I wanted to add a cc3d to my car (jlb cheetah), Plugged the esc and servo with no issue, x8r in sbus mode with no problem.
Started configuration and everything worked good.
But then I can't arm at all. Neither with stick position or radio stick. the only way is to put to always arm (but I obviously don't want that even if car are "less" dangerous than multirotor).
I precise (for those who did'nt guess with the x8r) that I use the taranis x9d (I don't like steering wheel radio).
Do you have an idea of my issue (I use 15.09 since the arch repo is not updated yet and I honestly don't want to build it)
