Brief Description: Spring Rotorfest -- Rotary Aviation Gathering
8 Mazda powered airplanes flew in. Bill from Wyoming, Tracy Crook and others from Florida. Excllent presentations and information. Nice to see 8 installations and compare notes between them. 20B Lancair, Supercharged Renesis, to 13B's.
Noise, the Renesis exhaust port does the best in keeping noise down, and getting exhaust mufflers to last. Dennis H also had a very nice intake manifold that was turned for 6800 rpm, giving a prop speed just under 2400 rpm. He had flown for a year prior to the new manifold, so good data to show the performance improvement from the manifold.
Photo shows Bobby H's RV10 with a supercharged 13B Renesis. Interesting option.
