"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
H.O. CONTROLLER MODELS
DD500 - H.O. Pro Controller. New low cost controller features 15 band fixed resistor design like the DD515 and DD520 models. Brake and sensitivity rheostats (no coast), 14 gauge main wires and super small heat sink (1” x 1.25” x 3/4”) for light weight. Comes factory wired for positive polarity (can be changed by reversing two wires soldered to the transistor). Controls all Fray, Stock, Modified and R/O type motors. $179
DD550 - Power Transistor. Replacement power transistor. $11
DD551 - Brake/Coast Switch. Replacement switch used to select brake or coast feature. $8
DD552 - Brake Coast Pot. Replacement pot used to adjust brakes or coast power. $12
H.O. HD30 CONTROLLERS
DD521-HD30: The same overall construction as our current controllers. 100 ohm brake rheostat. Comes standard with a 290 ohm resistor network. Brake/coast switch and dual polarity. $258
DD531-HD30: All the features of the DD521 with our adjustable choke rheostat installed. $288
H.O. HD30 UPGRADE PCB
DD554: HD30 Upgrade PCB: (This upgrade kit is for any model with a choke) Convert your DD520 or DD530 10 or 15 band Pro Plus or Fanatic H.O. controller to our new 30 band high definition design. You get the HD30 circuit board with a standard 290 ohm resistor network board installed. Simply unsolder a few wires and remove the old PCB. Transfer the original brake and sensitivity rheostats over to the new HD30 board. Now bolt the PCB to the frame and solder a few wires to their correct positions. Simple instructions included. $56
DD555: Fanatic Upgrade Pots. Kit includes 15) 20 ohm Fanatic pots to convert your 15 band Pro Plus controller to a Fanatic model. Adjustable pots allow you to tune each band for total control of your band sensitivity. Unsolder and remove the individual resistors and solder the new Fanatic pots in place. $22
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.
