Productive day... Re-wired the connectors to the USB ports and lead to the ipad dock after failing to get them to work yesterday. Works fine now.
Fitted a pair of mounting brackets between the lower panel and the cross beam, which aided stability of the panel enormously.
Made an RS232 cable and conneced t the main EFIS and the Com 2, to allow remote control of frequencies.
Fitted the G5, including the pitot/static lines, and also prepared the alternate static port, but need a 1/4 NPT female-female adapter to finish off the installation.
