FR7 SA with flair

This is off the straight arm edition of the FR7.

I've added a central 20x20, and a row of 20x20 in the rear.
Added additional vents to reduce weight.
Redid the arms influenced by Bob Roogi's design.

edited the batt straps to add .25mm extra carbon to beef them up.

6/21/19 - added interchangable arms - they interlock, and overlap enough that it shouldnt be a problem. Rear and front use the same setup now. (Just like last image)

10/20/19 - adding a keystone stl to 3d print, this fits in between the arms to add some more pressure
