1/10 rc brushed modified motors
Discussion
It’s been a fair few years since I run a rc car. I’ve recently dug out my old stuff along with some old brushed modified motors.
I have a Parma modified cyclone 2 13 turn double.
A kyosho gold Lemans 480 gold
and another kyosho Lemans 240st.
Looking on eBay there are so many variations to choose from with windings ranging from 12 to 55.
Can these new motors be directly compared in performance to my old stuff?
As a kid my grasshopper ran a Parma k stock with a 8.4v hump back battery. That was quicker than my buddies boomerang with a 7.2v powered technigold.
Are the new Chinese modified brushed motors just as good or better?
Any advice is much appreciated

Brushed motors have come on a fair bit, for example the Technigold is listed at 19K RPM which was considered quick back in the day but the current Tamiya 23 turn Supertock can hit 27K.
However more modern motors are brushless and you get the same performance as brushed for less turns. If you are seeing cheap low turn motors listed on Ebay these are probably brushess but they will overlap so check first because this will dictate the type of ESC they need to run.
Ultimately it depends on what the car is and the intended use, if you are looking to get an old 1/10th buggy type car going again a modern brushless motor will blow the gearboxes to bits and I would stick with something comparable to their original design such as a decent low 20 turn brushed motor.

Thanks for the replies . The cars I have are not what I intended to buy but it’s all good fun and keeps me out of the pub .
I intended to buy a new tamiya holiday buggy but bought a second hand Subaru brat chassis instead for a sand scorcher conversion. My daughter was going for a 4wd but preferred the doughnuts the rear wheel drive car does so happy days a rising fighter has been bought.
As both cars are lightweight if a little basic I thought a regular brushed motor rather than brushless but a new modified version. My old brushed motors will be display only once they have had a wizz in the newly built cars as a comparison test.
So the Parma I have was a quick motor in my optima mid even with a smaller motor pinion and running 8.4v nicads. Can I get similar performance from a new brushed motor with a 7.2v battery?

Both of those cars are basic designs from yonks ago, stick a Tamiya Sport Tuned in them and you won't go far wrong, plus that is the fastest motor you can run on the stock Tamiya ESC.
I have a Futaba Esc that used to run my old Parma 13 turn cyclone in the optima. So will use that for the time being. Regarding chassis I like the old tamiya basic designs. I’m not racing. Just a bit of fun.
My daughter had a tentative go this morning of her newly built rising fighter and even with a 35 year old standard 540 motor it was a bit quick lol. She was keen and did listen so no breakages as yet.
I’ve got a 10 tooth pinion to fit but I need to make a little mod to the 380 motor mount to use the 540 motor.
Regarding brushless motors, postman arrived this morning with a hobbywing brushless Sensorless speed control to run a 2845 sized brushless motor. I had already made an adapter for this motor to mount in a 540 motor position.
It’s a 3930kv 380 sized motor fitted into my optima mid with a 7.2v battery and wow! That little motor shifts that car! I bought a 60amp esc but the motor or battery didn’t even get warm during operation so I reckon a 30amp esc would work perfectly well and cheaper to buy also.
Performance wise this little brushless motor and using a 30 amp esc would cost £40 and has the option of using a LiPo battery. Maybe later in the year I’ll give that option a go.

Modern brushed motors are fine. But many brushed ones from years ago were for racing. So maybe a little more QC and better performing. I have a Parma modified cyclone 2 13 turn double.

I have a load of 11 turn brushed race motors from yesteryear. Some new in packaging.
The biggest issue is good ESC’s to run them. Many of the new budget ESC’s don’t handle low turn modified motors. And older ESC’s don’t always work well with Lipos unless you run an external timer.
I have a couple of LRP ESC’s and I’ve tried using 2S Lipos with 11 to 9 turn motors. But the wires keep coming off of the motors. They are soldered well, but it think the current the Lipo and the ESC can handle is too much.
Brushless isn’t the be all and end all. And they really aren’t massively quicker on 2S. The gap isn’t really as big as some will make out. Runtimes are usually better though.
I’m still running a 12x6 modified brushed motor in my Tamiya Lunchbox with an old Novak Tempest ESC. It seems to run really well and is easily as quick as some of my brushless setups.
But you can buy some brushless setups pretty cheaply these days. You’ll want a sensored setup to offer similar throttle control to a good race brushed setup. Sensorless brushless works fine, but the throttle control is far less precise and much more on/off sensation.
Lipos make a big difference though. Even a stock silver an Tamiya brushed motor (27 turn) runs pretty good with them.

That lunchbox does wind up really quickly 👍. I do prefer the quick acceleration car. My old optima has a small pinion fitted and winds up rather quickly. I fitted that tiny brushless motor out of curiosity to see if it had the torque as per my old Parma modified and it certainly does 😊.
I’ll try it out soon in the rebuilt brat chassis. I’ve shimmed and rebuilt the gearbox with no slack or wobbly drive shafts. The front end has had the same toolmaker treatment and is now play free also. Much easier doing model cars rather than full size lol
I’ll post some pictures when the bodies are properly finished 👍

I meant to ask, the lunchbox wizzing around in your video is it still using the original 10 tooth motor pinion?
No. I’m running an adjustable motor mount and a different pinion. Afraid I can’t recall the tooth count though. Gassing Station | Scale Models | Top of Page | What's New | My Stuff
