I have the latest ArduPilot board /EM406 GPS in a RC car, v1.0 software, RTL set to 1, code uploaded successfully, 'OUT2' to steering servo, 'IN2' from Rx Steering channel, GPS lock on, MUX LED illuminates to indicate the autopilot is switching correctly, etc
I control the car to some distance (200ft or so) from me ('home') and flick the switch and then the car turns to the left and keeps on doing so in a never-ending circle? With RTL set to 0 it does the same seemingly ignoring the waypoints?
Anything I'm overlooking or suggestions as to what might be wrong? Is there an easier way to quickly test that the navigation function is working?
BTW, should the altitude be set to 0 on a ground vehicle or should it be ignored?
