Ok, odd question for this board but I'm not having luck finding any data on my searches. Does anyone know what kind of performance differences, if any, there are between the Hartzell 4 blade prop and the McCauley Blackmac prop?

This is for the Conquest airplanes that had the TPE331-8 or -10's.

WestStar out in Grand Junction Colorado does alot of work on the Conquest. 970-243-7500 ask for Dave Girard or Joe Carr.

Ok thanks, I'll give them a call.

Your best source for unbiased conquest advice is going to be Caleb Taylor at Proflight. He would also likely recommend you speak to the guys at Corporate Air in Fresno. The guys at West Star and Yingling also deal with a lot of Conquests, but I would speak to Caleb over any of them. Caleb's number: (760) 929-9627

No real performance difference but they do seem to be smoother and a little quieter if that's even possible on a Garrett. LOL
