Hey guys, I'm new to LibrePilot, but have over 50 years flying RC.  I just set up my CC3D board and all went OK but, the motors won't arm. 
IE: plug in on level surface, wait @ 30 seconds while blue light flash rapidly, try to arm, blue light changes to slow flash.  Try to throttle up, but, nothing happens.
Please help!

After doing the setup did you change it from always disarmed to whatever arming pattern you wanted?  Setup disables arming for safety reasons and requires you to change to whatever arming pattern you want.

configuration -> input tab -> arming settings sub-tab

Thank you soooo much hwh, that was it!  I surely missed that one step.

You're welcome. 

It's easy to miss a step like that, especially the first time you do it.
