@Brainstorm - there are three fc versions for each size class of frame. The e011 stock components would do wonderfully in either the e011 version of the boss 7 (2.5g) or boss 7xl (4.5g). You need only add bigger props and flash the fc with silverware. The Boss 7 is smaller and still strong enough to take a beating. My video in post #98 is stock components plus bigger props. The xl is just bigger/tougher. The nano qx fc won’t fit any of them. The indy fc will fit all of them - just select the INDY mount pattern.
@Brainstorm you may appreciate a size comparison of the boss 7 running 50 mm props with a whoop. Much smaller footprint than the 90 mm frame
