These HyperFlight CNC cut ply servo frames make fitting a Ripmax SD150 servo or a Dymond D60 servo to a molded wing very easy. No thickness is added to the installation, and the servo is mounted securely, yet can be removed easily if required.

Two servo frames supplied in the pack.

How To Mount Wing Servos Using Ply Frames

1. Glue a strip of 3mm (or 1/8”) balsa to the leading edge of the mount (width dependant on the distance the mount is likely to be behind the main spar).
2. Place the mount with the servo in-situ in the wing and abut it against the rear of the main spar.
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 fore 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 any epoxy in the inside of the mount which will prevent servo sitting properly in the mount.
6. Set up and adjust servo control rods as required. When satisfied glue servo in position using silicon / bath sealer and allow to set overnight.

To remove servo gently lever out with a suitable small screwdriver, allowing time for the sealer to break its bond between the servo and the wing.

Do not epoxy the mount in place with the servo in-situ for two reasons. A) It gets in the way when trying to place the mount. B) It introduces side loads which have a tendency to move the mount out of position whilst the epoxy is setting.

To minimise control surface slop the servo must be mounted as rigidly as possible. In molded wings this is greatly assisted by bonding the servo to the bottom wing surface, using a suitably shaped wooden block. Similarly attaching false ribs to the inner and outer edges of the servo bay will mechanically connect the upper and lower wing skins, increasing rigidity.

Ply mounting frame for a Ripmax SD150 servo

This servo wing mounting frame is very accurately CNC cut and well finished in 3mm ply so that the servo is an accurate and tight fit in the frame. The frame adds little weight to the installation and certainly does not add any thickness to the mounted servo. As provided, the servo can't be screwed directly to the frame, unless you adapt the plastic mounting lugs provided with the servo. However, I glued two small 5mm thick blocks of hardwood to the frames and screwed the servo into the blocks - which has worked well, without adding any additional thickness to a tight wing installation. Overall I was very happy with product and the very prompt delivery of the items.

Ripmax SD150 frame

Substantial and well-made frames which are an excellent fit on the servo, well packed and delivered quickly.

But in the event I didn't use them (my stupidity - nothing wrong with the product). Bought to install wing servos in a 2m glider which came with smaller U-shaped frames with a small hole each end. Instructions showed these used with plastic clips. Because there were no clips in the kit in the kit I ordered the frames from Hyperflight. In fact the clips come with the SD150 itself and used with the U-shaped frames in the kit allow installation in a tighter space.

These take the pain out of servo installation, making accurate secure placement simple.I fix them with Gorilla glue with the servo in place ,the servo wrapped in polyprop film to prevent it getting stuck.Small birch ply blocks are then fitted against the servo lugs. A thin strip of 1/32 ply then goes across the servo held by screws. Perhaps not the most elegant but its rock solid and in the event of servo death they can be easily replaced .
These frames also fit some Hitec servos with only a tiny bit of trimming.
The foaming action of the Gorilla glue fills any voids and spreads the loading to the wing. Simples.
