I have been flying the Airmaster prop on my Searey now for 100hrs including a cross country flight from Orlando Florida to Vancouver BC (4500km's). The Searey easily maintains a 110mph cruise (115 when pushing a bit harder), which is considerably higher than expected for a Searey. Takeoff distances are also significantly better and performance on the water is excellent. I am especially happy with the reverse pitch (beta) option and I find having the ability to back up on the water and on land is very useful. Thanks for making such a great product!
