Well, I just couldnt wait any longer. I had to get started on my B-25 this weekend. I didnt like the way they had the control horns fitted in the flaps & ailerons, or the flap cables coming out the bottom wing sheeting. So I made the cables run along the upper side of the wing & I epoxied the horns into the flaps with the horns end exiting the leading edge of the flap, so as to help hide them. I also boxed in, & then cut out the flaps & ailerons before sheeting the wing. I have never had good results cutting them out after sheeting.
