The brushless is more efficient and a lot less maintenance.
Cost more to purchase yet will out last a brush 10 times.

Also aside from Mod racing there is some problems mixing different manufacturers is stock racing. It seems to please most you would have to run one brand or the other from club to club.

Electric "engines" are called motors for one


A normal speedo CANT run a brushless motor, The brushless can run bolth, And thats the cost in BL (brushless) is the speedo, there about 200 bucks, motors are 70-100 bucks

BL motors RULE!!! There SOOO smooth, no maintenance, No heat fade given it has a sintered rotor.. ETC

this may sound stupid, but will a BL motor work if you used an on/off switch, or does the ESC have to do anything special? Like the old dragsters that used a micro switch to turn the low turn motors on.

Edit.
Now that I think about it more. There is no spark, so the speed control may be converting the DC power in some way.??

{Since brushless motors are essentially 3-phase AC motors that are commutated electronically, a brushed motor speed controller cannot be used. Each brushless motor has 3 power wires instead of the 2 found in a brushed motor, along with five sensor wires, that allow the motor to tell the controller where it is. These sensor wires take the place of the commutator in a brushed motor, and do the same job. The advantage to a brushless controller is that there must be a minimum of 6 mosfets (Aveox controllers use 12) to commutate the motor. This makes the effective ON resistance lower than a typical brushed contoller and therefore it will stay cooler at high power levels. }

I got this off that aveox site.

It almost sounds more like a stepper motor, it sends feedback to the ESC as to it's position and that allows the ESC to respond... I don't know much about BL but I'm trying to learn, because I'm building a few drag cars and I want SPEED!!! The catch is even BL isn't fast enough stock.
