The work lasted for five months, but it took a long time because there was not much free time.
The appearance is still unfinished (I remember changing the appearance really often).
The booster at the end of the video was installed just for fun. A long wing booster will be installed on the back.
I'm working on something that changes the direction of fuselage propulsion depending on the camera view, but it's full of glitches.
I need help from someone who knows about this

And since there is a post written before the screenshot log, I plan to update it occasionally.
