Hi,

Does somebody may explain to me how works the breaking effect on Scalex? The controller has 3 wires, one for the +, one for the - , and one for the break; but the track is connected only to 2 wires the + and the -. I can't figure out how the breaking wire fit in that system? Does this wire add a kind of resistor effect to lower the voltage quicker when the trigger is released or something like that?
Thanks for your help.

Regards,
Maverick.

The brake wire puts a dead short across the motor and the back emf generated by the motor as it rolls inturn slows it down faster than if the motor was not shorted .It is posible to put an extra resistor in the brake line to reduce the brake effect to a level you require.There is a diagram on my web site

Thanks Graham! I had a look to your web site. I have a Professor Motor controller and I was thinking to add a variable breaking effect system. PM is selling one but first of all I am not sure to be able to find it easily in France and second of all it's too risky for me to upgrade myself my controller, this kit doesn't seems to be very easy to install for beginner in soldering! Do you think the following design could work to add a variable breaking effect without having modifying my controller?:
It would be based on a small box plugged between the controller and the Scalex power base. This box will have a female input jack where will be be plugged the controller and a output male jack plugged to the power base. The positive and negative wire will be directly connected between the female and male jack. A 50Ohm potentiometer will be soldered in serie with the break wire between the female and the male jack.

Cheers,
Maverick.
