Essential
You need this in your fleet. Most standard engine rockets use B engines. B6-4s aren’t too low or too high power engines with a good delay time. It’s perfect for rockets of all shapes and sizes.

the best overall engine
This is my overall favorite engine. It takes just about any stadard engine rocket and kicks it off the pad. This thing will propell rockets to adaquate heights that are still easily visible. This engine produces the perfect flight for the EPM 010, my favorite engine!!!
