thanks a lot ADI for the reply. about the motor timing well thats what I thought it should be but had no clear idea of how to do it. AW i have a little problem with the motors currently. I've been testing the vehicle quite a lot and now the four motors are showing very different perfomances. for a perticular PWM value the four motors have different rpm values. Is this the same with your motors? Do you think that this is because of the different timing on different motors? and (tooo many questions im afraid , sorry...) apart from the timing adjustment do you use any kind of hardware or firmware adjusments to make the motors performe the same for a given PWM?


Many thanks in advance
