Professor Motor Electronic Controller
PMTR2110
Intended application : HO, 1/32 home & club track racing & 1/24 commercial track racing through 16D and JK
Falcon. Not recommended for Group 12 / Group 15 or high-powered glue racing
This model features the following high quality features
· Recommended operating voltage range 10 to 15 volts DC
· Wired for POSITIVE polarity tracks (not for direct connection to home set power base)
· Variable Braking System (high quality wire wound pot to vary brake performance)
· Variable Sensitivity System (high quality single wire wound pot to adjust sensitivity setting)
· Electronic “Platinum Series” transistor design with wide range of control
· Fault tolerant ultra robust circuit design to protect against overload or short circuit damage
· Internal handle-protected aluminum heat sink
· Fully functional in 2 wire (non-brake) application (some HO & 1/32)
· Power pilot light system for power and polarity indication
· Extra long, heavy duty 13 gage super flexible, high temp silicone controller leads
· Solid copper alligator clips with color coded vinyl insulating boots
· High impact polycarbonate plastic molded handle, stainless steel hardware throughout
· Low friction silver alloy wiper button with ultra hard nickel plated contact surface
Use & Care Instructions
· Brake Adjust – Adjust the red color-coded knob with the white line “up” for MAXIMUM braking effect. Turn
that knob counter-clockwise to reduce braking effect. With 1/24 commercial racing cars on large routed
tracks only a small portion of the brake range will be used.
· Sensitivity Adjust - Adjust the silver color-coded knob with the white line “up” for MINIMUM sensitivity. Turn
that knob counter-clockwise to increase the sensitivity (provide more power to the car on initial application of
the throttle).
· Caution ! : Regular maintenance is required to keep the controller contacts clean and free from foreign
objects & debris. Failure to properly clean, lube and maintain the contacts will cause the controller to fail, will
allow the car to be driven without the throttle being depressed and can result in the wire wound pot used for
brake control becoming short circuited & damaged. Please take this warning seriously and follow this
process to keep the contacts clean & properly lubricated :
1. Remove the front half of the controller case by loosening the three bolts
2. Clean all debris from the nickel-plated contacts with a Q-Tip and lighter fluid
3. The sliding contacts MUST be CAREFULLY lubricated to reduce contact wear and provide a
smoother controller action. To lube, do so as follows :
a. Place a SMALL amount of Super Lube PTFE lube on the end of a Q-Tip & apply to the
nickel contacts in the area where the silver alloy contact travels
b. Cycle the trigger a few times
c. Use a Q-Tip with lighter fluid to remove any excess lube outside of the area where the
contacts meet (remove 90% of the lube you just applied)
d. Examine the contact area to insure that cotton fibers from the Q-Tip are removed and
that residual lube is minimal & barely visible
4. Repeat this cleaning / lube process on a frequent basis (every 1-2 weeks) for best results.
· Periodic Maintenance – lube the trigger pivot bushing with plastic compatible oil
Optional Upgrade
· Power Relay System PMTR2037 – provides a more positive low resistance path at Wide Open Throttle
· PMTR2039 5 Ohm Brake Pot if using exclusively for 1/24 commercial track racing
Special Note :
Professor Motor now specifies "Super Lube" as the preferred PTFE fortified lubricant for the rubbing contacts of the Platinum Series controllers.
This lube is far superior to the previously recommended Tri-Flo lube. Super Lube is available in 2 size containers.
please see the Liquids Catalog for more information and follow the NEW instructions for the required maintenance.
