I've ha[img][/img]d my aero ace for some time and it has worked great. I modified it to fly real slow by adding lots of wing area (taped on 1/32 x 3 inch ba[img][/img]lsa wood additions to each wing tip with one inch overhang at the back trailing edge matching the wing curve. The extra wing area didn't seem to slow the plane down much ( must have lots of reserve power) so I also added a bit of extra elevator trim area with up trim and got the plane to fly at a fast walking pace. "Way cool" --- with the elevator mod it didn't turn very well but I just read that if you turn the motors slightly to the nose of the plane it will aid the turns greatly. With the extra wing area added I had to add a bit of nose weight via a small screw. I think if I trimmed some of the added wing area off the leading wing edge which should move the center of lift backward I should be able to remove the nose weight. If you add extra wing area be sure to look at the plane from the front and be sure that each leading edge and trailing edge are level with each other both back to front as well as left to right.

I've also heard that some people took off the bottom wing and glued it to the end of the top wing. (Should be less total air drag and plane should fly slightly faster.)
