The main reason I like to follow sudjest end guidelines for throws is that I have an edge 540 and the sudjest end throws were 1/4 up or down on the ailerons. I thought that wasn't enough throw so I made it full up and down. After takeoff with the slightest left aileron I did a roll 3' off the ground. I crapped my pants
and after that I was told to use suggested throws as a starting point and adjust from there. So I do!,, maybe it does end matter with these cheap foamies but it sure does on sport / 3D planes.
