I switch between mode 1 and 2 constantly as I use my hat switch on mode 2 to get the "UP" views.
A button is set to switch between mode 1-2 another to switch between 3 -4, Mode 3 setup for the CM eye, mode 4 the axis's are mapped to control TRIM instead of the axis.
So I can if I need to trim out of a compression dive, push a button, pull the stick full back, push a button, and be back in flight mode, with elev trim set to full up.
Its really not hard to setup.
In map controls, select mode 2, "copy mode 1" button. This gives the joystick the exact same setup as mode 1.
Then pick the button you want to use. Making sure your in mode 2, set button to "set mode 1" then change mode back to mode 1. Same button, but set it to switch to mode 2.
So if your in mode 1, push the button, it changes you to mode 2.
If your in mode 2 and push the button it changes you to mode 1.
simple alternating switch.
I use a MS sidewinder prec 2 with only 8 buttons, and I tend to be a minimalist where mapping is concerned.
But with the system that HTC gave us to play with you can do almost ANYTHING you can imagine.
