YOU MUST DOWNLOAD THE MODS FROM MY PAGE FIRST. The mods are in the posts section of my page. This is going to destroy all records and your mobile framerate. I recommend using this only on PC. To use, simply drag the throttle to 100 then activate group 1. This will boost you to around 1.16 million MPH. The engine is a modded j15 that I made. The air intakes and fuel block I also have modded for less weight. This is why the entire rocket only weighs 2,000lbs. I took the original fuel block from somewhere but have further modded it. (I have created all these mods personaly I think. If there is something you see on any of my planes that is yours feel free to call me out cause we all make mistakes)
