I´ve set spoilers on #3 mixed with #5 under Acro Mode. I can´t EPA on #5, looks like if its attached to a mix it can´t be trimmed. Sub-trims worked fine. I guess I can set a new mix to add a little Elevator when spoilers are raised.

#7 and Gear switches still work and I ought to be careful no to touch this when airborne since both opens the right spoiler.
