[OXO cube]

thanks guys
 
after more internet delving 
i think i understand that the ohm's affects the initial trigger input ( lower ohm = more power initially ?), since the max power is a constant 


and then letting go of the trigger in effect turns the motor into a dynamo therefore slowing the motor faster which in turn stops the driven wheels faster creating brakes 

are these the 2 knobs seen on some controllers that can be adjusted ?

is this correct ? or have i got it wrong again hehehe
