| Honestly, we live for trimming such as this in AMA/F3C flying, and I would suggest you set the swash timing at 0 degrees and tweak a mixer as needed to get a clean loop. The thing you have to understand is that with a mixer, you can isolate the trim issue to just the loops and fix it accordingly with an ele>ail pmix WITHOUT affecting the roll trim on the model. Swash phasing adjustments always affect both pitch and roll maneuvers, and it's difficult to get the two adjusted exactly right. The other thing already alluded to here is the fact that precise, incremental, and repeatable swash phasing adjustments are difficult. It's easy to confirm 0 degrees of swash timing and then incrementally tweak a mixer until the model loops or rolls cleanly.
