Blasto BFE300

The BFE-300 is a large turbofan engine, which is usually used for large, heavy aircrafts. If used on a smaller plane, it will be incredibly fast, yet inefficient, due to the large amount of fuel it requires. It produces drag, and since the larger the aircraft is, the weaker the effect of drag. In that sense, it is incredibly impractical for a fighter jet. It generates a whopping 67,440lbf In comparison a 747 engine generates 60,000lbf.

Tips
It is a perfect engine choice for aircraft like airliners, large cargo liners, or heavy bombers. Just note when using this engine that it is 4x4 blocks, large unlike the previous BFE150 (Which is 2x2 blocks), or the J90.
