+
+P series supports configuring receiver from transmitter. Originally, this logic appeared on DumboRC DDF-350 transmitter in 1.1.5 firmware version.
+
+You can adjust these settings by using "DumboRC P Series.lua" script.
+
+Settings include:
+* gyro on/off
+* gyro phase
+* gyro tuning
+* gyro gain channel
+* setting gyro endpoints
+* setting failsafe values
+
## Futaba - *21*
Also called SFHSS depending on radio version.
