Carry more speed into corners for a faster lap time - fit anti-brake to your slot car controller
HTML-код
- Опубликовано: 6 сен 2024
- With slot car motors becoming faster and more powerful you sometimes have too much braking effect to drive a smooth and fast lap. You can now solve that problem by keeping the high torque, high brake motor and adding "anti brake" to your slot car controller instead. It can make your slot car so much easier to drive and improve your race performance.
Components you will need...
500 Ohm potentiometer - uk.rs-online.c...
On-Off-On toggle switch - uk.rs-online.c...
Strip Board - uk.rs-online.c...
68 Ohm fixed resistor - uk.rs-online.c...
You will also need some flexible wire (Slot car lead wire will do)

Thank you for this video, James! I have also performed the same mod on my controller and others as well. WARNING! If you use a late model DiFalco with brake bypass (ESP), you must use a triple-pole switch so you can interrupt the ESP when engaging anti-brake. I do add fans to the heat sink as well.
Thanks. That is good advice for anyone wanting to add this to their DiFalco. 👍🏻
It is worth drilling out using a old 1/24 wheel and fitting it over the switch lever to prevent accidentally switching the position of the brake when you put the controller down, and ending up with no brakes unexpectedly, walls are hard. That used to happen to me all the time.
Nice idea Mike 👍🏻
Amazing, thanks for your explanations
My pleasure!
Think guys call this different names, I used this last year ( manufacturer called it a different name), it made helped me to become a better driver. Thank you for showing the drawings schematics I may just try DYI . don't miss this this one Boy's. Been racing for years , it helps, thank you cleaveTech ...
Thank you for watching 😁
That is cool. I could guess the gist of how it would work, but having it explained is awesome. Thanks for the time man.
Glad you enjoyed the video 😁
Nice mod. Should work a treat for HO and magnet cars, or cars with a great deal of brakes.
Yes. I haven’t driven an HO car with anti brake but I think it would be good 👍🏻
Another interesting and useful video. Keep up the good work James! You wired this a little differently than I expected but I can see the advantage of wiring convenience in doing it this way.
I can’t understate how important it is to add a fan to your transistor when doing something like this!
You must have seen the next video then 😉😂
Thank you so much. James
Hi James I'm very new to the hobby. Had a question. Can this kind of mod be done on a Palma controller with the wound resistor? On do you need a board with the resistor network? Sorry if I sound stupid
hello There again !! thats cool....actually the circuit is in parallel from the graduation and goes to the transistor base modulation. I personally dont like using the same transistor for both functions- it heats a lot !!!! - I did mine difalco upgrades using 2 or even 4 transistor - individually for anti-brake feat - in this case i had to use 8 wires cable instead of 6.
Thanks for watching and commenting again.
I understand that this method does mean that the transistor is on when the car is possibly not moving, but I have not had any issues with heat. I use a big heat sink and I very rarely have to turn the fan on.
Its not only heat...its tha way it forces the transistor modulation - its actually 2 modulation levels on the same transistor. one from graduation itself and another when you use anti-brake feat
Only when your on brakes will this be an issue. when you add throttle the antibrake signal should turn off
Dave - i didnt say that. I related the problem for transisor modulation - both for graduation + anti brake using one single transistor. I use 2 - one dedicated for anti-brake (8 wires cable instead of 6). The circuit runs individually for the anti-brake this way
@@ACCOUNTANTB Can you expand on this? I have a Difalco I would like to add this feature to. Maybe use time stamp # if this controller relates.
Hi James great video. Can this be fitted to a Kobis controller. Will it work the same.
The Kobis uses a similar circuit but I think he uses an NPN transistor so you might have to play around with resistor values a bit.
I loved the job. what price would it have to make a controller, exactly like that.
I have spent over 10 hours on this controller adding all the features. It would probably take another 5 hours to build the parts that were already built. You would then have to add the cost of parts on top of the time spent. I can fully appreciate why controllers cost a lot of money to buy. There was an English guy called Bob Budge who developed an economically priced controller that was really good, but I don’t think he makes them anymore. ☹️
Have you got part numbers or links to the items needed please
I thought about finding links to all the components but they are simple to find and the links would probably only be valid for short while. I will add a list to the video description 👍🏻
What is the other blue pot being used for?
The other pot is the sensitivity adjustment or sometimes it is called attack. It is shown in the overall controller circuit diagram.
Too bad they're far away, otherwise I'd send them my control so they can do the same for me.
What Controller do you have?
I tryed it recked my controler had replace lot of it so don't work on all late ones
Sorry to hear that you didn’t get it work on your controller. Some controllers have the wiper insulated from the brake and full power. Maybe your controller was like that? I will be doing a short video of an alternative solution soon.
