0.6 flight time, 6x around pattern. Light weight. Took off w/ ~5.5 gallons, landed ~4.0. Needed to check the radio in flight. I think it may feedback on itself when transmitting in the hangar, as the squeal on transmit was gone, and Tim (hangar mate) was out in his plane at the time and said he could hear me fine. When I got back, I turned up the sidetone, as I had it turned down to not hear the squeal. With these adjustments, hopefully the next flight the radio will be back to normal. 31.7 hours total flight time, so Phase I doesn't have too much more to go.
