Hi got my copter flying sort of ok then tried to improve the controls in CC3D  but now it will not arm so how do i wipe off all my imputes so i can start afresh

If you connect the board into Librepilot you can in the "input" page arm settings select what you want. "Yaw right" is the most commonly used option.

Not sure why you want to erase things?

Post your config file.
File > Export UAV Settings...

Like Jeuke36 says, the arm issue can be a Arming setting not set or just alarm about flightmodes or other stuff.
