I am trying to put a Pixhawk 1 flight controller in an electric RC glider. I am using a FlySky FS-i6x radio system with the PPM port (channel one, usually used for the ailerons) on the receiver cabled to the RC IN port on the Pixhawk. I am finding that I am not getting a signal sent to the throttle channel, but I am getting signal sent to the other flight controls. I would like to converse with someone who has experience with such a system. Thanks!
