DX7 W/ Pixhawk, APM 2.8 and Trad Heli
I will be trying to return to the heli world after a few year break, wanting to work on a drone/autonomous project and can use some help.
The issue is that I will be wanting to use a conventional heli with a DX7 and going on the cheap, using a Pixhawk or APM 2.8 flight controller. I call it an issue because from what I can tell I need an 8 channel controller to make this happen. seems I need channel 8 for the throttle and some short of dial on the transmitter...both of which rule out the Dx7 So, the question is, can I make the chosen controller work with the DX7....the bird will be an electric old style trex 600. Basically I'm trying to make due with what I have instead of selling off stuff and buying a new tx and "drone" type bird. Eventually I'll go the multi-rotor path but for now I simply don't have the funds any direction would be helpful.

I was able to reprogram my DX7 to work and fly my FW550 using a Naza setup. But I can't help you out here with your Pixhawk or APM flight controller.
Hope you find a solution!

The APM2’s input channel mapping is: Channel 1: Aileron (aka Roll) Channel 2: Elevator (aka Pitch) Channel 3: Collective Pitch Channel 4: Rudder (aka Yaw) Channel 5: Flight Mode Channel 6: In-flight tuning knob Channel 7: Aux function switch (i.e. Camera trigger, Sonar on/off) Channel 8: Main rotor speed You could swap CH8 for 7 and you have all you need. Just loose a some camera function. |

Flynhawn- How did you reprogram the DX7? I'm not aware of any place to connect to a computer...Did you make a custom interface cable/plug?
I never tried to get the DX7 to work with the APM...I ended up just ordering a Taranis 9D+ Given the difficulty and time available, still haven't messed with the project.

Had to use some switch-hack to make it work, but I'm getting a new radio for cams and other stuff now. |
