Sergio, are you asking for the UCD? I thought you already mastered the flatspins, but if not (this is just an estimation since i crashed mine) but i never got mine to do elevators because i think there is too much wing area to let it drop without stalling one wing(wing rock) but flatspins are a diffrent story, it does them great, the inverted flatspin better, my cg was at 5.75in and all the elevator i could get and all the rudder i could get, alierons will work with moderate settings to stabilize the wings horizontally in spin

nice Edge, where did you get that? and i like the canopys two tone[8D]
