Problem 1:The APM .log files contain CAM messages based on when the autopilot commanded the camera to be triggered. It doesn't know when or if the camera actually triggered. This can result in CAM…Continue

Today's autolanding attempt with my Skywalker 1880 was a failure. I attempted to insert some Do_Change_Speed commands to incrementally slow down from cruise speed to landing speed. On the base…Continue

"Ay is what I use when graphing in real time using the Tuning window in MP.
I’m not near a computer so I can’t tell you what to look for in the logs. Both logs should have accelerometer data. You are looking for lateral (side to…"
"How do you know that you don’t need rudder? The plane will fly in a straight line of the ailerons are compensating for the rudder. Check the lateral acceleration in the logs to be sure. "
"I’ve seen this before, especially with the Skywalker. I suspect that your plane is flying in a slip due to the spiraling slipstream from the big pusher prop hitting the tail and creating a yaw. You can see the plane flying in a slip…"
