So I was messing around with the first model I have up with my new X20. It's just an old foam mpx Heron but makes a great test bed for various things. With full crow brake deployed I noticed the right aileron did not have as much deflection as the left one so I went into the mixes to correct. That was my 1st mistake. This setting needs to be changed in CURVES, not mixes AFAIK The template I am using for this model is Mike Shellim's e-soar F5J with Lenny Keer's F5B mods added to it. I'm scrolling through all the mixes looking for anything that says right aileron and open them one by one and start spinning dials to change numbers while observing the right aileron. Nothing seemed to change the height of the right aileron. I tried another right aileron mix in the folder and highlighted a -100/+100 field and started spinning the dial looking for change.. Nothing happened but when I looked back at the radio, the whole page was going up and down and not the window with the value I was trying to change, I must have not highlighted that window. I backed out of that mixer and put the throttle stick up for zero crow brake and SURPRISE! both ailerons are now raised 20mm. So I go back to the mixers page and can't remember which mixer I was on to make this happen. I open all the right aileron mixes and start spinning dials again to no avail. I finally gave up and loaded my cloned model and deleted the one with the raised ailerons. Of course I had to re-bind but that was no biggie.. I started over and realized I needed to change the setting in CURVES for the right aileron. It would be nice if there was a "are you sure?" function you need to click on before changes happen in programming or better yet a "go back" feature where settings can be restored to a previous time before you screwed things up.
