Looking for suggestions on good motors that are a lot slower than the typical ones we use these days for my home track. No matter how much I gear down and/or lead weight up the cars, they are still too fast for most of the casual racers (friends/family/neighbors, etc.) that come over and want to make a few laps. I would prefer not to go the route of adding a voltage drop to my power supply and would prefer to just make up a few batches of cars, that are, well... slow!
 
Any suggestions? And I would like to use the standard stamped steel/flexi chassis that I have about two billion of instead of scratchbuilding for these cars.
 
Thanks,

Bob

Try adding a few diodes either in the lead wire / motor circuit or in the power wire of a "guest" controller.

 

Each diode drops the voltage .7 volts.

Try the JK Hawk 25 and Hawk MB motors. Someone posted here indicating the Hawk 25 is bog-slow; I think it is intended as a homeset motor but not sure. The Hawk MB is the faster of the two. (Note that the motor factory messed up JK's last order containing Hawk 25s and that motor may be hard to find for a few weeks while they do another run .)

If you need to go slower than that, I think you'll want to look at some of the motors sold into the 1/32 market. Butch Dunaway (Pappy here at Slotblog) would probably have some suggestions for you, as he has a home track as well and plays a bit with the 1/32 guys.

Never forget that first place goes to the racer with the MOST laps, not the racer with the FASTEST lap

Bob,

 

The Hawk 25 is a good choice for beginners on your track. You can play with gearing to get them slower or a bit quicker. A Retro Hawk on my track will run 3.8 seconds while the Hawk 25 is more like 5 or 5.2. They are in short supply for the next few weeks, but give them a try.

Another good motor is the H&R Hawk. Used by the local 1/24 hardbody club, it's a 18,000 RPM motor. H&R also sell a Jack Rabbit that's 14,000 RPM, but I haven't tried it.

Install one of these in the car.

2 Ohm 10W Resistor Wire Wound 5% Tolerance

If 2 ohm is too slow, go with 1.5 or 1 ohm.

Use 10 watts, minimum.

Also you might not want to have your guests drive the car continually for an 1 hour plus.

Turn down the voltage on the track. That will also make the motor last longer. Use diodes as suggested or a variable power supply.

In case you got confused, JK Products "HAWK" line includes various RPM output motors in the same FK 130 can,   15K;  25K;  Hawk-7;  Hawk Retro (latter both 50K+).

 

H & R Products market several FC-130 and FK-130 motors (all painted blue)  from 14K to over 40K RPM output with better pricing that similar Scalextric/Carrera/Ninco/Slot-it brands.  My homeset club use the 14K and 18K a lot as 'spec motors'...

 

Four diodes in series in the car or the controller (+) works great to drop about 3 volts for any car...and does not affect the braking action like the resistor can.
