@
billms@gmail.com - there are many ways to achieve an outcome.
A simple way to look at EXPO vs RATES with OTX is to put the EXPO on the INPUTS channel, and the RATES on the MIXER channel.
image 1 - I am adding 30% EXPO to the INPUT for the ailerons
image 2 - I am creating a FLIGHT MODE with a GLOBAL VARIABLE at 70% and assigning it to SWITCH A in the up position - I could then set another FLIGHT MODE with a different RATE on another SWITCH position.
image 3 - I am assigning the GLOBAL VARIABLE to the WEIGHT of the ailerons - what this does is change the RATE with the flick of the SWITCH - without affecting the EXPO
Do not worry about the output channels in this example.
This is a simple starting point - you could also put EXPO on GVars (GLOBAL VARIABLES) too, so the EXPO changes with the RATES - and many other wonderful mixes, but I hope this helps with your EXPO and RATES question?
