I have just purchased an Aero Works 40-60 size Edge 540T with an OS .91 from another club member. This is my first hi performance plane, and the person from whom I got the plane is much more experienced than I am.

When I installed my receiver and started programming my tx (Futaba 6ex 2.4 GHz) I was amazed at the throws that resulted with the way the servos (JR ds811s) were setup. When I used the end point adjustments to set the throws to the book values they were in the range of 25 to 50% for hi rates (no 3d yet) depending on the surface. I talked to the old owner and he said to set the epas to 100% and use the hi and low rate settings to limit the throws. I haven't had a chance to do this yet, but I am assuming that the percentages will be similar - if not the same.

I was told, and read in instruction manuals, to set the mechanical linkages to get as close to the recommended throws, then use the computer radio to tweak them in to the final settings. Since his advice goes against what I am being told/read my question is why does he set his planes up this way? Having the servo limited to 25% of its maximum throw would seem to limit resolution which would not seem to be desirable IMHO. Anyone else set up their planes this way? If so, why?
