SERVO MOUNT CONSTRUCTION
By Roy Vaillancourt 411

Many people have many different ways of mounting servos. Each has its own advantages and disadvantages. Some things to be considered in a servo mount are: the degree of complexity, ease to fabricate, size or compactness and, probably the most important feature, rigidity.

Fabricating a servo tray for fuselage installations is fairly simple. Everyone has their own pet method. This is usually one area where space is not a problem when it comes to Big Birds, so I won't even attempt to start to discuss the various methods.

What I would like to present is a simple, yet very effective servo mount for use in the wing where the servo must lay on its side. This is usually done in order for the servo to fit inside the airfoil. Construction is very simple and I'm sure the following drawings are self explanatory.

A mount of this type allows for easy removal of any servo for servicing. If all your servo mounts are identical (ex. flaps and ailerons) it also provides for interchangeability. If you wish to install a different servo (either bigger or smaller) just make a new mount. No need to chop up the wing!

Assemble all parts using 15 min. epoxy, keep all parts square to the base. After epoxy cures sand back of base smooth to provide a flat surface.
