Kevin,

On the 10X if you want to use ailerons as spoilerons you may want to go the single flap channel route then use one of these to get the reversed flap. it even has a servo centering pot. This frees up channels and mixes versus even BVM mixing instructions. Quad flaps is very free mix consuming to get to spoileron use.

This is my preffered method for BK, KC, and ViperJET
