They were my first upgrade. Can't drive the car with only the original brake.
The front disc brakes will provide the braking that you want, if u use them to "tight" they will stop in seconds (lock the wheel), if u run them loose. the only help the rear one stoping the car.
They are a great upgrade. They will double your braking power. It will also allow you to put less stress on the throttle servo lessening the burn out/failure chance. You will need the following:
Front brakes. 6250/3 or 6250/7 - $140.00
Alloy front uprights. 6103/6 - No others. - $107.00
It is nice to have a 3ch radio.
im running a Hitec 645MG for the throat/ rear discs and the same on the fronts. im think i may put all the brakes on one servo and upgrade the braking servo for the brakes to the JR Z9000s on the Bergs.
I already have the alloy uprights so that no big deal.
as for the 3rd servo I can see the function of it other then having two servos for power.
If i run it in the 3rd channel in the receiver is there a way I can mix the channels so both 2 and 3 move with the same motion on the remote?
I remember reading something about this with my old 3PM radio but I now have a Spektrum DX3.
