Removing the Parts from the Panel
The PVC parts need to be carefully cut out of the panel. A thin, flat blade exacto knife will be very helpful. Simply cut through the tabs to remove the parts.
Important!
DO NOT overtighten screws on the PVC parts! The PVC will compress and will become weaker as a result.
Preparation
Remove the nylon servo horn from each servo and replace with a metal servo horn. Be sure to keep it in the same orientation.
Attach a ball bearing to a Multi-purpose bracket as shown. See the diagram below for detailed information. Make two of these.
