Have 5-6 motors and 4-5 ESC`s from Hyperion.

Their motors are "cheap but OK", like AXI etc. Not the best but they work good for most flyers! Have seen/tested the stuff a lot... Two identical motors did measure very different, and I have noticed some inaccuracy/slop in bearings. Often they wibrate when frontmounted, but works much better with backmounting.

Their ESC`s: Have had some odd behavior on startup, and seems like the software is "OK but not the best". I usually get more power from motors using Jeti ESC`s... And have several times experienced fading in motorpower when I run them at close to max load. Even before they have a chance to get hot. Won`t buy more of their ESC`s.
