Recently purchased original Pixhawk from 3DR . I have connected it to a Kyosho Axxe RC Car with 6 Ch 2.4 Mhz radio. In MANUAL Mode it runs really well . Compass, Gyro,is calibrated. The EKF is disabled. After collecting a few way points in MANUAL mode on a long open road by toggling CH7 on radio and then changing to AUTO mode, the car traces the way points perfectly the first time. But when I try to run the car again on the same way points , after maybe a couple of times of successful run , the car tends to "drift" in a unusual path .I think it not trying to go to home position because I am always starting in auto mode with HOME within a few meters right ahead of me. The way points stored show up perfectly on the MP Flight Planner page. It gives the impression that the coordinates of the drive way has changed. Is it possible that the GPS location of a particular spot can change within minutes ? What could be the issue ? We have tried tuning the steering but it is not solving the problem. Your help will be most appreciated as we need to complete this project .
