Controllers

[VenturaAlfa]

Hi Randy,

I got a little out of control (OK A lot) when I came back into slot car racing. Off the bay I bought Parma controllers that were anywhere from 4 ohm to 90 ohm and a couple of basic professor motor controllers. What I ended up finding out was that most, if not all, of the 1/32 motors including those used at commercial tracks other than high end racers responded well to between 25 and 45 ohms. 25 ohm seemed to give the best throttle response with the cars staring to move as soon as I pulled the trigger. If you could set up a 45 ohm that would toggle between that and the 25 and 35 setting that should be pretty much ideal.

If you go that route let me know what you end up with for resistors; I may try it myself.

I am currently using 25 ohm controllers on the home track.

The Professor Motor club controllers worked well also but I had to get the choke kit (I think that was what it was called) where you install bolts and nuts into the controller so that the trigger works normally. They are a good controller but don't actually feel any better than the Parmas.

As to price point, I did not pay over $13.00 for any of my controllers and many of them were under $10 dollars. If you don't want to own a whole bunch of useless controllers like me, resistors can be purchased from several of the retailers on this site for $9.99 or less.

Hi V A. That's one of the reasons that I started this thread so I don't end up with a pile of controllers. After picking up 2 used controllers on E-bay for $25.00 and having the seller refuse to ship any other way but priority for a further $25.00 I now buy new. For the 45-35-25 setup, Peter (pfeutze) has posted the necessary resistors earlier in this thread. I think If I started with a 60ohm controller that I may have better control with the Dslots. The 45 ohm would work for all the Go and SCX cars and hopefully somewhere around 30 ohms would would work with the aftermarket motors. The other option is an entry level electronic. Both Slot it and DS have controllers in the $129.00 range which is roughly the same price as 3 Econo's with the extra resistors and toggle switch, especially if freight (which is approaching ludicrous levels up here) is taken into consideration.

Thank you Peter. I thought that the resistance was to high on the cuda. I've also been using MRRC ff050 motors that act more like bullets that I thought could use more resistance. Would I be correct in assuming that the resistor calculation is an inverse relation and that "if" I substituted a 75 ohm parallel resistor for the 90 ohm parallel resistor that the final value would be closer to 30 ohms.

Thanks Again

That is one advantae of the Electronic controllers; the work with just about any car, so you don't need a 25ohm a 45ohm a 60ohm, etc.

Peters trick sounds interesting though!! I am thinking I need to try that with some cheap set controllers I have that are more like on/off switches!

I think how this is going to play out is that I'm going to build 2 controllers with Peters setup for the 2 lane track and buy a reasonably priced electronic at a later date.

Randy, for the 60 ohm controller -if you use a 60 ohm parallel resistor, you get a 30 ohm controller.
WARNUNG: don´t go under the half of the nominal value, the response curve will get to dented.
i will look for the graph - i think i have it somewhere ....

Thanks for everything Peter. Looks like I now have another project on the to do list.
