The 7HV design is sill evolving during the rigorous testing performed by Compass Team Pilots. The most notable change you can see in this CAD animation is the new lower frame design around the batteries. There still isn’t a definitive release date on the 7HV, but Team Compass Promises it will be released “When it is ready”. I’m sure Compass fans can appreciate that statement.
