Mix and match stacks or ECS combos even if they aren't the same mounting pattern with the Stan FPV 20x20 / 26x26 "soft mount" vibe dampening converter. For example, use a 26x26 4-in-1 ESC with a 20x20 ESC and the FC gets complete soft mounted with zero touching the vibrating frame at all, even it's bolts!
