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.

 

Acu-Pivot threaded trigger pin with 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.

 

Floating wiper button with rounded face for reduced friction and perfect contact.

 

Flexible copper trigger braid will last for years of racing.

 

Extra long cable allows even tall racers to stand further from the drivers station for the best view of the track.

 

Parma handles are standard on all Difalco controllers. Our frame is screwed to the rear handle to keep the controller from flexing inside the handle.

 

Stainless steel hardware will not corrode and will look like new years from now.

 

Copper alligator clips with color coded insulators.

 

 

 

 

 

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

 

17 band or 30 band designs provide a very wide sensitivity range for all H.O. cars.

 

Optional 30 band plug and play resistor network can be used to slow down or speed up the overall sensitivity range. Our custom curved response networks feature 3 different resistor values that plug into miniature sockets on the network circuit board. This allows you to have a custom power curve to match your driving style.

 

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.

 

100 ohm brake rheostat on the DD500, DD501, DD502, DD506, and DD507.

 

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

 

High amp transistor design is virtually maintenance free.

 

Standard dual polarity feature works on both positive and negative wired tracks.
