.5 Controller Need Help Setup

Can someone be kind enough with a DX8 and APM 2.5 configuration email me a setup file I can load into my DX8?

I am having a lot of problems understanding how to configure my Spektrum to work with my ArduCopter Hexa-B setup. Ideally a step by step guide setting up the DX8 for 6 Flight Modes would be very helpful. I am currently stuck until I can get some more detailed help on the concepts involved and nothing would help more than an actual setup file I can load via into my DX8.

I have already read through the current links for DX8 6 Position setup by Arndt but unfortunately it seems aimed more towards those users who are already familiar with configuring the DX8...

  • I am kinda new to the Multiroter groups and i have actually built a few frames from scratch and i am not brand new but new to the APM and DX8 setup first flight controller was KK2.5.1 then i moved to Multiwii 2 pro and now i am getting in to APM. I have the DX8 and APM 2.8 which is the same as the 2.5 and 2.6  just Comps and some transistor changes. any way would you have the SPM  file that i can import in to my DX8 to configure my controller Im quit lost and am in need of some majer quadcopter wisdom

  • You need to create a custom mix.  I have mine set up so the F-Mode switch (3 pos) and the gear switch (2 pos) control my modes.  With the gear switch in one position, you have the 3 flight mode postions, and with the gear switch in the other position, you have the 3 flight mode positions, giving you 6 possible flight modes.

    The first step is to make sure your switches are set correctly in the system setup menu under Sw Select.  F-Mode should be "Inh" and Gear should be "Gear".  This will allow you to create a mix on the gear channel (channel 5 on Spektrum) using the F-Mode switch to activate the mix.

    Then go to mixing in the function list for the model you are programming.  Scroll to "Mix 1", change the master/slave to "GER > GER".  Change the Rates to "-56%" and "-46%", leave Offset at "0%", Trim "Inh", Sw to "FM1".  Basically what all this means is when F-Mode is in position 1, the gear channel will only be at 56% of the travel BELOW midpoint when the gear switch is off, and 46% of the travel ABOVE midpoint when the gear switch is on.

    Now go to "Mix 2" and do the same thing but make the rates -90% and -80% respectively, and the Switch to FM2.  Now when the F-Mode switch is in position 2 the gear channel will only be at 90% of the travel BELOW midpoint when the gear switch is off, and 80% of the travel ABOVE midpoint when the gear switch is on.

    There is no mix needed for F-Mode position 0, because we want full travel on the gear channel in that position.

    The percentages I used may not be exactly what you need, but they should be close.  You can monitor the channel on the Flight Mode setup screen of the Mission Planner and tweak as necessary.

    I hope this helps. 

  • I have a DX8 and 2.5 and it works pretty good.
    Just need some tuning on the APM side.
    If I can figure out how to download the setup then I can send it to you.

  • I am working on a similar problem which I encountered last night. Did you ever make any progress on your DX8 6 position setup issue?
