I have started to get in my Hyperion ESC`s..These ESC`s are great and have a perfect feature..They come with a remote..The remote allows you to program the ESC via the remote while the ESC is in your craft..No more beep or computer programming, do it at the field from your remote..These ESC`s combined with the proven and powerful Hyperion lipo`s, are a perfect match for your craft..Im getting the batteries and ESC`s in every week now..
