SpaceX Falcon Heavy 1:1 (with tesla roadster)

I edited it to make it look like the real world, with almost the same resemblance. With 1: 1 size, similar propellant, and almost the same thrust in each engine, even the mass and price are very similar to the original. So with that similarity, you can't land all boosters at the same time, you have to land them one by one. How to use it to orbit and land all boosters in RSS:
1. Turn on the rocket engine to 100%.
2. tilt the rocket slightly up to 45 ° at an altitude of 50km, and reduce the speed to 70%, when at 66km lower it again to 35% and release the two boosters.
3. Quicksave and move control to one of the boosters. After that, perform a "Flip Maneuver" by turning the rocket back and burning so that it can land on the landing site.
4. If you have landed one or both of these boosters, then immediately for Quickload to continue the journey of the third rocket or booster.
5. Increase speed from 35% to 70% and tilt to 5 °. When it is 125km, release the third booster and do another quicksave.
6. When you have done the quicksave, move the control to the 3rd booster and land it in the sea or in "Droneship" if you can.
7. Quickload again and continue the journey so you can reach orbit.
If you follow this method, you can reach 7000-8000km earth orbit on RSS. If you want to get out of Earth's orbit, you have to use up all the fuel and not spare it. Good luck!
