ROLL AND COMPASS ERROR Crius AIOP v2

[AKA Biggles]

Hi guys,
I';m pretty sure this has been seen before, but it';s new to me.
Just rebuilt the DJI clone hex with new frame top and bottom deck. Reconfigured it to X instead of +. After following the excellent guides by Jumpy and Gaza  I finally had it hovering fairly well indoors. It was a bit twitchy and over-responsive for me, so into the PIDs I dived. I made some changes based on the advice from the top blokes. OK I must have done something stoooopid, ';cos now the level is 22 deg out, and the hex wanted to roll severely to the right. I know there is an issue with the level calibrate button in Mission planner, so I went through the back door via terminal/setup/level. I have also reset the fc board (as far as I know - reset button on the PCB?), followed by deleting and reinstalling crius/arduine/megapirate completely. The final chapter tonight is that the only way I can fly it is to go through the terminal/setup/level routine with the hex held at a 22 deg roll to the left. Mission planner then shows the hex having a 22 deg right roll when sitting on the floor. It ain';t right, and I';m a bit lost .......... anyone have a clue?
PS the compass is about 30 deg out, too.
