CYLERO X (Final Complete Version)

This is the final version of the Cylero X project, please read the inroduction below, that is important andmake you fly this vehicle much more easily. [Skip to the next paragraph if you want] I am really sorry that I still use tinker pannel for the final version(only for all four side boosters and its nose cone, I set their mass scale to 60%)that's the best I can do without making a lot of big chanes that fully make the rocket diifferent from what it is like compare to previous generation. it might not be that not because this is my first time making a rocket, it has been 13 generations once the final version release. it took me a lot of time on making it , so if you like it, upvote it please.
Back to the rocket itself, turn it to the max throttle before you fire it up, once side boosters run out of fuel, cut off the main engine, and once it reach its apogee(at about 100km), use the rest of fuel to reach low Droo orbit, generally there will be a few meters of deltaV that needs to actually reach the Low Droo Orbit.
( Best gravity turn angel and it's corresponding attitude: turn 45 degree at 5km and wait till 30km, then turn 30 degree at 30km, then turn 15 degree at 45km, the boosters will be separated at about 53km)
Then stage 2 and stage 3 are the two stages that provides thrust for going to Cylero. Generally there are a few hundred meters of deltaV left for you to slow down before enter the atmosphere if you want.

Once you enter the atmosphere of Cylero, release the parachute to slow down, at that period, make sure that activation group 7( RCS for upper stage is off) so that you won't waste too much mono during the entry, then at an attitude of about 15km, you should use the engine to slow down and land with landing legs.

There is a rover for two astronaut to use, first activate AG 5(the cargo bay), then activate the AG called pistons for rover, then you can use slider 1 and 2 to pull the rover out from the cargo bay, wait till the rover is not shaking too violently, because there is a few meter to the ground due to the size of the cargo bay that I can fit in these pistons, then activate stage 13 to release it,
(you can make the cargo bay bigger to fit in your rover bigger if you want, but make sure it's not too heavy). Also, lights are placed on the front and back of the rover.
Back to the upper stage, after the astronauts enter the command pod which is designed for re-entry, activate stage 14, four solid rocket boosters will be burnt for about two seconds. During this time, activate stage 15 and max out your throttle,. Then reach the Low Cylero orbit at an attitude of about 100km, about 40-50% of fuel will be left if you use it wisely. That's about 3,000m of leftover deltaV, it helps you get back to Droo easily.
I recommaend you to enter the atmosphere at an relatively small angle with the perigee of 30 km. Make sure you activate the AG RCS for only re-entry before re-entry. Release the small parachutes for slowing down at 5km AGL and release the main parachutes at the AGL of 2km. That's the end of the introduction. Hope you like it and give me an upvote!
