There were also some good, rational reasons for taking the RV-6, of course. For one thing, it's a fair distance to southern Utah from San Francisco, and the RV is almost 50 percent faster than the Cheetah. In addition, Bryce Canyon Airport has a field elevation of almost 7,600 feet, and we were planning the trip for Memorial Day Weekend. Which, in the southwest desert, can be pretty darn hot. And from past experience, I know that on a hot day, with two people, bags and fuel, my particular Cheetah can be hard-pressed to maintain 8,000 feet msl. Besides. Aside from a couple of quick demo flights at the Van's Aircraft facility in Aurora, Oregon, I'd never flown an RV-6.
