Spent a great deal of time on laying out the EFIS, radio stack, and switches on the instrument panel. My goal was to have the electrical bus switches and ignition switches on the far left. They generally are set for startup and not manipulated again until shutdown. Light switches, pitot heat, fuel transfer pumps were located under the radio stack. Dimmer switches for the panel to the far right. My infinity aerospace control sticks have the start switch, fuel boost pump, cowl flap and strobe switches as well as controlling four avionics functions. Difficult decisions were made on locating the engine controls. Ended up leaving them on a sub panel. A last minute decision was made to include the audio panel in the radio stack instead of a remote unit. Ready to send the panel to Superior Aircraft Components for cutting, coating and labeling.
