4 Rotary Control Knobs 8 Programmable Pushbuttons – See the GF-P8 module for description Each of the control knobs on the RP48 can be used to adjust instrument panel settings such as Altimeter, Gyro, OBS1 and OBS2, as well as many others.

When installed with GoFlight home cockpits that include GF-45 or GF-166 modules, the RP48's knobs can be programmed as Mode Selectors, allowing you to select all available avionics modes on the GF-45 and GF-166 modules.
