So our plane crashed while flight testing the APM 1.0. The aircraft simply stopped responding to pilot control as if the entire board shut off. We were not using any autopilot modes but was in manual. We recovered the autopilot as it was completely i
Read more…Our plane just went down today. The pilot was in manual mode and I was monitoring the telemetry on the GCS laptop. All of a sudden Mission Planner freezes and the pilot goes "I have no control!" The plane goes down and we have no idea what happened.

I'd like to grab telemetry data from the APM and/or X-Plane to MATLAB.

Right now i'm exporting the telemetry data into the log file and looking at it through Excel. Is there a easier way to isolate variables I need? I've seen from old screenshots that there was a GUI in Mission Planner that makes it easier to view the t

I have a good proportional gain for the elevator servo, so it maintains good pitch attitude during Stabilize mode. However, with the pilot's hand

If the plane is made with carbon fiber shielding or other GPS signal blo

We've been trying to prep and fly 3 pairs of Xbees on 3 rc planes for the past week. We've had repeated issues with the Xbees all the time. Sometimes it would connect and work great. On other days it would disconnect. No issues with the boards as we

I have to reverse the rudder and elevator on my Futaba radio to get the correct direction on the surfaces. It would appear this reference is independent from Mavlink and

If it goes through the 900Mhz xbee what happens when the link is broken or the autopilot loses power for any reason?

My question is if i solder on the magnetometer for the APM and used it on a airplane instead of a quad rotor, how do I know it works or if it does anything?
The only thing in the Mission Planner is "Enable Magnetometer." Yet there is nothing that tel
