Successful APM2 Failsafe Test


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!!!

  • Guys, please don't do that with your motor, running with one wire unplugged. That usually smokes the motor if a wire comes disconnected.

  • Con Grads on the test I am new at this and I learn from ever one of your videos! Who would of thought a battery would fail in a TX ?Have a good Day!

  • I'm using Transmetic 2200mah 11.1v lipo battery for FS-TH9X - it was added to my 9x when I bought it from LeaderHobby few months ago. Because of my fault I ran 9x when battery had aprox. 7.5V so it "poofed" a bit and I had to do some trick to convince Accucell to charge it but it works fine till now.

  • Thanks Mark, as soon as they are back in stock I will order a LIFE battery for my 9x! Trent I hope you don't take my comments wrong, I have watched every video you have done and enjoyed them.It's not that I haven't enjoyed your plane making videos but I enjoy the APM testing videos more.

    Try a LiFe battery in the 9x, you won't regret it.  Here's my notes on doing so:

    Here's how I replaced the battery pack on my Turnigy 9X radio.  Andreas did it first... I just copied what he did. It's pretty simple: c...
  • Oh! Sorry... I read it wrong... Thanks!

  • No I meant that I was enjoying that you are testing it again. I haven't done that test yet but and enjoyed the video! Keep up the good work!

  • @Jason: Would you not consider this testing the APM?

  • I'm enjoying seeing your videos get back to testing the APM! I
