So what I do is to launch and immediately pitch until it is 60 degrees east. Then get a apogee of around 120km. Then wait for the perigee to rise over 70km then turn it back down to ~29km. After a while, it will reenter the atmosphere and eventually crash for some reason
The drogue chutes never opened, it never let me to. And also I needed to ship 9 pax altogether but I only do 4 at a time, pls check on one of my old post, it shows how my craft looks like. I have all of the level 4 except for aviation. But the hitchhiker module is level 5 (it is part of space exploration). The batteries, thanks for your advice, (I never realized it before), have almost never used any electric charge during the whole flight (however did use some). Shall I get rid of the whole service module or put 2 batteries instead?
