Information on Controllers

Choosing your controller is pretty important, as it needs to give you confidence that you’ve got a good idea of how hard to squeeze the throttle and when to go rapidly without all hell breaking loose.

The most popular controllers at the club, and probably around the world, are made by Parma. Basic models come with 15, 25, 35 and 45 ohm resistors, there are also Parma Plus models with the same variety of resistors but slightly better quality and the capacity to open up a few more revs on the main straight.

The alternative to these individual controllers is a one-size-fits-all adjustable controller, of which the most popular is Truspeed, made by a local racer, Steve Hills. These operate rather differently to traditional resistors, with options for Pulse Width Modulation and Diode as well as the traditional Transistor.

It is important to note, however, that electronic controllers such as Slot It SCP will not work as they require the braking circuit to be permanently connected.

Some of our racers have built their own controllers as well. The possibilities are apparently limitless, including one that is a combination of a vintage Scalextric hand throttle and Doctor Who’s Sonic Screwdriver.

Whichever throttle you choose, it needs to be wired properly. The diagram for this process to suit our track can be found here:
