For those of you that have successfully used the ArduPilot in an RC truck or car, have you used the basic ArduPilot 1.0 code and, if so, was it heavily modified from the code used to control airplanes? I'm just getting started on controlling my crawler with ArduPilot and I need some suggestions from those of you that have done this on how to get started. First off, how would one modify the code to make the maximum speed of the ESC very slow? I want to try playing around with the navigation settings, but I want to be able to walk along side the car as it's navigating. Thanks for any suggestions that you might have.
In the mean time, I have been experimenting with simply connecting a dummy servo to Ardupilot OUT 1 and manually controlling the throttle, but have had some difficulty obtaining a GPS lock. The MUX and POWER lights are on, and the LED on the GPS module itself is on, but the GPS LOCK light remains off and the STAT light just turns off after waiting for a while. What is the normal amount of time to wait for a GPS lock?
