I was casting my eye over the range of Truspeed analogue controllers the other day, and it got me wondering about something...I can see that the top of the range MT II and the PWM II controllers have all the bells and whistles a race driver could ever need, but it was the other two lower spec controllers that puzzled me.

The BP II Transistor controller and the  MT I Mosfet/Transistor controller have the same two external sensitivity/brake adjusters, so what difference does the internal electronic architecture make in terms of user perception/car control?
