RWD Models

NOTE: Lock-in accuracy will be affected by engine being out of tune, adverse power-to-weight ratio, and improper slack in throttle control cable.
  1. If speed drops more than 2 to 3 MPH when cruise control is activated, lock-in adjusting screw should be turned counterclockwise approximately 1/4 turn for each one MPH correction required.
  2. If speed increases more than 2 to 3 MPH, turn screw clockwise approximately 1/4 turn for each one MPH correction required. If screw is loose, stake side of servo housing adjacent to screw to ensure a snug fit. See Fig 1 .
CAUTION: Screw should never be turned more than 2 turns in either direction or damage to servo unit may occur.
