Cube Orange: Help me fit all the cables on the rails

Hello.

I’m currently building a tramendous (0,43m^2 wing area) fixed wing drone. And so i need one servo for every movable surface; Rudder, 2x elevators, 2x spoilerons and 2x flaps. My plane is using the Pilot Cube Orange+ flight controller. My problem is, that i somehow need to fit all these 7 servo cables into the rails, alongside 2x BEC from the ESCs. I know that there is only 8 I/O rails on the cube, and i have 9 devices. Can someone help me find out how i fit all the cables onto the rails?

First i want to ask, if it is possible to put any of the cables into the FMU rails? This seems very tempting, but from what i have read it is not possible.

Is my only other option then to combine the outputs for the elevators so that i only have 7 plugs to put on the rails?

I would also like to note, that i don’t use the RCIN pins, as i use a RFDx radio modem connected to the cubes TELEM port. Can i somehow use those pins?

Thanks for your time.

Use the Main outputs for the servo’s and 2 Aux outputs for the motors. What’s the problem?

Thanks, i just read in some places that the BEC could not go into the AUX. One of the reasons i could find was that the BEC could be 5V and that would not work with the rails 3.3V setup.

This probably won’t exactly match your configuration but you get the idea:

Thank you very much. Have a nice rest of your day!

You don’t need for each servo an own control channel from the FC. You only need for each independent function a seperate channel. So for example the 2 elevator servos can just be connected via a Y-cable together to only one port. Maybe the same for the 2 flaps servos

Good point. Although on some Planes I have put them on separate channels anyway for future options.
