Whilst playing around with the instrument on the 6th, I found that the Dynon unit that I had purchased last year through Spruce did not work. When power was connected, nothing happened. I rang Dynon tech support, Steve, who advised without any hesitation that it would be replaced under warranty and that a replacement would be sent immediately provided that I returned the original. What fantastic support. Away for a bit more sunshine & surf for a few days and finally back into it again today. Started the marking and drilling of the turtledeck.
