YES! The 260 Pawnee with constant speed prop is ear shattering. When I
towed with it I always reduced prop RPM just after liftoff and, after
glider release, I reduced to the bottom of the green arc, about 2,200
RPM as I recall. I towed with a 235 Pawnee at Black Forest, about
1,000' higher than Moriarty, and it towed just fine. I also towed with
it at some 8,500' airports without difficulty.

We will be purchasing an additional PA25 for our club, and like many other facilities noise is becoming a bigger issue. Our current Pawnee has a 235 HP motor which has had the 250 HP STC (domed pistons) with a fixed pitch prop. The STC has performed well with far better climb performance when towing heavy glass 2-seaters. My question is whether a 260 HP Pawnee with a constant speed prop is louder that the 235 fixed pitch prop? I have heard this rumor, but have never been able to verify it.

Any and all input is welcome.

That Pawnee sounds like the trumpets of Jericho, loudest tow plane I've ever been around. If you want to **** off all your neighbors, get one.
