Like JimS, I will also be replacing my round vacuum horizon and DG with the G5 in my RV6A. It’s a great replacement instrument which can be configured to your liking. The price is right at $1200 a piece for non certified aircraft. However, if you have a new panel, something more “glassy” might be better. However, IMO, anything more than a compass and a turn and bank on a Kitox is overkill.....especially if you want to save money for stuff like...fuel to fly. Keep it simple and go fly. The Kitfox is the best thing in sport aviation!
