MSFS2020 - Savage Carbon - STOL Realism Mod - V.1.0.5



A lighter, faster and stronger Savage Cub with a 141HP Rotax 915iS powerplant.

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 awfully close to a study level aircraft.

The Experience

Bush machines are extreme machines, often pushed to the edge of their performance envelopes. To give you the most authentic STOL experience possible, we knew from the start that the flight model had to be pushed to extremes as well.

To this end it took well over 150 hours of research, engineering and test flights to tune all aspects of the model to satisfaction, always supported by actual Zlin Aviation POH data and Rotax engine specifications. Performance is frequently evaluated by 2 seasoned pilots with experience in similar planes.

Some of the highlights:

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 finely tuned.

The CG has been reworked by correctly positioning all simulated masses in 3D space, resulting into a stable aircraft and a natural feeling flight experience.

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.

Aerodynamic pressure on control surfaces at high speeds is correctly represented giving you full control of the aircraft at all velocities.

More STOL stuff:

A 3rd monster flap setting has been added (60 degrees!) so you can fly slower approaches, with higher sink rates, giving you 15ft landing bragging rights.

The mains were moved forward a bit so you can (almost) safely prime the brakes before touch down.

Flaps move faster so you can pump them for short take offs and retract them at touchdown for maximum braking power.

The Airframe

The Savage Carbon’s airframe is constructed of a tough carbon fiber skeleton, making her about 10% lighter than a Savage Cub while enabling her to sustain higher g-forces.

The Engine

Powered by the latest turbo charged and injected Rotax 915iS, this reliable 141HP workhorse is responsible for giving the Savage Carbon an unmatched power to weight ratio.

All 3 engine gauges - oil temperature, oil pressure and CHT temperature - are accurately simulated as well providing an immersive flight experience.

So yes, you do need to warm up your engine for 2 minutes or so, and the choke is

needed on a cold day.

The Prop

A larger 2 meter wooden fixed pitch propeller was installed converting all that power into plenty of thrust.

The Liveries

Comes with 13 custom designed liveries including 2 popular historic D-Day designs (USAF and RAF). All liveries come with red lambskin seats.

CHANGE LOG

Changelog v1.0.5 (Nov 19, 2020):

3rd monster flap added (60deg!) to enable steeper high-sink rate approaches…and even slower ones

Faster flap change speed of half a second…commonly seen in STOL work

Auxiliary fuel tanks installed in the back seat

Prop shutdown a little slower to sync with shutdown sound exactly

Rotating prop 3x more transparent to match real-life looks

Increased maximum gross weight from 1111lbs to 1150lbs

Much easier to trim elevator

Faster roll at lower speeds

More tips added to the loading screen

Changelog v1.0.4 (Nov 13, 2020):

Added 2 more liveries (D-Day USAF and D-Day RAF), bringing the total to 13.

New and improved Rotax 915iS with much more accurate power curves

Further refined engine gauges (Oil temp, Oil press, CHT temp)

Simulated aerodynamic back pressure on control surfaces at higher velocities

Dramatically improved STOL realism and control

Excellent ground handling, can throw your tail left and right with just propwash

Fixed: much reduced nose-up attitude upon flap deployment

Much more realistic flight model overall

Changelog v1.0.3 (Nov 6, 2020):

Added 5 more liveries (purple, teal, black, batman and zebra), bringing the total to 11

More realistic oil temperature and pressure gauge simulation

Much improved ground handling

Much improved CG (even harder to nose-dip now…unless you don’t apply stick back pressure)

More powerful pneumatic brakes

Ground effect (added)

Gyroscopic precession effect (stronger effect)

P-Factor (stronger effect)

Torque (stronger effect)

Weather Vaning (added)

Adverse Yaw (added…but FS2020 does not do this very well yet)

Propwash (stronger effect)

Changelog v1.0.2 (Nov 1, 2020):

Added 5 new liveries to the default white: red, orange, yellow, green and blue

Added handbrake

Adjusted brakes (it’s now harder to nose-dip)

Increased fuel capacity by 50%

Improved flight model

ICAO Type Designator set to SVCB (seen in multiplayer labels)

Changelog v1.0.1 (Oct 28, 2020):
