Explanation
Two motors both forwards rotating only ,mine can be operated independently or together at the flick of a switch
Two reversing buckets independent of each other
Two trim tabs that need to respond to speed and bucket operation
My trim tabs deploy proportional to speed
Each trim tabs is mixed with each bucket to come up as bucket goes down
Not overly complicated
actually simplified and any flyer should be able to help you with mixing
Two jet steerable nozzles can be unified but mine are separate and mixed to work together. This way if one servo circuit fails I still have steering
