Concering the switches on the TX.
As a lifelong modeler and full scale pilot I try to use words that can't be misunderstood by anyone in reference to the switch position.
I don't say "dual rates on or off' or flight mode 1 or Flight mode 2. In reference to my dual rates I say High rate or low rate. Now direction of switches, Assuming they are oriented the same way as the main sticks, for High rate I use toward the top of the TX and low rate toword the bottom of the TX. If I am test flying some one else plane I always make sure I understand the switch location and their configuration. Then during the flight if I am not sure of switch selection I will tell the planes owner to standby and move the switches if I get busy doing other things.
NEVER take your eyes off the plane especially to look at the TX to move switches. I have seen several planes out of control following that stunt as the pilot tries to visually require the plane, and some crashed before that is done.
