It seems that I am not getting enough braking force from the stock pads on the EB4 S3. Anyone else feel this way? Using stock brake disc and 645MG servo.
 
sorry to ask, but you do have the linkage set all right???
do th ebrakes lock the tires up when you apply and you want it to brake faster or do the wheels not lock up and you want to brake faster??? I've only seen one of the TT buggies run ( it was bone stock) and it seems to be really good on the brakes w/ a hitec servo in it.....what are your's doing exactly? cause it could just be a linkage setup....
 
my S3 brakes are awesome. check you linkage, servo arm placement on the servo, EPA's. My brakes lock up no problem at full input and with my ABS turned off. No complaints here.
 
I have the linkage set up per the build manual. I have since adjusted them to come on almost as soon as the throttle comes to full close, instead they just seem a little weak. Yes, it will lock up, but I like it to be more 'grabby'.

I did all the EPA's and have double checked there is enough travel on the servo in that direction.
 
so you're sayin they seem to go from nothing to locked and not much difference in between? I noticed that on mine. I don't know what kind of radio you're using but I turned my brake exponential waay up so they felt more progressive. I think my exponential is around +50%. This way it they activate alot at first then quickly level so that a lot of brake throw transcends into very little actual brake throw. much much better. If you can't adjust brake exponential on you're radio maybe try replacing those springs with a small amount of fuel tubing. that may make it feel a little more progressive. Fuel tubing is kinda soft for buggy application I think but if you happend to have some gasoline fuel tubing that would be better, it's a bit more stiff than nitro fuel tubing.

I have an MX3-S Tx, so yes, I can set the exp. I will try that. Thought of it, but thought it might be the material they use. Also, I see what you mean about doing up the body. What a PITA that was. Thank God for Dremel.

And as far as steering, pretty good for pillowball. Feels 'heavier' than my Hyper PCR, but real strong. Little bump steer. Couple of small things and I can take it to the track.
 
Brakes were so powerful that I almost flipped it the 1st time out(Mine is a full race set up). Steering is incredible, Of course i am using an 8611 servo for steering.
 
See Sarge, that is what I mean. My T-Maxx WILL flip if I hit the brakes to hard, and my Revo will lift the rear wheels off the ground if I stop hard. The TT seems to not grab as much as I like. I'll play with the exponentials this weekend and see if that cures the issue. My PCR stops better than this TT!

I checked to see if there was any binding either in the brake pads, or discs, or in the linkage. None. I even raised the endpoints on the brakes and no difference worth anything.
 
i doubt its the exps more likely you need to have a play with the brake curves instead, so its smooth through the curve and only locks at full trigger
