3PK issue with spekky module

[Theshiro]

chaps. using an RC18T last night suddenly had the wheels turn inwards to the right and the throttle not being at neutral, as though the settings had jumped from 50/50 to 70/30...I was running the car at the time and did not think this was an adjustment I could accidently make. tried rebinding and even a new model but no change

Trying on a different car this morning and the same thing has happened. I have an old module so I swapped and rebound and hey presto it works....is the module knacked, or is there something glaryingly obvious that I have missed?
