Well, its been ten years, 10 months, and a few days. But at 1600 this afternoon RV-8 #80427 finally got airborne. I circled overhead CYSH at 2500 ft at high power for about 15 minutes, being sure to keep well within gliding distance, just in case. I then pulled up to 5000 ft to do a simulated approach and flare. Then I brought the power back up and pulled some g to descend on the north side, crossed over to a very tight downwind and final and landed. It wasn't the best landing I ever did (I had a small bounce), but it was the most satisfying.The aircraft has no major snags. There is a bit of left wing heaviness, and the front cockpit heat seemed to be pumping out hot air even though the control was OFF. I'll pull the cowlings tomorrow to give a good look at everything ahead of the firewall, sort out the cockpit heat, then if everything is OK, and the weather is suitable, do another hour circling overhead doing engine break-in.
