I have a newly built 2007 Arion Lightning experimental airplane with new FlightDeck D-180. The Oil Temperature gauge on the Dynon is not working at all. The Airspeed indicator on the Dynon is inaccurate on the low side. We think it is at least 30 mph less than what it should read. We had a mechanic who thought there were some leaks along the airline that goes from the pitot tube to the instrument, so he tightened some fittings up, and that helped some; we are getting more of a reading now, but the reading is still off. ALSO, another problem we have: When we put the strobes or the navigation lights on, the amperage goes below normal to the redline, drawing heavy on the battery, so we never use the lights. Plane is in Hagerstown, MD. Any help or referral to someone who can fix these issues is much appreciated.
