Ofna Throttle Mod Question

[pnstalum]

On the Ofna throttle mod, I see that some place a spring on the brake linkage to the right of the servo arm. What benefit is gained in doing so? If you did this...wouldn't it apply the brakes at full throttle? Also, what is the benefit of using fuel tubing vs. A spring to apply the brakes?

Thanks in advance!

When done properly, the spring just keeps the slack out of the brake arm/linkage. Just makes operation more efficient. The tubing allows more torque to be transferred to the brakes which equals better braking. Careful though,it get easier to have to much brake and cause the truck to flip frontward under hard braking.

Hmm... when you say done properly, what do you mean? Do you have to implement some type of "stop" so the brake is not applied when the throttle is open?
