For Tiny 2 adding settings/switch.xml in "settings" of your conf.xml

No, both Tiny versions are the same. The 1550 neutral was a workaround
for some brushless controllers. When using the XBee there is a 2s delay
at startup where the 1,5ms default servo pulse length is sent by the
servo driver (4015, 4017). Some brushless controllers sampled this and
use it as minimum value and were confused by a lower value after
startup. The 4015/4017 is now changed to give the MOTOR_NEUTRAL defined
in your aircraft config file so the 1550 is not needed any more, use
1000 1000 2000.

Yes. If you compare them you can see that only the battery voltage
calculation is changed (to adopt 2_1_1 to the Tiny2 default battery
