I had the opportunity to fly Dick Carville's Sieverling Mustang yesterday, over in Wrentham, MA. WOW! This ship flies incredibly well! Dick is a superb builder, which certainly helps. The P-51 was one of those special stunt ships that is easy to pull through the pattern. Dick built the plane from plans, and put in a ST 46 to help it along. What a really nice combination! Hope someone who was there will post a photo; Dick is an excellent finisher as well.
