I read on KoPropos site that the digitals, at least theirs, have a tendancy to blow the boards in them when or if they get bound up and you are trying to steer at the same time. Say if you hit a board fairly hard and it puts stress on the servo because it is receiving a signal to steer at the same time. How likely is this to happen and do most Digitals have this problem or is it something that has been worked out?
