Sorry to hear the bad news. Do you have a local club, guys love to help.
I installed the bell crank system in my wings tonight and I really dont like it there seems to be to much resustence so Im going to tear it out and do what you did go with seperate servos for each arelon and flap. Im just going to cut the belcrank plate out between 8& 9 and put in a servo mount. like you did. However You dont have a photo of the servo mounted. How do you intend to mount it since space is very limited. I figured you would have to lay it flat to fit inside the area.
