Race results in Europe and the UK over the last year sum it up - brushless dominates in open class.

It took a while for the tech to match brushed, now it has matched and surpassed it.

I would have to agree, that once guys learn the B/L motors...they are getting faster and faster. Although I have seen some guys bail on the mid range motors and go to the hotter ones to get there...personally I don't think they ever hit the right gearing with the mid range ones...and they would have probably gone just as fast.

Almost all of our MOD guys are now switching over...some of them don't want to give up their motor tinkering...but admit it so much sweeter to strap that motor in...instead of having to cut it...brush it...and play with it to make it fast.

Normally I run brushless, but last wednesday I tested the whole day with a 7x1 brushed motor.
The guys with the brushless motors had much more power out of the corners.
Top speed was nearly no difference.....

i run a 10.5 in the 19t class. as far as "faster" goes, it's about even with a good 19t. as far as "quicker" though, i think BL gets around the track in less time. it's got more torque than brushed and doesn't have nearly the drag.

but for me it was ease of maintenance and reduced racing costs. the up-front cost is only a little bit more than a brushed motor, speedo, and a few sets of brushes and springs. the race day cost of brushless is basically nothing, the motor runs the same every run, and i have more time to focus on the chassis.

I've put all my brushed stuff back in my cars to start getting ready for the nationals, come on down tomorrow and I'll show you how I can SPANK you with brushed just as easily as I have been with brushless

Well, since your main question is about speed.... the worlds fastest RC car (including nitro cars) is brushless. 134 MPH is the record I believe. And no maintainence to boot!

the BL (stock/13.5) guys at my track got alot more pull out of the corners...top speed can be similar but...w/ the BL you can gear it higher... so the BL guys still pull away down the straights. my 2

Not just faster, but more efficient. When they do the 24 hour enduros, they line up brushless motors and you may have one entry that uses brushed. Just think about that...24 hour run, slap a motor in, no break in, no brush cut, no timing to adjust, no hung brushes, uneven brush wear, no comms to cut, no lathes, no extra anything. I dont know why guys who arent sponsored are holding on to a losing battle. If you arent a factory dude that gets motors in droves to tinker with, then why go through all the hassle? Soldering brushes, adjusting timing and spring rates, brush break in, less run time, comm sticks. Just the list alone is low speed and high drag.

If brushless is allowed....it can be geared up taller (faster) and more torque...in any spec (13.5 10.5 and 4.5 3.5...etc)
But most national races are still under BRUSHED motor rules except MOD and Novak Race...

the big "difference" is in their efficiency, not speed... that's why the europeans use them. they run 5 cell and need the runtime...

Brushes are for cleaning. J/K Unless you got a lot of free time, stick with brushless whenever possible.

I don't anybody that has willingly switched back to brushed after running brushless more then 5 minutes. What is there to debate? Better, better, and more better. Mixing the 13.5 with 27T is going to be a touchy subject until the stock guys finally let go and just get on with it.

Try it and you won't go back.
