Where do you want the lever to be positioned when the flaps are closed? Lever position when the flaps are fully deployed? Do you need the flaps to reflex upwards? Do you want the auto land capability? How much flap servo travel do you need, +/- 100% or 0% to 100%?

When I set the flaps up on my 12X to see what it took to get them working with the lever, I took a very quick approach by assuming the flaps were closed at the lever detent or half way position and open at the lever extreme positions. You may want something different.
