Thanks Don and Martin.
I'll have a look at the settings Don. It's a very good point about the moment of inertia. In a skype call yesterday, Lucas referred to a C14 as 'big' and that should've prompted me to ask about the acceleration values, but I was too engrossed in trying to start some small hex head bolts into the motor housing....:)
I'llprobably check with lucas as well to see if he has any mount specific thoughts on it.
I'll report back.
thanks for help,
