I installed the prop. controls today. The instrument panel is now complete with all instruments, controls and switches installed. BDH showed me how to access a DEMO mode on the G3X. You hold the "direct to key" down while powering up the PFD. Once the mode is displayed on the PFD, you enter a IAS on the speed tape and away you go. Through the autopilot you can turn, climb and descend in dfferent modes, very cool, the G3X is an amazing avionic system for a light aircraft.
