A few years back I read about a controller or a kit. This thing would make the brakes turn off on a track call (track power off). Ensured that the car would coast. I wish I would have printed that out to save it.

 

Anybody know about that?

Brakes don't work at all when the power goes off with any controller and you can simply keep the trigger pulled to avoid going back to the brake band.

Bill is right. Just hold the trigger down when the power goes off! Your car will coast. I have seen a few races decided by the coast.

It should be simple enough to put a relay in the brake circuit; closed when power is on, open when power is off, but it seems like a lot of complication for little gain.

True. Doesn't happen if you are on the brakes when the power is cut off, though. I read about the product and thought, so what. Now I'm racing oval, with a whole bunch of track calls. A guy could  get another lap with a device like that. A relay, maybe?

Like guys said, no power, no brakes.

When I do a track call, guys fall off all the time, in turns they hadn't been at all, because they lose their brakes.

What happens at a track call is totally predicated by what you were doing right before the power went off.

If you are full trigger on the straightaway, you coast a long distance, especially with an FK motor with short brushes.

If you are braking for a turn, just as the power goes off, no circuitry is going to negate the dynamic braking action that has already taken place.

Well,

 

some of you are dead wrong. My controllers have brakes even when the power goes off. In some classes it can be a death-penalty not to have brakes at track-calls.

And of course, in other classes coasting when the power is off can win you the race. And of course a modern controller should allow you to do that. I can name one.

Any controller that does not have functioning brakes when the power goes off is not working properly or is poorly designed!

 

If you want no brakes hold the trigger down.

I thought that when the wiper button is on the brake band, it shorts out the motor. Brakes. Makes no difference if track power is on or off? Most times I am on the throttle for track calls. Get a good roll. A few times, though, track call happens while I'm braking. Can't get back on the trigger fast enough. No roll. Win or lose a race by 2 feet and you think about that roll.

If you don't have brakes with power off, and you are charging into the deadman and power goes off just as you are hitting the brakes.

 

Your bent car can be put back on the track but how well does it run now?

 

That's not to mention every time you come off and the track call takes longer because you had no brakes and your car had to be put back on in addition to the the one that started the track call.

There is a racer that wanted me to put a push button on his controller to allow him to coast when there was a  track call. Never got around to it.

I stand corrected on this.

My super-dumb comment was based on an 11 hour day, hustling to the movies afterward, and exposed to, too many 7 year old racers who never hit the brakes.

Hey Mike, I feel your pain. I worked 7 days a week for over 20 years. After a while you don't know what day it is. Every day is Monday. Thanks to everybody for the input.

Because of most of the reasons mentioned above, we recently changed our track wireing. We added relays, so that the two braids are shortened when the power is switched of. All cars will brake and do not hit any wall. No one will coast, with any type of controller.
Seems to me the solution most fair.

In order for a track in Denmark to be approved for hard-body-racing at a national Level the track will have to equipped with relays that prevent coasting when the power is off. It is preventing some crashing and is also preventing several changes in the race-results after the power has been turned off.

Guys with 3rd eye controllers have no brakes when power goes off.
Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream.
