Hirobo servo frame for Eagle-series helicopter models

The Hirobo HI0404686 servo frame is a replacement mount intended to secure a standard servo within the Eagle family of model helicopters. It locates the servo accurately so control linkages align and operate without binding.

Compatibility: designed for Eagle, Freya, EX and SX series helicopters. Before fitting, compare the frame's mounting pattern to your airframe and confirm available clearance for the servo horn and wiring.

Installation notes: attach the frame using the airframe's original screws where possible, or substitute matching threaded fasteners of the correct length. Check servo orientation, route leads clear of moving parts, and verify that linkages travel freely across their full range.

Practical fit guidance: confirming hole spacing and vertical clearance prior to installation avoids the need for modifications and keeps surrounding components functioning as intended once the servo is secured.

Fit the HI0404686 frame to return correct servo mounting and maintain reliable control geometry across compatible Hirobo Eagle models.

What should I check for compatibility before buying?

Measure the servo bay mounting hole spacing and the vertical clearance for the servo horn and leads. Confirm these dimensions match the frame to avoid interference once installed.

Is this frame interchangeable between Eagle and Freya series?

It is listed for use across Eagle, Freya, EX and SX series, but small differences between airframe revisions mean you should verify the fitment details on your specific model before installation.

Will I need to alter linkages after fitting?

You may need to adjust linkage lengths or horn positions to re-establish neutral geometry after fitting; set the servo to centre and then adjust linkages to remove any pre-load or binding.

What screws should I use if originals are missing?

Use screws matching the original thread pitch and appropriate length—avoid screws that bottom out or protrude into internal components. Stainless or plated options are suitable for longevity.

How can I confirm there is no binding after install?

With the transmitter trims neutral, power up and perform slow control sweeps at low throttle to ensure full travel without resistance, then recheck horn and linkage positions.

Should I recheck mounting after a few flights?

Yes. Inspect screw torque and linkage alignment after initial flights and following any rough landings to ensure the frame remains secure and control geometry stable.
