Stearman with 2-blade fix Propeller
I am extremely pleased with the propeller and its performance
---
I installed an MT wood propeller on my Continental 220 HP Stearman approximately 100 hours ago and am extremely pleased with the propeller and its performance.
The MT replaced a McCauley metal propeller subject to AD 54-12-02, which requires disassembly and magnetic inspection of the hub and blades every 100 operating hours, and restricts operation between 1,500 and 1,650 r.p.m. The MT is not subject to any AD's and has no operating restrictions. The MT is also 25 pounds lighter than the McCauley.
The MT's performance is comparable to the McCauley's. There is a general feeling in the Stearman community that metal propellers out perform wood. However, I recently flew during formation training with a 220 HP Stearman equipped with a Hamilton Standard metal propeller. Although both airplanes performed comparably in cruise, the Hamilton Standard equipped airplane lagged so severely in climb performance that I routinely had to reduce power 100 - 150 rpm so he could remain in position during takeoff and climb.
MT-Propeller USA and general manager David Noad made purchasing an MT a pleasant experience. David answered every question before I ordered, and immediately furnished additional technical information I requested after my prop was delivered. I frequently tell people, "Contrary to what we've come to expect in today's world, MT did everything they said they would do, when (or before) they said they would do it, and for exactly what they said it would cost."
Thank you for making a great product.
