Model Airplane News readers are an innovative bunch, and they’re always coming up with ways to make their models better while saving time and money. Here are two workshop secrets for ensuring secure servos, every time!
Secure servo connections
When you install servos in a wing or fuselage and use long servo extension leads, the connector between the two can come lose during flight due to vibration! A simple safeguard is to slip a length of heat-shrink tubing over the connectors and apply heat with a hot air covering gun. This will make a secure connection that’s easy to remove with a sharp X-Acto knife later on.
Servo Tape Tips
A friend of mine lost his plane recently because his elevator servo came loose during flight. The servo tape came loose! When I use double-side foam servo tape (I use 3M attachment tape,) I always clean the servo case with some rubbing alcohol and then apply some clear tape to the case before applying the foam tape. For a proper bond, I also make sure the surface I stick the servo to is also clean. If your servo case is dirty and has left-over foam tape adhesive in it, be sure to clean it before reinstalling the servo. I have found the “Crayon Away” (available at Wal-Mart,) works great for removing that leftover tape residue.
