Quieter operation
No need to bed in the brushes when new
Performance doesn't change with time (i.e no brush wear)
Longer motor life
More efficient so less heat
Better power to weight ratio
More granular control i.e throttle and brake
Generally cheaper

Reason to try,
person is less likely to die from boredom :) [just kidding]

I'm fully aware of all these perceived advantages but a brushless setup isn't generally cheaper for RTR cars. At ISRA level it probably is where a motor can cost £250 alone and you'll need a few of those.

A Revoslot motor is 10 quid, a brushless setup requires a motor an an E-com to drive it and that costs considerably more than 10 quid.

Besides that, I'm looking forward to seeing you get this setup properly and lapping consistently faster than a standard setup...without magnets. Thumbup

I've used some of those cheap (brushed) motors and they go good, but not for long. So you need to replace it which doubles the cost, plus inconvenience. Maybe I'm just unlucky.
I've not had to replace an R/C aeroplane brushless motor ever. The cheaper brushed motors I've used were electrically noisey and caused trouble with the electronics, no problem if you're only running analog cars.

A reasonable quality brushed slot motor from Armchairracer is circa $28. The brushless inrunner motor I have on my bench for a slot car cost $35au, but cheaper ones are available. Finding one with suitable kv is the challenge, or buy one and rewind it. e.g

[attachment=33636]

The ESC/ECom I'm experimenting with (from a drone) accepts standard Arduino pwm signals as well the usual R/C 20ms. So I'm wondering if I can run the ESC /ECom from the pwm motor output from a commercially available digital slot car decoder?
Also the ESC/ECom has an Atmega MCU and the SPI pins are unused, so a nRF24 module may be a future possibility. Idea

I fully understand if brushless doesn't appeal to everyone.

You may not fly one plane enough. I built an "FFX Park Fighter" Hawker Hurricane for my friend around 2006. He loves it so much, he's worn the bearings out of the Mega Motors 6-turn inrunner brushless... twice! I don't know how. But he never seems to crash that one plane. He still flies it today. It's on its third motor.

He also flew a brushless FFX Park Fighter ME109 straight down into a frozen lake at about 70mph. The rear motor plate almost met the front plate. He hangs it on his wall like a trophy. If you're going to crash. Make it a good one. Too funny.

I definitely don't fly enough these days. Thumbup

I used to always have a model in the car and have a fly on the way home from work when the conditions were good. Lipos seem to get worn out the most back then.
On a side note I see control-liners are now going electric with a timer.

RE: Brushless Carrera Digital - KensRedZed - 4th-Feb-24

I flew a few control line stunt planes and a few .35 combats when I was a kid.

The Nobler = George Aldrich's original Nobler Control Line Stunt model. Mid-wing with I-beam wing construction, no dihedral. Traditional balsa wood framework. Oval-shaped fuselage. Dark blue in color with gold accents. Flown at the 1951 Plymouth Internationals, as well as the 1952 and 1956 National Model Championships. 50" wingspan.

Now Top Flight sells an E-Nobler control line stunt plane. Truly a mix of old and new tech.

Crazy times!

I raced RC cars for nearly 40 years going back to the late 70's (mainly 1/12th carpet but lots of offroad too), through the 27mhz to 40mhz to PCM to 2.4Ghz eras, through the NiCd to NiMh to LiPo eras and through the brushed to brushless eras but the single biggest huge jump was the introduction of brushless & LiPo together which was an instant game changer...there was no way back. Long run times and zero motor maintenance meant more racing and less hassle.

For us RC guys the change itself wasn't so great as the cars already required an ESC and battery pack but the performance was a huge change.

There's nothing in our club rules stopping us using brushless setups but I don't see that same huge game changer happening for Slot cars, it's more of an alternative option but only for some classes of cars until there's much slower motors available along the lines of a 14k motor equivalent?

...as an aside, in those 8+ years of racing Slot cars I've probably had to replace a handful of motors.

Is this just a fun exercise or does your club now have a race class for brushless motored cars?

For me it's just fun and interesting.

I have created an new thread as this one is drifting away from being Carrera focused,

Drifter2.

I humbly apolgize for the redirect to RC aircraft. It was blushless motor related.

Your new thread doesn't mention Carrera at all. This thread started off with Revoslot pics. I'm confused.

Brushless motors are generic and can be made to fit almost any chassis. Why only Carrera?

One more thing. I totally support your experiment and think it's great fun. It just won't ever be allowed at the club where I race at. The guys I race with, prefer slow class cars.
