Well.....
ABS is a braking system.....helping you retain traction for consistent braking so the car does not lose control. While it does have a traction element to it, it's a different system all on its own.....
Traction control on the other hand is based on wheel spin during accerlation.....you are starting not, stopping. If you can control power output to provide the optimal amount of grip and accelaration.....you've got a functional traction control system.
Long and the short of it....thats why my ferrari has both traction control AND ABS, as do lots of other top sports cars....they are two totally different things. If they weren't, companies would not design and produce them as two different systems....

This is a really simple concept, the terms "ABS" and "Traction control" are just labels. Don't let them confuse you.
Obviously they are different systems, but they are basically doing the same thing in different directions. Both systems exist to optimize wheel slip in either acceleration (traction control) or deceleration (ABS). How are they totally different?
In road cars, deceleration is done by the brakes, while acceleration is performed by the engine, thus there are two names for the different systems, ABS for the braking system, Traction control for the engine/throttle system. In an R/C Car, however, both the braking and the acceleration are controlled by the motor. Their distinction is even less.

Regardless of how or if traction control/abs can be done. the point is ROAR just allowed brushless motors the option to explore it without having to go through inspection,price limits or limits on magnetic materials. Uneven playing field bought and paid for.
Boycott any company that is supporting someone running these prototype systems at the nat's.

in responce to the very first post, ---- isn't that what they are already doing at most races anyway. don't most guys in the a main at major races have cherry picked batterys and motors now. i don't really see the difference. and no i'm not taking about races with hand out motors. but whos to say those weren't dyno'd and cherry picked also. i know i don't get to pick my motors they are assigned to me.
as far as this post goes,
------Considering I was the first response, there was no "entire" posts to read.... ------
it seems to me that you once again failed to read the post correctly.
----------Read the entire post before replying. -----------
this was not asking you to read the entire "thread" just the entire "post" (no "s")

Like I asked in my previous post, HOW does it detect wheel spin? Measuring the drivetrain/motor speed doesn't tell you if the tires are gripping or slipping. Having a sensor on the motor does NOT in itself provide enough information for traction control. [/B]

one way that is possible is by measuring amp draw and the motor speed.

I said this before, this will not provide enough information for traction control! This only tells you how hard the motor is working, not the amount of slip the tires are experiencing.

There are too many misconceptions regarding brushless....
Whether or not he WROTE the post, He QUOTED it....
In the end we still play with toy cars....
If anyone would like to resort to any kind of name calling, PM the person directly...
