|Wing Servo Mounts|
These 4mm ply CNC cut servo mounts are designed for use in the wings of sport moulded gliders. They are not designed for high stress environments such as high speed dynamic soaring or record breaking speed attempts where it is advisable to add additional support to the servo output shaft. They are designed to be a snug fit around the servo to stop it moving under load. The servo mount is epoxied in the wing whilst the servo is held in place with a silicone adhesive. Mounting the servo this way allows it to be removed relatively easily with minimal if any damage to the servo.
1. Superglue a strip of 3mm balsa to the leading edge of the mount (width dependant on the distance the mount is likely to be behind the main spar). The purpose of the balsa strip is to act as a locator when gluing mount in place.
2. Place the mount with the servo in-situ in the wing and abut it against the rear of the mainspar.
3. Slide the mount sideways until it is in the correct position laterally and determine how much the width of the 3mm balsa needs to be adjusted for the mount to be in the correct position for and aft.
4. Trim balsa to size. Reposition servo mount in wing and when happy with position draw a pencil line around the outside of the mount.
5. Remove servo from mount and epoxy mount into wing taking care not to get a fillet of epoxy in the inside of the mount which will prevent servo sitting properly in the mount.
6. Set up and adjust servo control rods etc. as required. When satisfied glue servo in position using silicon / bath sealer and allow to set overnight.
7. To remove servo gentle lever servo out, allowing time for the sealer to break its bond with servo/wing via the outshaft and servo lugs using suitable small screwdrivers.
It is important to NOT too epoxy the mount in place with the servo in-situ for two reasons, one it gets in the way when trying to place the mount in the correct postion and secondly introduces side loads which have a tendency to move the mount out of position whilst the epoxy is setting.
