The Rockomax Mark 55 Radial mount engine requires fuel from external liquid fuel tanks, and must be either connected beneath them or be on the receiving end of a fuel line.

Usage

The Mark 55 is the third Liquid Fuel engine with thrust vector control, that allows efficient control of the rocket during descent and landing. The Mk 55 is fairly low thrust, however this is offset by its comparatively low weight. The engine has a comparable TWR with the LV-T45.

The low thrust (and radial mounting) makes a single Mk55 unsuitable as a main engine on most lower stages, but it can be used to augment other engines. A common use of this engine is in lander designs, as it eliminates the need to have a vulnerable engine in an easily-damaged position. The Isp of this engine is quite poor (290 at 1 atm and 320 in vacuum) which limits its usefulness. It is recommended to not be used in atmospheric landings.

As of 0.18.2, this engine has the highest range of gimbal with 3 degrees.

Description

After an intensive search for an engineer crazy enough to plan and build a revolutionary new engine type, researchers stumbled across Eugene Kerman - or, as he's known by night... THE CONSTRUCTOR! He failed miserably, and this is what we got instead.
