If you really have to own a resistor controller , the DS is OK. (I used DS controllers for 2 or 3 years)
I grew to hate resistor controllers for club racing because:
- different controllers with different ohm rating are needed to make the feel of the car right when different motors are used. I Found that 15, 25 and 35 were the minimum required for the cars I use at club racing. DS don't make a 15 ohm so I ended up using an old (borrowed) vintage RussKit controller for some classes.
- the wiper arm and controller's wiper track need regular cleaning to keep them working properly.
- the physical contact of the wiper arm depends on the tension of the wiper arm itself and is different between every controller. That tension gives every controller a different feel. Changing to a backup controller during a race night will always impact results because it takes 1 race to adapt to the feel of the backup controller.
- when the physical contacts start to fail, car control becomes erratic, more often than not, in mid race.
- resistor controllers are linear. There are some characteristics of motors that can not be adjusted with a simple linear rheostat controller.
In summary PWM controllers offer reliability, consistency and adaptability (to different motors, voltages and tracks)
PWM controllers are also good value for money because you only need one. Mine covers all of my analogue and digital club racing needs.
Slot car racing is a COOL-RETRO hobby.
Resistor controllers are not cool, Just OLD
