2 things I can think of happened since it was flying fine. 1 it fell over in the back of the van so could have knocked something, 2 I changed the modes around on the controller after reading up on them, which involved me trying to work out if I could use extra buttons on the control for selecting more modes and I may have disabled one of the twiddly nobs to use one of the switches, can't remember.
When I first tried to fly after that it wouldn't arm due to ACRO_BAL_ROLL/PITCH so I tweaked an acro roll sort of setting to get through that.. I've since put that setting back which just means the copter wont arm at all.
I did double check connections as one motor seemed a a bit hit or miss and would stop on occasion and it turns out the connections was barely hanging by a thread so I resoldered that and the motor is now perfect.
If I do force it through the pre arm checks then the quadcopter will respond to throttle only and go up or down but any kind of control input other than that doesn't seem to have any effect. I have gone into radio calibrate and all stick inputs seems to be getting to the quadcopter.
Any ideas!?
I've tried searching Google but I'm not really coming up with anything useful.

Looking at the graph for roll it bares no resemblance to what is desired. Similar for pitch... yaw however doesn't look bad although I don't recall trying to adjust yaw control.
