I realized this modification was just the ticket for those running a 6S setup.
If you notice there is a set of unused screw holes in both frame sides just below the motor mount. You may also notice that these are spaced exactly the same as the holes required for the lower frame brace at the back of the frame.
Matt evidently designed it this way so one could move the frame brace forward if you run a 6S setup. The will allow you to slide the 6S pack back against this brace then strap in the pack. The only other thing that must be done is provide a second frame spacer to use to attach the tail boom supports. I decided since I am not needing the gyro plate I would utilize one of those frame spacers (see attached photos). Of course you could also purchase a second spacer if you cannot sacrifice the gyro plate.
