I posted on here some time ago saying that my APM 2.5 wouldn't arm my ESCs (red light continues to blink). At the time i was using DJI Opto ESCs and I kind of put the problem down to them. So i recently purchased some nice new HobbyKing ESCs with SimonK firmware. Finally found the time to install them, and to cut a long story short .... still nothing but i blinking red light.
I'm using the latest Mission Planner (1.2.61), latest Arducopter firmware (3.0.1). Have made sure everything is calibrated (it tells me that the calibration is successful), made sure my DX8 radio is calibrated properly and that no channels are mixed up - low throttle position reading 900 on the calibration page. Yet if i try to arm, with or without it plugged into the laptop via USB, it won't arm!
Yes i've read all the guides and Googled the hell out of it, but regardless of what i try it just won't play ball.
Is there a chance the board is faulty? I'm 99% certain i'm not doing anything wrong. I've been over everything at least 10 times to make sure it's not me.
