Yes, I had the stock 24 lb. flywheel, an adapator from flywheel to SAE2 flange, and an 8" extension. And the duct was heavier than I thought.
Temps were normal. I was worried about ground cooling, but that did not seem to be a problem as I was sitting at the beginning of the runway waiting for traffic. It was a very cool day though. The flight was too short. The real test is how it cools on an extended climb on a hot day.
