JOHN HAMMILL in Tamarack's CJ, Climbs to FL 400 in 20 Minutes
"I want to thank the Tamarack Aerospace Group for the opportunity to fly its CJ, equipped with your Active Winglet technology. Without question they exceeded my expectations - which were already high based on your reported data. I would expect Cessna to incorporate your winglets on their entire fleet as quickly as it can be done. Your Active Winglets will be a huge marketing advantage for them. Climbing to FL 400 and maintaining 1000 ft. per minute climb though the last 1000 ft. of climb was most impressive. In my CJ1, I fly in the FL 390 – 410 range quite often and normally take 40 - 45 minutes to get there, usually requiring an intermediate stop for a couple of minutes along the way.
Another observation; after reaching FL 400, the aircraft accelerated to cruise much quicker than I experience in my plane. In addition, when I disconnected the autopilot, I was very impressed with the responsiveness of the controls and the stability of the plane. In my opinion the plane is also a much improved instrument platform when hand flying in the landing configuration. Please do not hesitate to use me as a reference to anyone considering your winglets. I am certainly looking forward to getting my plane retrofitted as soon as possible."
