Well, yesterday was the big day. N558RV took to the skies for the first time, and with the exception of a few minor issues flew great! I'm breaking in a new engine (Superior XP-IO-360), so I just did laps above the airport for a half hour or so, but I was pretty happy with how everything worked. The issues I had were:
1. Round analog ASI and Dynon D180 airspeed differed at low speed by about 10 knots.
2. Oil temperature readings were erratic, and when they worked a little low (160 F)
3. Radio transmit is reported as very broken. The radio is a ICOM A200.
Two of those items are already fixed when I took the airplane up for another 1.6 today. I did a pressure reset on the Dynon unit, and now the airspeeds agree within about 2 knots all the way down to stall speed. I removed the wire to the oil temperature sender, scuffed the terminal end up a bit and reattached it. That fixed the erratic readings, and they are now very steady. And I blocked the oil cooler (baffle mounted) and had oil temps in the 200 F range.
My remaining problem is this: I did a quick check of the radio, coax, and antenna on the ground and everything seemed in order. I did a radio transmit check between a handheld and the aircraft radio and it seemed okay. (The handheld was only about 30 ft from the aircraft, however) The radio is receiving great. Everything sounds clear, and the range is at least 40 miles when airborne, probably much more. When I went flying this afternoon, however, the transmit problem was not fixed, and I was very nearly NORDO when I got back to the pattern as nobody could understand my transmissions. Does anyone have some suggestions on where to start trouble shooting? The Headset is fine and was used in a different aircraft two days ago without issue.
Thanks in advance the help!
