I don't have any pictures handy to show, but they don't interfere with the manual flap handle. Of course, you decide exactly where the pedals get mounted. They don't come with plans or drawings or anything, just some prior planning made sure it was located where it wouldn't interfere.
Only interference is the Passengers foot when reaching for the flap handle. Lucky for me, my only passenger is typically my wife and I just ask her to pull her left leg back when I need flaps. FlyBoy pedals stay nicely tucked out of the way.
