What is your appetite for workload? Over time, I've found that differences in stick tension, expo settings and to a lesser degree control throws, loom larger than switch location when I hand my tx to others for them to take a pull on one of my models. For my own sanity, I try to keep switch location consistent across models and keep switching to a minimum, in general. The ones I can reach without leaving the sticks are my go to switches, but may not work for others. What would you like to change in-flight? For example, many maneuvers can be made on low rates. Also, do you plan to take advantage of flight conditions as many do with high end radios? All very personal choices I've learned my first year in pattern.
