Owned and flown them for years. I have run the 2.4, 3.2, 3.4, 4.2 over the years and they are all very powerful, user friendly, and reliable. They are top shelf in my book. Kurt is very helpful and his customer service is flawless as far as I have seen. I sent a 3.2 in for much needed service after several years of service and two crashes, and he turned it around in one week, as I recall, good as new with the old parts in the bag for my information. You won't be sorry if you choose one. Here is a 2.4 in a Christen Eagle I built last winter. As you can see, they are very nicely crafted.
