After 205 inches of snow this winter, I'm finall able to start knocking off some test time on my 601 XL. I flew the 11th hourof testing this arternoon. What a teriffic airplane ! I'm getting more at ease in it with every flight. The Corvair is running strong, and I'm seeing 1000'+ climb rates with my 190# and full tanks. I initially had to adjust the horiz. stab. angle down 2 deg. I'm still tweaking my cowling a bit to improve cooling at high climb rates. The flaps are a real asset on the XL, allowing for some really steep approaches and slow touchdowns. It's really hell to be condemmed to have to fly this thing every chance I get to satisfy the testing requirements when I could be sitting at home watching Oprah.
