Is it possible to obtain slightly faster motors for an SCX car?

The standard motor is too slow for my Scaley digital setup.

I think the 25K SCX motor will be too much for the digital chip. Ideally I would like 21-22K motors.

Can anyone advise?

Start by changing the pinion . If you need to change motor it may be worth considering some of the £10 cars that are currently in Pendles and Top Slots . I think some of them feature a "hotter" motor and even if you only use them for the motor you can't fall off with a new car for a tenner !

SCX motors have a long central pinion rod, so whatever you fit may have trouble reaching the axlegear.

Maybe an Scalextric/Scaleauto/MRRC FF tiny motor will reach, butnd you'll have to buy smaller diameter pinions (only in the Scalex Sport' spare range for a lot of $$$. Then you'll have to find a way of fitting the motor to the chassis and maybe even cutting down the rather long pinion rod!

Cartrix also do motors with extended pinion rods and extened pinions with an added piece of rod, but hardly any retailers stock Cartrix and their stuff is ridiculously expensive sine the global economy stuffed up the slotcar industry by forcing manufacturers to hike up their prices.

Or you could try to sleeve the rear axle if you use a SlotIt/SCX adaptor and a standard S Mabuchi motor. I think it'll have to be can-drive for these cars?

Another thing to think about is that I have 4 SCX cars I have with the standard RX41 16000rpm motors and all of them beat every standard 18000rpm Scalextric stock cars I have bought over the last 3 years. This is because I have swapped out the stupidly over-powerful SCX magnet and fitted a lighter one. This creates less drag on speed and acceleration and much more responsive racing.

Of course, if you are heavily reliant upon massive magnets to keep you cars on the track then you'll have to try:

1. FF can motors

2. SlotIt/SCX adaptors and axle sleeving to greate a gearmesh

3. A desperate search for the right Cartrix motor or extended pinions (try Gaugemaster in England first)

It's just easier and better to buy a few thin magnets on Ebay and replace the overly powerful ones that SCX fit!

I doubt the "hotter" motors fitted in these later cars will be any better, because although they are all rated at around 16-18k, SCX motors are designed to run on about 16volts, Scaly digital produces about 10-11volts at the rails depending on your setup so they just don't hack it.
Slot.It still make an adapter (part no SISP08) so that you can fit a mabuchi motor into an SCX car, unfortunately the pinion shaft of a Mabuchi Motor is not long enough to engage in the crown gear so you will need an Anglewinder axle stopper or spacers to keep the axle/crown gear in the correct place. Apologies as already stated by screwneck
I have found that a Scaleauto Yellow Can (25k) is a good motor for this application provided you fit the ferritman to the motor end of the leads. They are also fairly cheap in comparison to the more mainstream offerings which I have found to be a bit too demanding on the standard Scaly chips.
Regardless of what motors you end up fitting don't waste money on Magnets! fit some decent tyres instead, P6s work best on Scaly Track
Hope that helps

Thanks for the info guys.

Havig looked around I see there is an SCX Pro motor at 23k . I reckon I could get away with that.

Anything I need to know about these?

The easiest option would be to swap the 9T pinion for a 10T one. This should give yo comparable speed to a scal car. The SCX has extra torque but lacks RPM, so the pinion change will help.

Of course another option is to enjoy your cars the way they are . For instance the SCX MK2 Escort is one of my favourite cars and great fun to drive but not as fast as some of my others . All cars aren't born equal . Just race similar cars together . It doesn't have to be fast to be fun !
But first off try the pinion swap , you may be surprised !

All of the SCX cars I tried to digitally chip barely moved after the chip was installed so I am not convinced that changing the pinion is going to help.

OK next question. How do I get the motor out of its cradle in order to remove the pinion.

My Parma pinion removal tool cannot get to it as it is.
