Thanks for the info Mark! I run Mega-G+ cars on standard AFX track. As I get back into the hobby in my retirement years, I am finding that I want to upgrade some of my cars, track, and controllers. You've got the kind of videos that are really helpful to me as I think these changes through. Again, many thanks!

Great example of how different ohm controllers affect the way a car will run. Upgrading to a better controller makes your racing experience a whole lot more fun. Thanks for the video Mark.

Thanks for the video Mark very good knowledge keep up the good work I'm going to enjoying all the videos

Great video. Good quality controllers really take racing slot cars to a whole new level of fun & precision.

Very helpful video. I have a several different track sets and cars from different time periods and couldn’t figure out why some cars were janky and some weren’t.

Love the DiFalco’s

Thanks Mark well done... excellent... knowing what you need to do before laying that cash down buying something that will not fill your needs....

Great video. Great advice.

Great information thx you for your knowledge 😊

I have developed a esc and controls with patentomitur triggers it's awesome no more resistance to deal with awesome so many options

thank you. Perfect example why its so unfortunate these are in any sets this day and age; they should discontinue to put these cheap pieces of junk in sets and people all through the community complaining the cars of most all other types don't run right and can't keep them on the track and so on Due t these things. Even if they would put a controler like the old 1974 orange AURORA HOBBYCRAFT adjustable (but with a diff ohm rang) or DS like multi-position type controller, it would be so much better (NOTE: the 120 ohm are not for most all cars but MG+ and vintage aurora T-jets) Those seeing this -- other variable controller options are the Professor Motor controllers> the basic being only $63. the OS3HO LITE.. and actually BRAKES and NOT NEEDED for most home hobbyists playing and using plastic tracks ; evenfor racing for titles and fun - mostly for T-jet FRAY racing or more semi pro or professional type racing on mostly professionally routed tracks, but of course, one can wire the home track for brakes and use these type controllers. All this info and wiring diagrams on the web and possibly some YT videos on it. NOTE: the gray AURORA/TOMY controller is a 70 ohm as are the older tyco and other controllers that came in sets. $63 to 90 bucks is the #1 best investment you can get for your hobby- the cost of only two or three cars these days to have the very best possible HO Slot car experience.

For HO cars with set type track, I've really found that the original Parma controllers with the ceramic resistors are the most ideal. Yeah, the electronic controllers will work fine but they are less tolerant of the varying voltages and lower-than-ideal current so common in home track setups. I also find that the resistor based controllers ramp up and down much more smoothly in how they deliver power across their sweep range. The electronic controllers just seem to be much easier to break than the OG Parmas and let's face it, an electronic controller is a much more significant investment than a resistor based controller. If you race on routed tracks with lots of modded or high power cars, electronic controllers are all well and good. I find myself wishing they would bring back the old Russkit set controllers. Those things were built like tanks and they were pretty affordable... and user servicable.

This is why I can only run the mega g plus car with the controller that my afx track came with originally it came with a 120 ohm controllers for them and they run perfect with it but when I put like a tyco on it it's real erratic and takes almost full throttle to get them going so now I know I will need new contollers. And it seems like the cars go faster when you get the right ohms going to it in the controller to I will need to buy a adjustable controller I saw where a guy made a variable controller for 10 bucks and worked great

great video as i just bought an older ho track and am finding it difficult to control geese stupid things. the ohm difference is the big question

Professor motor controllers with independent lane chokes and sensitivity adjustment is what I run on my road course and Parma on my drag strip…. They are both larger and feel better in the hand and run just about anything with the lane chokes

Good intel here.!

Good to know about the Difalco 505 controller to get my Grandkids used to those simplified way to get them to move into the AFX Racing and move them up The Aspect how to use controllers better good job.

I have (4) of the 505s without break. How much difference do you notice with the braking feature on the Afx track? Is it truly worth the upgrade ? Or slightly noticeable? Thanks

Oh yeh... I ran into this as well. Different cars want more/less. I upgraded to DiFalco's most basic controller (no brakes) but I honestly haven't hooked them up yet because I'm still struggling with wiring... uhg

How does 45 ohm do with the Super 7 and Viper Spec (Level 4 > 6ohm arm) car?

For me the easiest & cheapest solution is a variable power supply. My Parma 45 ohm controllers work well on 440x2, x-trac, m-trac and SG+. Variable voltage let's me run the cars slower for the kids too. The math equation is simple V=IR. Way cheaper and more functional to vary the voltage instead of the resistance.

Hello I have a AFX MEGA G+ track. But my viper cars don’t run as well. Is there a controller that works with all 1/64 scale cars. All options welcomed thanks in advance.

Hi, great video, Just bought a Victory 400 track. I also bought 4 viper 6 ohm vipers 1 and half ohm viper, 2 an half ohm viper The vipers don't work very well with the stock controller,. Would I be able to use my 1 to 4 ohm 1/24 scale controllers on these cars. I used these controllers to run group 7 Koford cars,

Are there many adj between low ohm and hight ohm are they easy to adj

Where did you find the 505? I can't find a 505. 500,201,502,504,506,507 are available but no 505.

What height is your track table?

Your power supply will work fine

This isn't just true on ho my 1/43 cars with stock controllers are taking of at 3/4 of throttle.
