One of the key characteristics that differentiated more skilled mech designers from their less proficient counterparts was their mastery of hyper technology.
Although hyper technology was not as difficult to learn as phasewater technology and other alien-derived technologies, it still took a lot of effort to learn or figure out the more advanced applications of hyper materials.
The previous fey models that Ves examined such as the heat disperser fey only made shallow use of hyper materials.
On the one hand, that was an advantage as the fey models were cheaper and easier to build.
On the other hand, the basic implementation of hyper materials heavily limited their potential and constrained their options.
