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 a few 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.
