We advise using the included grommets when installing this servo.
When installing the K-Power DM4000 as a throttle servo in the Losi DBXL,
you have to raise the linkage lever by putting two M4 washers between lever and pedestal to ensure the lever will clear the servo.

In addition, the servo can be installed without rubber grommets (like the stock servo).

After installation, servo travel must be re-adjusted.

  • 1 x 4 sided servo arm. 55 mm total length
  • 1 x 50 mm long single sided servo arm
  • 4 x guide sleeves
  • 4 x rubber grommets
  • 4 x mounting screws

RC-CAR-ONLINE did a nice demo of these servos under human load!
