Thanks Randall. I'll hopefully get out later in the week and test different firm wares in the field. I managed to tape all of my plugs together so that each group of plugs can be removed individually, which should stop the issue of removing all plugs to flash firmware easier, as my board is hidden in the middle of my frame and a pain to get to if you need to remove plugs.
I have been reading on that evil website that it seems I am not the only one who has a strange issue with the Rabbit causing the motors to not accelerate correctly then suddenly come alive and flip to a crash. I would say the new firmware has an issue.
What FW are you currently running?
