Below this are more pictures of the rocket in action. Steps given throughout are complex so pictures are used as a guide. I recommend reading the ENTIRE post if you want to use the rocket as how it is intended.

Here at SaturnVDynamics Inc, we have officially created the StarGazer 1.4. The Stargazer 1.4 is a heavy cargo rocket capable of sending heavy satellites like the Cubesat 1.3 which is a CubeSat to a very far orbit from Droo.
Heres a pic of the Cubesat 1.3:

It can send the payload all the way to near Luna, but not quite enough delta-v to capture around Luna. Due to the reusability of the first stage, its important to follow these very important steps that are going along with the pictures to show how to takeoff, thrust settings, how to land the first stage intact back, the orbital science to get the payload to space and then just some controls to know like Activation groups.

First off is takeoff, the only way to get to places is by moving. So first put the throttle at 70% as that is the throttle settings to use fuel efficiently so you can get a start. So once the throttle is at 70% press the stage button and let the main engines start.

THIS IS 70% throttle right now in these images
Also, keep in note that the side 4 booster/engines are NOT reusable and only provide the extra oomph in the liftoff. Once the side 4 boosters fuel has depleted the center core stage should be running, detach the side boosters and increase throttle to 80%. Remember to do the gravity turn. You should have naturally done the gravity turn at the point you know its best.

Above pic is the side boosters separating. Now here's the very very very important thing to keep your eye out after the side 4 boosters separate. Make sure you burn your fuel down to 10%. Save the rest 10% for use for landing back down. Once you detach the core first stage (which is reusable), keep burning the second stage at full thrust into orbit the fastest you can!. Once you burn out all the fuel and see you are far from the apoapsis, go to map view and click on the descending booster stage. Now click the altitude marker on the UI and make sure its AGL so you know how high you are from the Ground. Then enable Activation Group 1, then click add slider 1 and then slide slider one down. Also make sure your landing spot you can approximate is a gently slope or no slope, as it will tip over and blow up on steep slopes. The air brakes should fold out outwards and should help slow the descent easier all at the same time making sure you are selected on the retrograde marker to follow. Then from there, the rocket should be like this:
.
Now keep descending without using any fuel to about 1500 meters AGL and then when 1500m-1600m AGL comes, fire your main engines at full thrust to slow down and then once you canceled most horizontal velocity like so:

make sure to switch from following the retrograde marker to heading lock at 0 degrees pitch or also known as being fully upwards direction. Then when at a decent speed coming down stable. Then land slowly which is about up to 6m/s towards the surface. Make sure that also your landing legs have deployed. And there you go once on the ground you have successfully landed the core booster to Droo's surface in hopefully once piece or mostly intact.

BUT DONT FORGET, YOU STILL HAVE A NON_ORBITAL CRAFT IN SPACE. Yeah, don't forget about that payload in space if you want it to get an orbit. Pretty much from there, you should be able to get into orbit easily and send your CubeSat into an orbit around Droo. :D Also there is a cool feature on the CubeSat 1.3. Press AG9 or 9 and the solar panel should extend, and if you press AG1 on the view of the probe and push slider one up it will extend the "antenna".

Btw: It may seem overwhelming at first, but you will get the hang of it quickly if you have followed these steps Thanks for reading this rather lenghty post and I look forward to putting more content out soon!
