Hand controller replacement

usguys07 · 14th-Jul-23, 05:50 AM

Hi guys, I'm just getting back into slot cars after a long period away from the hobby.
I am building a wooden routed and braided track and want to know:
Q1. what lane spacing I need for 1:24 Flexi and wing cars using s16d and g20 motors.
Q2. I have my old Parma 2ohm controller which was a resistor unit but they don't seem to be available here in Australia any more. What can I replace them with?
Thanks, Tim

Google confirmed my initial thought that commercial slot car tracks are usually 4.5" between slots, though you can get by with 4" if you want to fit more lanes into a confined space.

There are lots of controller options out there, running the gamut of features and price. It would probably be best to start with a budget (per controller) before asking for recommendations, which can push a grand in some cases. Usually, a decent controller with the basic adjustments will be under $200.

You may also be able to post a "Want to buy" post for Parma 2ohm controllers. There's probably a good number out there collecting dust.

Shipping from the US might be expensive but I have a 2 ohm Turbo and an external resistor controller from my commercial track days. PM if interested.

Thanks chappyman66, yeah postage from the US is really expensive compared to a lot of other countries but thanks for the reply I'll keep you in mind if I am unsuccessful here in Australia.
Thanks again, Tim

MR Slotcar (in Hallam just south of Melbourne ) sell Difalco controllers, which over the last 30+ years have been the most popular controllers worldwide for the type of motors you will likely be running. There are several options, worth contacting them for info.

Controller technology has certainly changed with "electronic" controllers replacing resistor based units..............in very basic terms, the electronic controllers have a variable sensitivity pot/knob built in which (again in very simple terms), acts like having adjustable "ohm" settings in the controller, to work with a variety of motors.
