EPA? Whats that?... Sorry dont mean to sound stupid... Just trying to understand how it works.

EPA is End Point Adjustment, which is typically set on your radio.
There is an EPA on your throttle and an EPA on your steering.
Normal uses of the throttle EPA is to limit top speed or limit the amount of braking. For example, say your truck is too fast at full throttle (I know, it's NEVER too fast :003: ) but it's a good controllable speed at about 3/4 throttle. If you set your throttle high end EPA to 75 (assuming it's 0-100), your full throttle will now be only 75% of the total. The same idea can be used for braking - if you're used to pushing full brake and it's too much (locks up, etc...) you can adjust your brake EPA down to a level where it brakes to your liking.
The most common ( and VERY important for servo health) use of steering EPA is to make sure your steering servo isn't fighting against the steering throw lock in your vehicle. One good way to set your steering end points is to put your vehicle on a stand, then turn full in one direction. Adjust the EPA for that direction down until the wheels begin to turn back, then adjust step by step until you can turn the wheels fully in that direction without straining your servo against the steering throw lock. Then do the same for the other side. In my experience, most vehicles will have you setting your EPA for steering somewhere between 60 and 80 (based on a 0-100 setting).

Let me know if that helps out with your EPA question. If you want any more info, I'll be happy to help.

Thanks for the explanation Batfish. Very thorough.

I get the EPA thing now, but if it was that, wouldn't it also effect top speed by just limiting the throtle?

I know in the warior and the mamba controlers there is a timing adjustment you can change if you use the programing cable. I know this has a huge efect on the heat in the motor and the controler along with efecting the torque and slightly efecting speed. Is the ''torue'' setting on the Quark the same thing as the timing setting on the others?
