Futaba has an (air brake) selection that works very well. I set my Edge up with 10%down ailerons and 5% up elevator activated during low rates on switch (G). Used them a few times during zero wind conditions. Can't be used with a Y-harness on ailerons. Flaperons and duel channel ailerons only. "Hope this helps."

Manny ?? Do you have access to a camera ? Maybe if we could see where your at on the wing joiner it would be easier to help you.
I know VF likes seeing a snap shot or two as well. I had made a mistake on my joiner by getting one too far into the left wing.
Simple solution was to drill out larger lockdown holes and install the next size bolts and wingnuts.
I bet you'll get a fix from VF before you ever read this . They don't waste time helping their customers.
