Himoto MXB-3 Throttle/Brake Servo Linkage Fix
My new Himoto Racing MXB-3 buggy had a throttle/brake servo binding issue that prevented use of the brakes. Inspection of the area showed that the binding was caused by a slider installed on the portion of the servo that has a linkage connecting to the carburetor. From the illustrations provided by Himoto, this slider is installed on the top of the servo - as mine was.
Unfortunately due to the geometry involved with the servo and motor/carburetor mounts, this is incorrect and leads to binding. The problem is that the slider can only rotate in the horizontal plane through the screw that connects it to the servo arm - but it can not be aligned vertically with the carburetor linkage. This constraint leads to binding when the brake is applied, and as a result no braking force is produced.
The fix is simple - reinstall the linkage under the servo. Now it can be aligned vertically with the linkage end at the carburetor, and is free to rotate horizontally as intended. When the brake is applied, it slides freely and allows the brake to engage. Please reference the image below if you are having binding issues with your RC car.
