Jared what I saw was the inboard flap being too strong, causing some hingeing. You can correct that by adding a tab to increase area to the outboard flap or trim off the trailing edge inboard. The tab out board temporarily can clue you about how much to trim inboard permanently if you choose. Just cut and try until in turns flat both ways. If the hingeing is around 45 degrees and up its flaps. If it's on the bottoms its tip weight. A quick way to sort this out is do tight horizontal eights with the intersections up about 45 degrees. Watch to see if the airplane rolls one way then the other at the intersection as you reverse control inputs.
