Never said that they will build the other two gravions, though I am looking forward to this too. But Ultimate Gravion put a lot of stress on joints, SENTINEL is good outlook and bad at design. High risk of joint breaking again
I WAS sentinel fans in the past, but the QC and design frightened me. SAD in every time, I need get exchange nearly 100% for all Chokin.......Wrong parts, broken parts, stupid design without considering simple physics, just concentrate on outlook. Studio Half eye is fragile due to material but the designer has put physics into the design.
