DD 304 controller                       New all in the handle Neo controller                Optional painted handles                       


MORE BREAKING NEWS! Neo controllers now feature our all in the handle design. The new layout has a thin heatsink mounted in the handle for a more user friendly design.




Computer designed and labeled circuit board. Wiper bands are nickel plated for durability.

Exclusive routed fiberglass frame is separate from the circuit board electronics. This allows for inexpensive upgrades in the future by simply replacing the circuit board.

Adjustable braking and sensitivity rheostats provide a wide adjustment range to match your car, track and driver characteristics for optimal racing performance.

“E”lectronic auto reset brake and power fuses with reverse diode protection for reliability.

High amp transistor design is virtually maintenance free.

Acu-Pivot trigger pin with trigger ball bearings are standard! Ball bearings keep the wiper button firmly in contact with the wiper bands with zero trigger side play even after years of racing.

New remote cable design on the HD30 takes the heatsink weight off the main wires. The heatsink/transistor assembly can be hung from the hook up studs.

All our designs can be serviced, repaired or upgraded by any racer. No returning to the factory, like other controllers! This is important if you want to avoid other manufacturers costly repair bills or if you are in another country.

All relay models feature a 40 amp relay and 12 ga wires.

Parma handles are standard on all Difalco controllers. They are more comfortable to hold than that square handle brand!

Genesis HD30 controllers feature a thin multi-conductor cable design and our fantastic E.S.P. brake relay for excellent full brake response.

Genesis HD30 controllers are positive polarity only. Please see the Neo or “E”motion controllers if you need dual polarity.

All controllers will work on 8 to 16 volts tracks.

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.

XLR Plug: Our 1/32 controllers are now available with an XLR plug (male). (plug is wired pin 1/black, pin 2/white, pin 3/red)

Ease of maintenance: Your Difalco controller will give you years of trouble free service with a minimum of maintenence. Clearly written instructions are included. The open frame design makes routine cleaning quick and easy.

Service and support: Complete troubleshooting instructions are included so in the unlikely event a problem should occur racers can quickly diagnose and fix most problems with readily available, inexpensive repair parts. If you ever need assistance, Jim at Difalco Design will be there with his 45 years of slot racing knowledge for advice or to service your controller.





Neo controllers blow all similarly priced controllers out of the water! Packed with features only found on more expensive controllers. Neo controllers feature dual polarity as standard and will work on 2 or 3 wire hookup tracks. Extra long and very flexible 14 ga wires for the best performance. Our ball bearing trigger provides silky smooth trigger action. Wide range sensitivity and brake rheostats with an optional traction control feature.

Genesis HD30 controllers feature a thin multi-conductor cable with our innovative E.S.P. (Extreme Stopping Power)  brake relay. The relay is located on the heatsink/transistor assembly just 1’ from the hook-up studs for reduced brake circuit resistance. The relay is activated by a tiny slide switch on the main circuit board and bypasses both the brake rheostat and the brake fuse for the lowest resistance possible. The E.S.P. has diode protection to prevent it from turning on in case of incorrect hook up. The E.S.P. relay is activated by the wiper board even before the trigger reaches the normal brake post. This turns on the relay earlier for better braking response. A full power relay with flexible 12 ga. wire to get all the power to the track. Genesis controllers also feature our exclusive plug in network circuit board that changes the band response to tune the controller to best match your motors R.P.M. and driving style!
