Thruster Kit

Summary
While many of the original design concepts for machines such as the original 15 did include a form of hovering system akin to magnetic levitation or rocket thrusters, their technology is not the most realistic when it comes to the universe they’re situated in. Thus, any AEG15 Unit that was originally depicted to have Thruster or maglev technology will only have standard legs. Only HMT or HMT II Units will keep a form of the hovering system, which has already been established as a modern design. The difference between the HMT and HMT II Units is that the former ran on external fuel canisters in order to compensate for the increased energy drain, while the latter are equipped with Gyrotumbler Units.

Standard Thruster Kit
A Thruster Kit that allows for short bursts of movement and assisted jumps. While it requires no external fuel canisters to operate, they are incapable of hovering and can only be used for unique movement schemes. Most commonly seen on mass-production units, it is easy to produce and requires little modification to function well.

High-Mobility Type Thruster Kit
A Thruster Kit that allows for low-altitude hovering and assisted jumps. Being derived from the Rocket of the FGC, this prototype-use thruster Kit would be seen on all Project X units. They were intended for improved movement across terrain, not increased speed. Of course, these would require external fuel canisters for prolonged use.

High-Mobility Type II Thruster Kit
A Thruster Kit that allows for low-altitude, high-speed hovering and assisted jumps. This improved version of the HMT Thruster Kit was built for speed, being over three times faster than the original. Its energy efficiency was also upgraded with the introduction of a Gyrotumbler Unit. They would be seen on all derivatives of the Majestic (those being the Kingship and Pegasus), though other units existed without Gyrotumblers. Variants of this system were capable of unassisted flight, though only one copy of this was ever built.
