You hit the check mark in arduino and it does a verify by compiling it in a temp folder. That's the hex you want to install in Mission Planner. I get warnings when I compile 2.91b for a quad frame - seems related to heli code that is compiled out.

Dont run the makefile. Load the Arducopter.pde and compile it

I just tried again but the same results. The mega2560 is selected already.

Comment by Bo Barry on June 22, 2013 at 4:57pm

I didn't run the makefile, I loaded up the Arducopter.pde sketch in Arduino, selected the mega2560 under Tools, and it compiled perfectly (slowly).

Still building on mine so the software hasn't been loaded.

Good luck, Bo

Yes, I downloaded the modified Arduino tools. I downloaded the source from the GIT. I ran the makefile. I set the file path and board type.

There are still a lot of warnings and I the only HEX file I can find is in the temp folder.

I am looking for a form thread or something to help sort it out.

Normally, you should not have any warning with the Arducopter code. Do you use the modified Arduino version for ArduCopter? In the first comment lines, there is a link to download the modifed Arduino version.

I am trying to compile the source and need some assistance. Anyone know where I can find some assistance? I can compile but there are a lot of warnings and I am not sure about the output file.

Can APM 2.5 fly a standart hexacopter with one engine failure? I mean, if it has enough power?

Colin, you might want to post your question in the discussion section. It is better suited for Q&A. Just click on the 'Add a Discsusion' above or go to Forum and drill down to the appropriate section.

Hi All I am having a problems taming the throttle on my hex. I'm new to the hobby so bare with me on this but while on the ground tuning if i up the throttle about a third and stop the motors continue to accelerate on there own quite a bit more in a slow build. Dropping the throttle does not immediately slow them until i,m down at 0 throttle. As you can imagine testing in flight has given me some real grief! Any ideas would be most welcome. Is the problem with the ESC's or the APM settings?
