This week on MyGeekShow we tested the APM2's failsafe protocol. We approached this very carefully as a failure of the failsafe could result in damage or loss of the aircraft. We first ground tested the APM2 at various stages to determine when the APM2 would control the aircraft, as well how it responded to loss of control signal.
After determining the APM2 took control as predicted, we took the Shrike to the sky and put it to the real test; we turned off our transmitter. It performed perfectly! It loitered for a moment, and then returned to launch.
After its successful test, we flew around via FPV for fun, when all of a sudden... OUR TRANSMITTER DIED! It ran out of batteries! We DID NOT do this on purpose. Luckily, we had some extra batteries with us and switched them out in time to recover the airplane. Crazy.
The APM really saved our airplane that day. Thank you DIY-Drones!!!
