Just wondering if a gusset on the attachment point for the strut rod might be appropriate. QA1 has the tube for the strut rod gusseted on both sides for added strength.
The HDK / LCAs pictured are tacked together test pieces to evaluate component placement. In fact, that is precisely what I was doing when I snapped the picture to send to a customer......and my brother to give an update on progress.
Good observation.....I agree, that area needs to be beefed up.
