"I haven't bought the apm 2.5+ board yet, because I was afraid that it won't work well with the epp fpv. ;) Maybe I'll order it within the next days. Hopefully the navigation is working well because I live in an alpine area and a navigation failure…"
I saw that you built an hobbyking epp fpv uav plane. I'd like to equip my epp fpv with an apm2.5, but I have some worries about the config file. Did you have been able to get a working param file? Is your epp uav working well?
