The Savage Grravel is a monster truck in the skies, heavily inspired by and paying homage to Mike Patey’s Scrappy. She’s got a converted Ford Mustang 230HP 2.5L V6 engine (+90HP with NOS), a 4 bladed 6 foot Whirlwind STOL optimized prop and 35" Alaskan Bushwheels.

Grravel is an absurd beast of a STOL machine, essentially a monster truck version of the Savage Carbon. She's heavier, more powerful, and just...more extreme. She comes with 5 exclusive liveries.

  • 230HP 2.5L V6 “Ford Mustang” engine, adapted for use in a cub.
  • 35" Alaskan Bushwheels.
  • 4 Bladed 6 foot prop for out-of-this-world acceleration and climbrate.
  • NOS injection (about 100HP) for up to 4.5 minutes 
  • 2 x 27 Gallon tanks to feed the thirsty V6.
  • 100% Custom lights with powerful landing light.
  • Enhanced Night VFR lights inside the cockpit.
  • Rearward facing landing light (“Toggle Recognition Light” keybind) for team leads so others can follow easily.
  • Reinforced structure, higher MTOW.
  • Comfortably cruises at 125kts, punch it to hit 150 in seconds.
  • Sustained climb rate of 4000fpm.
  • Execute the Knife Edge aerobatic move.
  • 800nm range at sea level at 4200RPM.
  • Wider wheelbase.
  • King Shock absorbers and upgraded suspension.
  • Powerful disc brakes.
  • A 3rd monster flap (60 degrees!) so you can fly slower approaches, with higher sink rates, giving you 50ft landing bragging rights.
  • Superb ground handling.
  • Vortex Generators on wing and tail are accurately simulated, delaying stalls and enabling those slow STOL approaches.
  • Windshield de-icing (use the cabinheat lever).
  • Modern Prop Physics and Computational Fluid Dynamics (CFD)

Grravel is free and always will be, but if you enjoy this beast and feel you want to contribute towards this ongoing project it will always be appreciated.


  • First of all make sure the default MSFS Savage Cub is installed, this mod depends on it.
  • Delete older versions of the Savage Grravel mod, if any.
  • Extract the ZIP file.
  • Drag the folder named gotgravel-savage-grravel directly into the Community folder.
  • Restart the sim.
  • You'll find Grravel in your hangar all the way to the right near the default MSFS Savage Cub.

If done correctly, your folder structure should look like this:


How to find the Community folder?

  • If you changed the default location of packages, it’s the simplest because you should find a Community sub folder in it.
  • For Steam, it should be located in C:\Users\ [Computer Name]\ AppData\ Local\ Packages\  Microsoft.FlightDashboard_8wekyb3d8bbwe\ LocalCache\ Packages\ Community
  • For Windows Store C:\Users\ [Computer Name]\ AppData\ Local\ Packages\ Microsoft.FlightSimulator_8wekyb3d8bbwe\ LocalCache\ Packages\ Community



I have multiple threads on various flight sim forums and websites (including this one) and it is not possible for me to respond to queries on all of them.

Support is therefor exclusively provided from the Got Gravel Discord Server ( through the "Got Support" channel inside the "Got Friends" category.


Need even more power? Grravel now comes with NOS equipped giving you up to 4.5 minutes of additional 90HP. Use the new NOS gauge to see how much supply you have left (1200psi is full, 800psi is empty). To engage either toggle the NOS switch in the cockpit or use the MSFS “War Emergency Power” keybind (recommended) for instant gratification.



The “Torch” is a unique rearward facing landing light, similar to what was installed on Draco. When turned on (use the “Toggle Recognition Light” keybind), it will be easy for others to spot you from behind. Great if you are a team lead for a group flight!



Choose your panel! You will find 5 panels to choose from in the swap-your-panel folder.


Choose your ASI face to be white or black! Select them from the swap-your-asi folder.


Grravel has no autopilot installed (you will find none in the cockpit), but for your convenience I did tune and test the configuration for a relaxed experience. However, it is disabled by default.
To enable, follow the simple instructions below. You will also need to setup and use your own keybinds for autopilot on / off state, altitude hold and heading hold if you haven't done so yet.

  • Go to your community folder
  • Go to gotgravel-savage-grravel / SimObjects / Airplanes / Asobo_Savage_Grravel
  • Open the file engines.cfg in a text editor
  • Go to the last line and change the 1 to 0 (DisableAutopilotControls = 0)
  • Restart sim if it was running


  • The Savage Grravel is an ongoing project by Got Gravel.
  • Flight testing by experienced real-life pilots avaricooper and roketJsquerl.

Altitude in the autopilot dont work...

Any chance of make an efb/tablet for this superb aircraft?

Great job thx !!!

I didn't really like this aircraft when I first got it, but that might be related to the fact that I absolutely sucked at landing taildraggers! 😁

Now I have come to appreciate this as one of the best and most fun airplanes available in MSFS. It is beautifully rendered and realized, with perfect attributes & features when, if like me you are time-poor, you just want to get in a plane and go for a fly! Awesome!

The Savage Grravel has been updated!

- Full CFD (Computational Fluid Dynamics) for an immersive flight experience

- Retuned and refined flight model

- Control stick ground roll and engine vibrations

- Gauge needle vibrations

- Overhauled cockpit lighting with individual gauge lights, pedal spots and flap lever spot

- Overhauled electrical system using actual battery and generator data

- Improved suspension (30% static compression)

- Custom thermo dynamics for Oil and CHT

It's simply.... SAVAGE

My favorite planes. In a 3-axis, triple monitor motion cockpit they feel/respond more realistically than most other planes. One question, in engine off emergency landing, the glide characteristics of the Savage Gravel seem more like a brick than what I was expecting from an aircraft with this wing configuration. Is this accurate?

I liked the Savage of the game

And now I love this one ! so funny ! Great !

Autopilot does NOT work on the plane, and is shows Autopilot=1 in the config CFG

I love all your products but my favourites are the VERTIGO and the NX Monster Cub with a Lycoming 313i.

Would it be a possibility to add Garmin avionics in your tail wheel bush planes as well? I am not fond of tail wheels, but I do want to try your products inspired by Mike Patey's innovations.

It would be quite helpful to have in-plane Garmin avionics for long bush flights instead of using the ugly map navigation windows covering a lot of screen real estate in MSFS.

Please do consider.

And THANKS A MILLION for all your generosity, kindness and time.

Just wanted to say that I'm having so much fun with this! I downloaded it a while ago but it's mostly been sitting idle in my hanger. Most of my flying lately have been airliners. But today I've spent hours in it - and it's a beast! Thanks for this mod!

It is still version 1.8.0 in manifest.json


- Added CFD (Computational Fluid Dynamics)

- Increased induced drag a little

- Reduced wheel brakes a little

Fantastic mod, love the STOL performance of this thing. A couple things I've noticed (REALLY MINOR gripes).

1) You can still see the Rotax emblem on the cylinder heads in the plane, even though it's supposed to have a Mustang V6.

2) Sustained turn performance is unrealistic, having flown a similar build myself in real life, this version in the sim simply doesn't drop any speed in tight sustained turn. This isn't accurate, so it would be cool if you lost some speed in a turn.

3) Climb performance is so good it makes the nitrous oxide feed pretty redundant. I've climbed 15k foot peaks in this thing at a sustained 2000 FPM and that shouldn't be possible above 6k feet without the nitrous. Sure, we lose a little airspeed doing this, but no more than you would lose from the change in altitude (and therefore oxygen availability for the engine).

4) The engine simply does not fail, ever, even if you drive it at max power at sea level for two hours straight. This doesn't feel realistic, but I don't know how the engine is actually tuned. It may be downrated enough that it won't fail. Still, automotive engines have a much higher failure rate than purpose built aviation powerplants, and this does not seem to be reflected by the performance of the engine in the game.

Finally, the recent sim update (April 26th, 2022) has introduced a bug where switching between online and offline mode completely freezes the simulation. The plane stops midair, and all switches cease functioning, save for the parking break and the window anti-ice (but even then, the animations don't show).

Overall, I love it, I've flown 15,872 nm in it according to Little NavMap logs. Very fun little STOL plane that you can land on a dime (if you're careful not to do a stoppie and crash the props because you went too hard on the brakes.) I give it five stars, because I sure as heck couldn't make something this good. All my criticisms are minor issues that do not take away from my enjoyment - really more just a wishlist for future updates!

Thank you, GotGravel!

as much as I love the new update, its always ctding. I cant play the game at all. ever since I installed this it basically bricked my game, I thought when I deleted the mod it would help but no it did not. now I have a non functioning copy of msfs; I use the Microsoft store version. my specs are: Intel 11600k, MSI z590 gaming edge, GeForce gtx 1660s and 2 4tb SSD's.

how do I give infinite nitrious?
