Wltoys K969 K979 K989 K999 1/28 Upgraded 5g Metal Gear Steering Servo K989-58 RC Car Vehicles Parts
A part of the review has been auto-translated.
This servo is a direct replacement for the stock WLToys K969/K989 steering servo. It's a higher quality servo than the stock one, it is noticably smoother. It fits into the stock servo mount perfectly. You will want to remove the mounting bracket on the long side of the servo (see photos) so it does not interfere with the body. It comes with only one choice of servo arm, which is the one I have installed in the photos. The arm is longer than the stock one, which is good and bad. Good because it gives a steeper steering angle than stock. Bad because the top plate (removed in photos) interferes with the longer arm's articulation. DIY RC has a video on how to make a custom CF top plate to accommodate a longer servo arm. You could also just cut the arm shorter and use the stock top plate. Overall this is a very good upgrade part.
All right.
