Steering Dual Rates Setup INC

ST.DR DEC

ST.D/R SW

•DEFINITION: Steering Dual Rate (ST. DR): Is the adjustment that allows the dual rate value (maximum servo travel) to be increased (INC) or decreased(DEC) with in a range of 0% to 100% of the steering servo. This functions very useful in a race conditions as it allows you to tailor the steering radius and sensitivity for the current track conditions.

•ADJUSTMENT: 1.Press and hold the “INC” (Increase) button until the LED on the “ST.DR” blinking green into a blinking red indicating maximum turning radius or value of 100%. 2.Press and hold the “DEC” (Decrease) button until the LED on the ‘ST.DR” start blinking green and goes to a blinking red LED indicating minimum turning radius or value 0%.

•Finding Neutral position on the Steering To find the center or neutral position on your transmitter, turn it on. Push the “ST-TRIM” left and notice the “ST-DR” will start flashing Green then slowly turn to a flashing Red hold it there until you see a steady flashing Red, now you know you are at the end of left side trim. Now to find the center or neutral position of the steering trim push the “ST-TRIM” to the right and hold it, you will notice that the “ST-DR” LED will start flashing Green hold it their until you see that it will turn RED let go, now you are at center or neutral position, if you go past the RED light it will start flashing GREEN again you are now off center or neutral and going toward the right. •Racer Tip Always check and be sure the servo is at it neutral position before installing a servo. Adjust the servo horn hole position and linkage so that both are parallel. When a servo saver is used, place it as close to center position as possible. Be sure the steering trim on the transmitter is at the neutral position. •Trim Operation and Maximum Travel. Changing the trim can effect the overall settings, when adjustments are made with the trims, please recheck your installation for maximum servo travel. When Trim movement goes to extremes and your vehicle will not go straight. That means if you make a lot of trim movement to get a servo to the neutral position, please reposition the servo horn or servo saver on the servo and inspect your linkage installation.
