Update: Savage Carbon - STOL Realism Mod (v2.10 / Dec 27, 2022)


A more powerful, stronger and meaner Savage Cub, retrofitted to be a true bush machine.


The Savage Carbon is a custom backcountry aircraft built to be a versatile high performance stick and rudder bush machine. She excels at STOL yet flies with XCubs.

She’s a load of fun. She’s also a fully featured and well-tested study level bush bird.





Water Skiing is a first in MSFS in the Savage Carbon. However, water related physics in MSFS are currently far from complete or perfect and things can occasionally get bumpy. Water spray is not in the sim yet, and neither are wakes. But … buoyancy and water hardness with speed are all you need for now, and the Savage Carbon has got you covered!

While practicing your mermaid skills, I would first of all highly recommend to set CRASH DAMAGE to OFF (in the Assistance menu). Especially when rolling onto the beach…the sim often just “crashes” you without a real reason, no matter how soft your roll onto land.

To practice gentle water landings, try this:

  • Approach a body of water and deploy flap 1 around 60kts.
  • Flap 2 around 45kts. Trim.
  • Ease the throttle another 100RPM just prior to a soft touchdown.
  • Gently roll onto the beach under an angle at 30kts, flaps 0, full stick back pressure and brake.

Finally, a great place to get your feet wet (or not) is in Sitka (PASI). The runway is practically in the water.

DISCLAIMER: DO NOT ATTEMPT THIS IN REAL LIFE. Just because you get it to work in the sim does not mean it works in your plane. Water skiing is extremely dangerous.


The Savage Carbon will install as a new plane, appearing next to the Savage Cub. 19 Liveries are included.

1. Download the Savage Carbon


2. Drag into the Community Folder

  1. First of all make sure the default MSFS Savage Cub is installed, this mod depends on it
  2. Delete older versions of the mod
  3. Extract the ZIP file
  4. Drag the folder named gotgravel-savage-carbon directly into the Community folder
  5. Restart the sim
  6. You’ll find the Savage Carbon 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


The Backcountry Experience

Bush machines are extreme machines, often pushed to the edge of their performance envelopes. Always wanted to fly one? Get the Savage Carbon for the most authentic STOL experience possible…short of flying the real thing.

The STOL stuff:

  • 29" Alaskan Bushwheels.
  • 165HP Edge Performance engine.
  • Water skiing.
  • 82" Whirlwind GA-200L-STOL propeller.
  • King Shock absorbers and upgraded suspension.
  • Powerful disc brakes.
  • Execute the Knife Edge aerobatic move.
  • A 3rd monster flap (60 degrees!) so you can fly slower approaches, with higher sink rates, giving you 15ft landing bragging rights.
  • Flaps move faster so you can pump them for short take offs and retract them at touchdown for maximum braking power.
  • Flaperons…using 20% aileron as flaps
  • Ground handling is what you would expect from a purpose-built backcountry aircraft: Lift your tail, propwash left and right, brake on a dime.
  • Vortex Generators on wing and tail are accurately simulated, delaying stalls and enabling those slow STOL approaches.

Other features (non exhaustive):

  • Full CFD (Computational Fluid Dynamics)
  • 20 Custom Liveries.
  • Flight model parameters like parasite drag, induced drag, flap drag and lift, moment of inertia along all axis, P-factor, propwash, torque, weather vaning, gyroscopic precession and more have been tuned to recreate that unique bush plane thrill.
  • 100% Custom lights with powerful landing light.
  • Enhanced Night VFR lights inside the cockpit.
  • Rearward facing landing light (“Torch” switch) for team leads so others can follow easily.
  • Parking brakes added (previous choke lever).
  • Cabin Heat defrosts windshield.
  • The CG has been completely reworked by correctly positioning all simulated masses in 3D space, resulting in a stable and natural feeling aircraft.

It took well over 200 hours of research and test flights to tune all aspects of the model. Performance is frequently evaluated by 2 seasoned pilots with experience in similar planes.


This Savage Cub to Savage Carbon conversion mod is free and always will be, but if you enjoy it and feel you want to contribute towards this ongoing project it will always be appreciated.





The Savage has no autopilot installed (you will find none in the cockpit), but for your convenience I did tune and test the setup for a relaxed experience. However, it is disabled by default.

To enable, follow the 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.

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

Note on the “Generation 2” Flight Model. I have been working hard on another aircraft, the aerobatic Gee Bee R3. Developing this has certainly pushed the limits of what the MSFS Flight Model can do and has taught me more than Carbon, Grravel and Vertigo combined. Hence I have redeveloped Carbon’s Flight Model entirely from scratch putting in all the lessons learned so far. Enjoy the new flight experience!

I don’t know if it’s realistic, but i love it. Nice low speed landings and enough power to be fast high in the sky. :wink:


I have been flying this homesick angel for about an hour now. It has become my go to for Bush flying. Thanks, awesome aerie!!


Thanks guys! Very glad you’re all enjoying this bush machine :sunglasses:

Just a heads-up, gonna be working on the brakes a little in a couple of hours, so expect update 1.0.2 today. There have been a couple of reports that it is too easy to get a nose-over on some approaches, so will be fixing that. Perhaps move the mains forward a few more inches or reduce brake power just a little. Maybe a bit of both.
Secondly I will consider installing handbrakes. Did not come with the original Savage but that does not stop me from upgrading the Carbon :wink:

A selection of liveries are also in the pipeline, but that will be later this week most likely. In any case, development is ongoing and I’m hearing all your feedback.



Freakin LOVE it!!! If there is a way you could do this kind of mod with the shock ultra it would be awesome!!! I see on their website you can run the 915is in the shock ultra , im curious to see the performance with that! Until then , the carbon is my new go to for bush flying! Many thanks for your hard work!!


How realistic is this fictional mod? Good question!

I would say very. The engine is a highly accurate simulation of the Rotax 915iS. For starters. The plane’s weight has only be reduced by 10% (empty weight from 650 to 585lbs, or 265kg). Not unrealistic given that carbon fiber is about 45% lighter than regular aluminum. The CG calculations are much more accurate than the default Savage Cub too, and so are many other parameters.

Move the mains forward so you can brake harder? Entirely what is done in the real STOL world too. Have done my homework here :wink:


Upgrade the Shock Ultra with the 915? Would love to seriously. However all premium aircraft are locked when it comes to modding, so can’t touch that (for now…here is hoping the modding community will gain access to fixing premium planes in the future).

You sound like a virtual Mike Patey. Look at the performance of the Wilga mods he has done. Power to weight ratio is a marvellous thing.:+1:


Can only take that as a compliment. But got to admit, watched most of his videos. Totally amazing what he does. Now following all his work on his Scrappy bush plane…looks like it’s getting closer and closer to first flight :slight_smile:

You can trust mike to max thrust. No small engines for his planes!

In the mean time…handbrakes have been installed in the Savage Carbon! Coming in the next update :wink:

Great. No glass panels or nav equipment. Much VFR fun to be had.!


Cool. Fun stuff. You community modders are making the sim interesting.

Thanks for this mod, nothing like a little more power. Notice the nav and strobe lights aren’t appearing from some angles. Wasn’t quick enough to catch the stobe lights but they seem to use the same logic as the associated nav light.

Yeah there’s a bit of a bug with the newly installed nav and strobe lights directions, have yet to dive into that. They weirdly enough seem to follow a fixed heading … not relative to the plane but to the world.
