I received my Erle-Rover a few months ago and just got around to assembling it and testing it out. I fully charged the battery and plugged in all the peripherals in their respective spots. However, while using the RC controller (B2-STX Pro) steering works perfectly fine, but the throttle does not. I searched online for a solution and loaded up APMPlanner and uploaded the updated parameters file and updated the parameters with the new ones. This did not solve my issue. In APM planner I can see the RC getting throttle input from the controller when I use the RC controller trigger. I can provide pictures or videos if needed.
