Well, I made my first mod for my falcon... I really wasn't happy with the head and read about how a closed flybar was much better so I added one to mine. There are more Trex parts that fit the falcon without any real mods. I picked up part # AGNH1116 (flybar control set) and #AGNH1117 (flybar seesaw holder and mixing lever) I used the original control rods and turned the blade grips upside down so that everything would line up. So far everything is much tighter and seems more stable. Here are some pictures. it only cost me about $26.00. Oh and now my flybar paddles and blades come no where near my tailboom
