Expert Overview

The updated Grumman J2F Duck mod for Microsoft Flight Simulator masterfully merges its 1930s amphibious heritage with a fully modernized cockpit framework. Its refined flight model, streamlined engine configuration, and enhanced textures provide an immersive biplane experience that captures the spirit of both mid-century military aviation and contemporary sim technology.

Featuring three key variants and a total of 15 liveries (including the famous movie adaptation), this freeware release offers diverse operational roles and visual styles. In my experience testing it, highlights include vigilant attention to detail in aerodynamics, cockpit instrumentation, and weather effects, making this a solid choice for those seeking a robust amphibian adventure in MSFS.

The Grumman J2F Duck for Microsoft Flight Simulator offers an authentic biplane amphibian experience, blending historical accuracy with modern cockpit capabilities. Originally designed in the mid-1930s, this single-engine military amphibious craft provided crucial support during World War II. Now, thanks to flyndive and the original work by Paul Domingue, you can operate this fully native MSFS rendition on both Microsoft Flight Simulator 2020 and 2024.

Evolution of a Classic Biplane

The Grumman J2F "Duck" flying over water after taking off from water displayed in the latest Microsoft Flight Simulator 2024 edition.The real-world J2F Duck served across multiple branches of the U.S. armed forces. It featured a radial engine, large floats (built into the fuselage), and a robust airframe for challenging water landings. In its MSFS form, the entire model has been redistributed as freeware, with explicit permission from Paul Domingue to bring his FSX creation into the modern simulator environment. Extensive updates include advanced modeling, texture conversions, refined animations, and improvements to the engine configuration and flight dynamics.

Noteworthy Technical Enhancements

  • Flight Model Refinements: Adjusted aerodynamic profiles and engine performance, ensuring authentic handling in diverse conditions.
  • Systems and Lighting: Updated cockpit instrumentation, lighting cues, and operational elements such as radios and munitions.
  • Sound and Special Effects: Enhanced audio layers and weather effects to reinforce immersion.
  • Native Texture Support: Optimized textures for MSFS, preserving optimal quality and performance.

Diverse Variants and Unique Liveries

This package provides three distinct Duck variants: J2F4, J2F5, and J2F6, each reflecting notable design changes from the real aircraft’s evolution. You will find 15 total paint schemes, including the special rendition seen in the movie “Murphy’s War.” That particular variant omits the engine cowling, canopies, and radome, replicating the on-screen appearance with high fidelity.

Future Paint Kit Availability

A dedicated paint kit is in development for those seeking to craft custom liveries, and it will be distributed separately once completed.

Planned Enhancements

Following extensive user feedback, additional tweaks are proposed for future versions, including refined engine cowling geometry on the J2F4, camera position adjustments, and more convenient default parking brake settings. Updates will also optimize airspeed and fuel readouts on the HUD, ensuring a smoother experience.

Recent Update Highlights (v1.2)

  • Collision Mesh for MSFS 2024: A full-body mesh prevents avatar walk-through in the new platform build.
  • Model Consolidation: Now displayed as a single aircraft entry with selectable variants and liveries in MSFS 2024.
  • VR Panel Collisions: Improved panel collision meshes heighten realism in virtual reality.
  • Tool-Tip Integration: Fuel selector switch now includes interactive prompts.
  • Minor Mesh Pruning: Eliminated duplicated brackets in the wheel well to address visual flickering.
  • Pilot and co-pilot representations in MSFS 2024 remain limited by a current simulator bug.

Additional Corrections (v1.1)

  • Windshield rain direction fixed on all related glass surfaces.
  • Updated throttle, mixture, and prop functionality to mirror realistic cockpit operations.
  • Removed extraneous engine cowling elements from the J2F6 variant.
  • Tweaked textures and addressed overlapping hatches in the J2F4 model.

Installation and Folder Structure

Inside the ZIP file, you will find the aircraft folder, a brief readme, plus the Grumman J2F Operation Manual. To begin, drop the folder named “flyndive-pd-aircraft-msfs-grumman-duck” (or similarly titled) into your simulator’s Community folder. When upgrading in the future, remove the previous installment before placing the new one to avoid conflicts.

How to install this mod

MSFS add-on
  1. Extract the downloaded archive

    Use 7-Zip (free) or WinRAR to extract the ZIP to a temporary folder. Don't install while still zipped — the simulator can't read inside ZIP files.
  2. Locate your MSFS Community folder

    All MSFS add-ons live in the Community folder. Microsoft Store / Game Pass version: %LOCALAPPDATA%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\Packages\Community\. Steam version: %APPDATA%\Microsoft Flight Simulator\Packages\Community\. Tip: enable Developer Mode in MSFS to see your exact Community folder path.
  3. Copy the package into Community

    Drag the extracted folder into your Community folder. Most MSFS add-ons follow this pattern.
  4. Restart MSFS

    Close MSFS completely and relaunch. The new content appears in the Content Manager, on the World Map, or in the aircraft/livery selector.
  5. Always read the included readme

    Every mod ships with a readme.txt or README file. It tells you exactly where files go, what dependencies are needed, and any quirks specific to this add-on.

    Another wonder not to be missed.

    An impressive work that manages to create the real sensation of flying this mythical hydroplane that can not help but remind us of those unforgettable sequences of the famous movie “Murphy's War”.

    Very detailed instruments, and surprisingly good effects in the splashdowns!
