MMM punch control.....
 

Running the e-revo brushless , I just purchased a feild link card to adjust on the go and still be able to use castle link now my question regarding the punch control setting when the card is all plugged in and I go to punch control there's no read light does this mean that the more I adjust it the softer hard accelerations will be.
Thanks matty

Let me just make sure I understand your question.. You're wondering if the higher the punch control percentage, the softer your E-Revo will accelerate off the line when you go from a stand still to WOT (wide open throttle, or full throttle)??

If that's the case then the answer is the opposite. The lower the percentage the softer your E-Revo will accelerate off the line when you "put the pedal to the floor" so to speak.. Putting the punch control setting to 100% will put as much power to the wheels as practically possible when you hit the throttle. Running 6s LiPo on a MMM with punch control at 100% I do standing backflips with my E-Revo, meaning rather than doing a wheelie it'll just do a complete backflip and land on the wheels.

A side note and a word of caution on that, I wouldn't recommend doing these 'torquing acrobatics' unless you have a full metal drive system, meaning metal everything from the motor pinion to the tips of the wheels. It can handle a lot, but I drive quite aggressively :flaming: with it so I like to play things decently safe in terms of the frequency of replacing parts. :D

Torque control
 

FYI, you can also use torque control with the Castle Link settings. Personally, I prefer torque control over punch control. Punch control limits your power during acceleration (it limits rapid changes to throttle), and torque control limits the total current, and hence torque, going to your motor. Torque control is better IMO b/c it's smoother, i.e., it does not have that split second dead spot after hard brake and then back to throttle. Also, I have read that the ESC runs cooler as well.

#6 is about punch control

or here it is for those who are too lazy to look at the link :)

This setting controls how much the ESC limits the current draw of the motor, in order to maintain control of the car under acceleration from a dead stop, or coming out of a corner. The higher the setting, the "calmer" the acceleration will be from a stans-still, or from low speed to high. This also helps protect tires and drivetrains during bashing, by putting them under less stress from the motor. Remember, an electric system is only as good as the batteries powering it, and the system cannot make up for a lack of performance from the packs/connectors. While running in the very low limiting, or with the limiting off, punch & acceleration power are at the mercy of the batteries; the better the pack, the more off-the-line power you'll have available.
