Originally from the KSPX parts mod, the Rockomax 48-7S is the non radial version of the Rockomax 24-77.
Usage
Like the 24-77, LV-1, and LV-1R, the 48-7S is intended to propel probes and small crewed craft, using light weight command pods and small fuel tanks large amounts of delta v can be achieved with little mass. Due to its relatively high Isp and thrust to weight ratio, the 48-7S is remarkably capable in ascent, transfer, and lander roles. It also has thrust vectoring, unlike its radially attached counterpart, the Rockomax 24-77, allowing for greater control.
Product description
| “ | A cousin of the 24-77, the 48-7S is a stack mounted probe engine that packs quite a punch. | ” |
| “ | The 48-7S may be small, but it packs quite a punch for its size. This little engine is a testament to how larger does not always means more advanced, at least according to Rockomax's marketing department. The box it comes in is pretty cool, in any case. — Rockomax Conglomerate, 0.22 |
