what frsky receiver for pixhawk?

Posted by Hugues on January 22, 2014 at 3:50pm

Hi,

I am building a quad with a pixhawk fc. Pixhawk does not support normal PWM receiver inputs. Therefore I need to get a PPMsum compatible FrSky receiver.

The last X8R frsky receiver does not support PPMsum.

So my question: which frsky 8 ch receiver having CPPM (PPMSum) can I use ?

Thx

Thx all, i confirm it works connecting X8R Sbus port to Pixhawk RC in.

The problem is the "Quick Start Guide" which comes with the PixHawk clearly shows you should connect the S.BUS receiver to the SB connection. This is wrong. As stated above, it needs to be connected to the RC port. It works fine there for me.

I have the D8R-II Plus flashed with new firmware outputting cppm. If you want a nice small light reciever the 4 channel ones are the way to go. With the cppm firmware they output 8 channels.
