wanna watch Bear Grylls doesn't come across it :P wish i could afford to travel around the world competing. need a robot first. progress is slow though. waiting on a custom controller, mainly down to the costs of off the shelf controllers. but im assured its more than half way there so shouldn't be too long. its all in CAD and ready to start. and a quick question while im at it. the Sabertooth Dual 5A Motor Controller, anyone know the frequency of the pulse width modulation? (sorry if that doesn't make sense, it isn't my question and i may have worded it wrong)
