Hi Chris,
From what I have read, with the 450, a normal runup can overpower the
brakes, so one must do checks at lower rpm than you would usually
expect. Yes, application of power during takeoff is a gradual thing
with this machine.
The guy flying it, as well as myself, believe that the 300 hp Lycoming
is a better match for a recreational airplane. The 450 just eats fuel
for little additional benefit, unless one is doing aerobatics or crop
dusting. And I don't think there are any Stearmans remaining in the
agricultural business. They have been replaced by specially designed
aircraft, many with turbine engines, which make more sense economically.

Nicely iPhoned, Jim. I gather that the Stearman was a little under-powered in its
original fit, so doubling the power might make it a fun machine to fly – once
you had countered the extra swing on application of power . . .

I saw this airplane fly a tight pattern and land for fuel, so I wanted a photo.
According to the pilot, it is a recently finished restoration, 11 years in the
making, and sports a Pratt & Whitney R-985 of 450 hp instead of the original
225 hp.
