This Project took a part of my sanity forever, yet I still love it.

Instructions:

1) Make sure you are in Wright Isles with no wind activated.
2) Just set Throttle to 100% as soon as the game starts
3) Change cameras and enjoy.

Timeframe:

T-00:00:00 Booster Egnition
T+00:00:02 Lift Off
T+00:00:07 Heading Manuever
T+00:00:15 Pitch Downrange
T+00:00:30 Pitch Slowdown
T+00:00:41 2nd Stage Egnition
T+00:00:47 Stage Separation / Hot Staging
T+00:01:38 MECO / Flip Manuever
T+00:01:54 Gridfins Deployment
T+00:02:06 Heading Correction
T+00:02:22 Entry Burn
T+00:02:38 Trajectory Correction
T+00:02:57 Landing Burn
T+00:03:04 Landing Legs Deployment
T+00:03:05 Pitch Correction
T+00:03:22 Touchdown

NOTE: The actions above are not programmed by time but by flight milestones, so there might be a small deviation to the above timeframe.

Project Details:

There are NO magic gyros included. All stability, motion, and control are being controlled by 11 engine gimbal motors (1 for pitch, 1 for roll and 9 for yaw) and with 4 gridfin motors (2 for pitch and yaw and 2 for roll and yaw). Engine throttling, timing and management was also insanely crucial.

Feel free to open the input section in overload for the engines or actuators/motors to see how I did it. Spoiler alert: It's not pretty

Something amazing I discovered was that by trying to address problems without using in-game gyros, so making it as realistic as possible, I ended up programming maneuvers I later found out exist on the real rocket as well.

Falcon 9 Model Similarities:

Scale 1:1
Mass 1:1
Combined Thrust 1:1
Engine Gimballing
Gridfin Utilisation
Autonomous operation
Landing

Falcon 9 Model Differences:

Hot Staging was utilized in the model.
The center engine is overpowered compared to the rest but the combined thrust is the same as the actual one.
No RCS Thrusters in the model because they are too weak in the game.
Lower Speeds and Altitudes in the model due to the landing mission in Yaeger Island.

MESSAGE: This is my favorite project in this game because, for the first time, I used it as a platform to "simulate" mechatronics and combine flight mechanics with programming. I had no idea simple planes could be that much "not simple". This game is amazing. I hope I inspired you to go make projects crazier than this. Feel free to write your thoughts down.

Keep Creating, Keep Flying.

I'm going to sleep
