I am still using Erle Brain 2 and I want to try out the latest version of ArduCopter.
Now, previously I was used to downloading the ArduCopter.elf file and simply replacing it into the relevant directory and then running it.
However, now, I have noticed that the file is simply called ArduCopter: http://firmware.eu.ardupilot.org/Copter/latest/erlebrain2/
So, does this file need to be compiled?
Is there an online site which I could visit which has pre-compiled ArduCopter.elf files?
