Sounds like the first time I tried to start up a KK board. Remove your props if you haven't already. Set your endpoints to 125% and make sure your dual rates (especially yaw since that's what arms it) are at least 100%. Turn on your TX and try to arm the board. If it doesn't arm, unplug it, reverse your throttle channel, power it up and try to arm it again. Once you get it to arm then you can play with reducing EPA and dual rates, if it quits arming then set them back up again. I originally had mine set up with 100% EPA and 70% dual rates on yaw and it would not arm. It was frustrating trying to figure out what was wrong.
