Brakes not effective

[Dudders]

Hi all,

I have a speed passion ESC with a control box for set up. Just found the time and courage to have a fiddle as I wanted more brakes on neutral.

However, I think I've set up everything to maximum and still the car rolls. Surely in neutral (or a little reverse stick even) it should stop the drive wheels in an instant.

What am I doing wrong?

All words of wisdow and other greatly welcomed as it reet doing my nut in! :confused:

Make sure it was the drag brake you adjusted, not just brakes.

[Dudders]

Drag Brake (2) set to 8 = 50%
Max Brake Force (5) set to = 4 = 100%
Initial Brake Force (7) set to = 4 = 40%

Cant see what's wrong.

Couldnt be T/X issue could it?

1) Set the transmitter EPA's to 100%.
2) Set all brake curves to linear
3) Re-calibrate handset with ESC.

Then retry...it could be that the ESC doesn't know where neutral is properly, so is not applying drag brake effectively.

Hope this helps.

Will try 1 and 3 in a bit after putting the kids to bed. How do you do number 2 though?. Cant see a setting for this? :confused:

the wheels shouldn't stop instantly in neutral, thats why its called neutral to stop wheels dead you must use break, drag brakes are only to give the effect of a brushed motor,

Ok fine, didnt know what 'Drag Brakes' did - understand now. This appears to be working.

However, What I want is some braking effect in neutral postion of the stick without the need to pull back on it.

Something that isnt happening, or is it not possible? :confused:

mattys settings are
Max Brake Force (5) set to = 4 = 100% 4wd 3=75% 2wd
Drag Brake (2) set to 2= 5%
Initial Brake Force (7) set to = 2 = 0%

drag breaks is the setting for some more breaks in neutral

[Dudders]

So what about braking on reverse stick?

[bigred5765]

thats just max brake force 2wd we use 75% 4wd we use 100%

[Dudders]

Right, thanks all. Looks like the ESC is set up ok. Perhaps its a t/x issue as it make no difference to stopping times if I just flick back to neutral or reverse stick :confused:.com

Is this bench testing, because on track you would see a difference.

[Dudders]

Not exactly bench, but a 20ft long hall way on carpet, which I would have thought would be enough. I'll leave it till Monday and see, Ideally I'd like to get quite a bit of 'slowage' upon releasing the throttle :eh?:

[johnb]

I've got mine set to

Drag brake 2 (5)25%
Brake force 5 (4)100%
initial brake 7 (3)20%

And I'm getting quite a bit of drag brake when just holding the car and letting off the throttle.

So would have thought with the settings you have it should stop the car pretty quickly.

The other thing might be the Neutral range which is setting 8 as have mine set to (1) 6% as this puts the throttle response and brake response very near the neutral on the stick.

[AdamBurgess]

my speed passions brakes are a bit crap too. Did a tx reset on the model number, set the neutral, full throttle and full brakes as per the esc set up intructions and it doesn't stop the car instantly. there seems to be a delay in the full braking power which in itself isn't very strong.

I'll keep the Neutral range in the bag until Monday... so will let you know the result :thumbsup:

This is my concern. I would have thought on full brake settings and full stick it should stop on a 6 pence, but it rolls on quite a bit :o

[bigred5765]

reset esc forward brakes and neutral as you would on new install, make sure you hold each position while pressing the button for each setting, then check slipper and diff make sure there not loose

I had the same problems with the brakes on 4 different hobywings (which i think are the same as a speed pasty) after pulling my hair out which didnt work, a very helpfull friend re-set my epa's on my transmitter then we tried programing 100% reverse although not using reverse. cured the brake problem:bored: it seems you have to program a value in every setting even if you are not using it.

[Dudders]

Ok, gone back to basic reset and selected everything brake to the max. As soon as you take your finger off the throttle the wheels stop and the beast grinds to a quick halt.

Now, this proves it works. The car also needs more effort to be pushed - you can feel the force of the motor.

However, pulling back the stick still does nothing. So the ESC is working but maybe not set up to the handset correctly :confused::confused::confused:?

[Timee80]

as said above, set the reverse to 100% even tho you probably wont be using reverse anyway. Now set your brakes as you like and everything will be ok. For some reason, you need maximum reverse to enable maximum brakes:thumbsup:

[Dudders]

what setting are you calling max reverse?.

I've now got it all on Max and it stops on a sixpence when you release.... but from what I can see nothing on reverse stick. Perhaps the natural brakes are on too much and you dont feel the reverse power - But I don think that's right.

I'll fiddle a bit at the next meeting. What I have now is a vast betterment than before, would just like to slacken the mid braking a little and have a bigger effect when pulling back.

Think it might be a hands on job for an expert.

Set the drag brake to zero and the initial brake to equal drag brake. Leave everything else to the max and you will have progressive but strong brakes through the range.
