I have nice setup of APM1 (2560) with Arduplane 2.40 in large flying wing. Plane is grounded for about a year now and I want to fly it again. It worked well, everything was set up well. I am little afraid that upgrade to latest firmware will break my settings. Is it safe to upgrade, load old parameters and ready to go? Or fresh setup is mandatory?
I do not have compass module on my old APM, can I still use arduplane without it?
I have current sensor AC756-050B, which outputs: 2.5V=0A, 4.5V=50A (and 0.5V=-50A)
It was needed to dig into code to and program current sensor manually as there was no way to calibrate this sensor via MP. Still have to do this or can I load precompiled firmware and calibrate this in MP?
