i think i am beginning to understand the dual rate vs epa thing better... at first you must make sure that the model is physically adjusted properly, i.e. the servo rods arent too long or too short etc... somewhere in the menus of my tx it has the option to set the steering's left and right maximum independently , and its labelled as 'epa'(end point adjustment), you dont change this often and you only change it when youve done some major changes to your steering system... and then right where your thumb will go on the handle theres a clicky wheel, that you roll to increase or decrease the sensitivity of the steering wheel as a whole, and its labelled as 'd/r' , you change this depending on which track you go to , maybe also the condition of the track...
oops i forgot i was meant to pretend that im talking about planes, but im sure that there are analogies for helping newbies understand endpoints vs dual rates in planes
When we say "adjust linkages first" we mean both the length and their positions of attachment to the servo arm and the surface control horn. By choosing the correct attachment points you can minimize the amount of EPA adjustment required to get the desired throw. Get the linkage close to ideal and then tweak with EPA and then set D/R if desired and expo too.
Don't get too fancy all at once and learn the effects of one function before experimenting with the next.
