Hey, guys!!! Today, I confirmed with my
own eyes that the groove exists on SAC sixth gen!!!

I paid special attention to the groove this time. The conclusion is the same as the last time but just with more clarity and, therefore, confirmation: the groove doesn't ruin the
aesthetics of the plane. The groove looks just fitting for the plane. In fact, after finally visually confirmed its existence, I find it
hard to imagine a better looking belly being completely flat. I can
personally assert that the plane's
groove is so visually right that it makes the plane
look better aesthetically!
