  Ηι Mauro, 

  You need to download the modified arduino version from downloads here , our code is huge for regular arduino compared to other projects

  happy compiling

  i think, arduino 1.0+ does not recognizes *.pde file type. you will have to change the file type extension of *.pde. But pls cross chk with someone who is regularly using arduino for compiling. i do not use arduino for loading arduplane. i use mission planner for laoding the code to APM.

  I downloaded the latest version of arduino 1.0.3 to load my custom firmware on my APM 2.0.

  But i cannot compile not even the original arduplane 2.68 code ?

  Looks like arduino purposely exclude the core libraries creating a lot of errors.

  Do you guys have any clue?

  Thanks

  Neil, on the FrSky modules I have in my JR 9X II, you program the failsafe to hold pre defined outputs.

  Mine is prgrammed to to set the APM1 to auto, and complete the mission.

  And yes it is beyond cool to take off, get some altitude, and switch the TX off !

  Priceless to watch the faces of the uninformed at our club when I put the TX down, walk to the car and grab a beer :-)

  Fair enough, I'l do some research and figure it out. 

  The RTL and circle at the flick of a switch is cool to watch. Too much fun!

  Thanks Chris

  Neil: Every RC receiver does something different when it loses signal. Some generate PWM = 0. Others hold the last PWM. Others have a built-in failsafe function where all channels generate last PWM but throttle, which generates PWM =  0. Others let you pre-program what happens.  Etc, etc...

  I have no idea what an Orange Spectrum-compatible RX does. Perhaps it's one of the above, perhaps it's yet something else. You'll just have to read the instruction manual, if it comes with one, to know. Sorry that it's confusing, but I'm afraid that's just the state of the RC industry -- no standardization at all.

  Chris, thanks for the reply. The setup instructions say the receiver needs to "generate a predictable signal-loss behavior". Whats that? I'm using a Spektrum DX7 with Orange 6 ch receivers now in my plane and before in my Rover but I'm considering switching to a Turnigy 9 channel radio. And if I read this correctly if the receiver/APM does not have a signal for 1.5 seconds the APM goes into circle mode and after 20 seconds it goes into RTL. I don't understand why there needs to be all the setup to get this feature to work. If the signal is lost, the receiver is getting nothing from the radio and if the receiver/APM is not getting a signal from the radio the APM should go into RTL. Too simple I suppose?

  I want the Failsafe RTL to always be in the background no matter what else I do with the APM. Everything else is gravy.

  Failsafe RTL is the most important feature of the APM, especially when in AUTO mode.

  Thanks again,

  Neil

  Neil: Yes, that's exactly what a RTL failsafe is for. But you need to set it up properly for you RC system, since they're all different (the Mission Planner will walk you through that).

  On 9-22-12   Locko asked a very good question that was not answered regarding the Failsafe RTL.

  I have a APM 2.5 and I would also like something clarified. I need a RTL if the receiver loses contact with the radio such as when the plane flies "too far away".

   The instructions for Failsafe  say;

  "Here's what the failsafe will not do:

  1.

  2.Detect if you're flying too far away or .....

  Isn't that a reasonable use for a Failsafe RTL? To return your plane if you fly out of range?

  Thanks

  CAN ANYONE tell me HOW TO DO Quaternion implementation in APM - 1. Can somebody PLEASE give me a hint on how to use it? I am stuck."

  Thanks!
