We are running one in the Skymaster ViperJet XXL. Excellent combo, engine flawless so far. We originally wanted and flew it with the borrowed K-310. It was a brute for this airplane. The 310's were/are held up right now so we went with the 260. Glad we did. Plenty of power in the vertical and with the 180mph speed limit on the airframe we just didn't need that much engine. A real joy to fly and engine is awesome. Will report any issues if they occur. Less than 10 flights in right now.
