RE: controllers 101 - OXO cube - 2nd-Feb-21

thanks guys

after more internet delving
i think i understand that the ohm's affects the initial trigger input ( lower ohm = more power initially ?), since the max power is a constant

and then letting go of the trigger in effect turns the motor into a dynamo therefore slowing the motor faster which in turn stops the driven wheels faster creating brakes

are these the 2 knobs seen on some controllers that can be adjusted ?

is this correct ? or have i got it wrong again hehehe

Hello Kev,

Yes, your summary above is the essence of the dynamics of a slot-car power train.

Firstly, let me reveal that I have only once used an electronic controller (Scorpius WAM).
To my understanding, the fundamental benefits are analogous to the computer control in high performance road cars.

1 - Power delivery from the engine is controlled by electronics so that when the driver "stamps on the gas" the driven wheels are not allowed to break traction.
2 - Braking effort is controlled so that when the driver "stands on the brakes", the wheels/tyres do not lock up and lose adhesion with the road surface.

The knobs on the slot-car controller allow the computer/human to pre-set these aspects to suit the car/motor, track and driver skill. In a 1:1 car, the system is "closed-loop" type where the computer has feedback from sensors at the wheels and can detect wheel spin and/or lock-up, and nowadays, the power distribution to each wheel can be governed.
With slot-cars the system has no feedback and therefore has to be regulated by the driver's pre-judgement.
Some of the benefits are:
The same controller can be matched to cars that have hugely different motor specs.
The delivery of power to the driven wheels is more consistent than simply having a human finger on the trigger.
The releasing of the trigger is smoothed so that "coasting" around curves is smoothed rather than sudden braking.

The set-up is a compromise matched to the flavour of the track layout and of course there is a learning process as the driver tunes in to how the car will re-act when the knobs are twirled.

thanks Leo
good to know I'm heading in the right direction
was always going to wait until a club is open before i made any purchases
just wanted a bit of clarity on things ... been wondering for a while lol

thanks guys for your input

Not "1.01" territory, however.
If you are considering an electronic controller,

Looks like you are in the UK so....

No need to worry about this ,that and the other. For analogue racing the answer is buy a Truspeed PWM Rofl

Pulse Width Controllers – TruSpeed

If you want to elevate your Scalextric digital control, when I started I had digital and had the early version of this: SSD III Digital Slot Car Controller – TruSpeed

I have no affiliation with them other than being a happy customer for a good few years, and finding the customer service to be top notch Yes

definition of 101 :- It is usually used when someone gives or asks for a “beginner guide” in order to teach or learn something new.

So you would be in need of an Intermediate and Advanced posting? Which sounds like a great idea.

I've been having podium wins with my TruSpeed PWM controller now for some time, the other week I grabbed the controller that another racer left plugged in for a quick car test and was amazed how smooth the trigger was, so now I'm weighing up do I buy a Slot.it SCPII or still get the TruSpeed Apex controller or both.. as I don't have a spare controller currently

RE: controllers 101 - autoavia - 10th-Jun-21

For what it is worth I borrowed a Truspeed PWM for a few club nights and the 2019 Policar GP after my Carsteen went u/s and I didn't like it.

I am sure it is a good controller and others are obviously very happy with it but it just didn't suit me which just emphasises the point that it would be very useful to go to a club and ask to try other members controllers before committing to buy.

I race modern Hardbody and Vintage cars so I will look at the new Truspeed Apex once it has been fully tested on all types of cars but I do think that it is bound to take a while to learn to set up all the variables that the Apex offers.

RE: controllers 101 - Fluff - 10th-Jun-21

I have just bought a SCP2 and I am very happy with it , if you get used to couple of settings before trying everything at once you should not get into confused state ...although most things confuse me now .!!!

I agree with what autoavia (sorry didn't get your real name) says about borrowing a controller that you are interested in from another racer.

I love my TruSpeed PWM controller, however I am looking at investing in five of the SCP3.0 controllers, four for my track and one for myself after having a quick minute use with one that was plugged into the drivers station, the trigger is sooooo smooth even compared to the TruSpeed PWM I currently have.

I too am waiting for the TruSpeed Apex controller to arrive to test and see how that improves my racing.

RE: controllers 101 - Qman - 10th-Jun-21

As I think I've said before, I have a Truspeed, a couple of electronically converted Parmas, a Sid Jensen special, a Birdseed special,and 2x ECE Rockets (thumb) converted to electronics.
In order of preference I go:
1. ECE Rocket (I am and have always been a thumb person)
2. Birdseed special (smoothest controller I've ever used)
3. Sid Jensen special
4. Parma
5. Truspeed (I quite like it except that if I use a 'hot' motor it will invoke a safety cutout every now and then, I've had the same report from another user)
