I have gone over "Teleoperation with MAVROS" in simulation tutorial. But I found out that the erle quadcopter doesn't response to yaw input from rqt "ros_erle_teleoperation". Not only from GUI teleoperation, it also happens with joytick. It seems like the erle corpter model has the error with Yaw simulation.
Even I tried in MAVProxy with SYSID_MYGCS 255, and in ALT_HOLD mode with command "rc 4 1800", the quadcorpter still doesn't turn around.
Anyone has ideas how to fix this issue, do I need to modify urdf file of erle model or modify/change plug-in in Gazebo? Thanks.
