Been flying the 6A since 2004. Came time for a panel upgrade and did a lot of cost benefit before settling on replacing my Century 2000 AP/Servos/AI and HSI and an RMI micro encoder with 2 Garmin G5s, Garmin Servos, and GMC507 Autopilot. Removed suction system entirely, lost 21 lbs of weight, gained a flight director, many additional functions, and kept a combination of old school panel and new technology. Kanardia EFIS was installed in place of the Altimeter last year and it slaves data to the AS and VSI via a can bus. Clock and Turn Coord replaced with 2 AV-20s. Total labor on my end was 40 hours. Flew to Billings to have Andre connect the G5s to the GNS430, Audio Panel, and Transponder. Aerotronics did my original panel in 2003 and did an amazing job. I highly recommend them. Good people, amazing service, and quality product!
