The flap servo is really close to the aft of the pedestal. I tried to use a carbon plate servo horn set up like my wing drives but it didn't work out, so I went with a stock ball link set up.. The position of the ball link is critical to full operation/travel of the flap, so take a lot of time to get the right higth. I had to carefully smooth over the top wing mounting plate inside the fuselage, and then clearence the metal quick link on the servo, the plastic ball link body and slightly open up the pass through to make it all fit and work right. It took a lot of time to get right, but it works and gives both up and down travel of the center flap panel

The drive link is a simple short piece of all thread with a ball link and a clevis
