Ds Slot Racing Controller
Traction control feature:Adjustable rheostat shifts the sensitivity range and reduces the power on the last band of the controller. This optional feature limits the power available on the last bands of the controller to reduce the chance of overpowering the car and sliding out at the end of a turn. Controllers and “ohm” lesson needed - posted in HO Racing: Hey everyone, I am fairly new to this obsession of slot car madness and need a lesson on controllers, to be more specific: What is the difference in controller ohms and how do the different ohm controllers affect the car, for example, 60, 90, 120. Controller Impedance: Commercial after-market slot car hand controllers come in a variety of resistor sizes. Hand controllers built specifically for HO Slot Car Racing are normally rated at 60, 45 and 25 ohms of electrical resistance, or impedance to current flow. Manufacturer of electrical appliances and electronic slot tracks. Manufacturer of lap, controllers, cables, feeders, controls for almost all market-compatible slot tracks.
'E'MOTION H.O. CONTROLLERS
Difalco Design, the number one name in custom 1/24th slot car controllers, is coming to H.O. racing. Our controllers have won over 80% of all classes held at the 1/24th USRA Div. 1 Nationals the last 8 years. Our line of 1/24th “E”Motion electronic transistor controllers have quickly become known for their innovative features, reliability and ease of maintenance.

STANDARD H.O. CONTROLLER FEATURES
Computer designed and labeled circuit board. Wiper bands are nickel plated for durability and will not tarnish.
Fifteen wiper band contacts instead of eight for smoother power application and more control than eight band designs.
Exclusive computer routed fiberglass frame. Will not cause shorts and keeps wiring neat.
Electronic transistor design has a wide range sensitivity pot to control all types of H.O. cars. No wiper band arcing.
Heavy duty 10 gauge silicone wire and floating silver power contact. Lower voltage drop than 14 gauge wire for more power to your car.
New Acu-Pivot Trigger Pin reduces bushing play to a minimum and keeps that new controller feel.
Circuit protection. Resetable fuse on brake circuit automatically starts working after hook up is corrected. Reverse polarity diode protects transistor from damage.
Incredibly simple design. No hidden components! Our controllers can be repaired by any racer! Complete instructions describing features, maintenance and troubleshooting included.
Dual polarity - simple, tamper resistant plug system switches between positive and negative polarity tracks.
Brake/Off/Coast switch with full range brake/electronic coast pot. Electronic coast uses the transistor to power the car instead of a rheostat which can burn out more easily.
No brake post required! Unlike other transistor controllers you don't need a brake connection to make this controller work! Electronic coast feature still functions also.
OPTIONAL FEATURES
Electronic Choke. Simply turn down the separate choke pot to reduce track power to the car when needed. Makes fast cars more drivable on tight twisty tracks and boosts your race lap totals.
“Fanatic” feature. This feature sets Difalco Design controllers apart from everybody else! An individual adjustment pot on each band is used to instantly change the controllers power curve for the ultimate control! With the turn of a small screwdriver you can make each band more or less sensitive. Tune any car to any track or driving style!

H.O. HD30 RESISTOR NETWORKS
Miniature plug in circuit board allows racer to change the overall band resistance to best suit the type of motor being used. The higher the listed ohms the slower the band response and the lower the listed ohms the faster the band response. The standard networks are soldered and ready to install and have the same value resistance per band. The custom networks have miniature sockets and various values of resistors that can be mixed and matched to get the desired band response. All H.O. and 1/32 controllers come standard with a 290 ohm network. As a comparison, our 15 band Fanatic controllers have 300 ohms of total resistance.
Note: the network resistance, 290 ohms for example, is the resistance needed to control our transistor circuit and should not be confused with the ohms rating on a typical Parma type resistor.
