Digital Trim Operation; Mechanical Atl Adjustment - FUTABA 4PM Short Manual

Digital Trim Operation

(Initial settings: DT1: Steering trim, DT2: Throttle trim, DT3: Channel 3, DT4: Steering D/R, DT5: ATL-Brake rate)
Operating by the trim: Push the trim lever to the left or right (up or down). The current
position is displayed on the LCD screen.
DT2
• Each step is indicated by a tone.
• When the trim exceeds the maximum trim adjustment range, the
beep will change and the servo will not move any farther.
• Steering D/R: The steering left and right servo travels are ad-
justed simultaneously.
• ATL: Decreases the set value when the braking effect is strong
and increases the set value when the braking effect is weak.
Steering And Throttle Trim Operation
With the center trim feature, trim adjustments have no
effect on the maximum servo travel. This prevents the
linkages from binding when adjustments are made.

Mechanical ATL Adjustment

Make this adjustment when you want to decrease the stroke of the brake (back) side of
the throttle trigger to your preferences.
Adjustment
1
Using a 1.5 mm hex wrench, adjust the trigger
brake (reverse) stroke. (The screw moves the
throttle trigger stopper.)
• When the screw is turned clockwise, the stroke becomes narrow-
er. Adjust the stroke while watching the screw.
Note:
Once you have changed the mechanical stroke on the brake side, be sure to adjust
the scale of the throttle channel accordingly by using the " Adjuster Function " (page
71).
Due to this change, you also need to adjust in most cases the travel of the throttle
servo by using " End Point Adjuster " .
