Guest Posted May 27, 2017 Report Share Posted May 27, 2017 I have a 3 blade MT on my 400, it was 38 pounds lighter than the Hartzell I removed. It's been on for 5 years with no issues so far. Clarence Quote Link to comment Share on other sites More sharing options...
MyNameIsNobody Posted May 27, 2017 Report Share Posted May 27, 2017 Three blade McCaulley that works with Sabre's cowl mod. No complaints in over a decade of operation. Speed-130-160 knots 10LOP (depending on winds) Vibration-What vibration? Weight Penalty-935lbs useful load. Has not been an issue Service-Not yet overhauled. Hung in 13 years of operation. Climb-Over 1000'/Min pitched for 120MPH up to at least 4K (unless high density) Summary-Excellent! Decent/Slowing Down-Definitely does slow plane down with a pull of power. Like having a speed brake out front Ramp Appeal-Superior to a two blade (more from large bullet polished spinner than extra blade) Summary-Looks great Quote Link to comment Share on other sites More sharing options...
Boilermonkey Posted May 28, 2017 Report Share Posted May 28, 2017 If you operate from a dirt or grass field a three blade is a must. The additional prop clearance helps reduce picking up stones and FOD. 1 Quote Link to comment Share on other sites More sharing options...
DonMuncy Posted May 28, 2017 Report Share Posted May 28, 2017 I'm not sure which prop MT sells for the 4 cylinder models, but my MT (K model) is also 74 inches. 1 Quote Link to comment Share on other sites More sharing options...

You must need it when that thing is operating in the stratosphere. Quote Link to comment Share on other sites More sharing options...
xcrmckenna Posted May 29, 2017 Report Share Posted May 29, 2017 Honestly I am not big on the looks of a three blade prop, but if the MT is 20lbs lighter than the Top Prop I would grow to like it. And living in the mountains the density levels really start to climb come summer time. The added climb performance of the three blade would be an added bonus.

KSMooniac Posted May 31, 2017 Report Share Posted May 31, 2017 I'm starting to do some research on props. Looking at the spects the Hartzell Top Prop two blades and hub weighs 62-64lbs. And the MT three blade prop and hub weighs 46lbs. Is that correct? Or am I missing something? Yes, the MT is the lightest prop package available for our planes. I wish they had a 2 blade option for us. I've been happy with my 3 blade MT for many years now after some initial paint failures and associated warranty work.Sent from my LG-US996 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

The Hartzell 3-blade flies me around at 172 mph true at 9000-10,000 msl. So much for 3-blades being slow . . . Theoretical book speeds are one thing but apples to apples is another. Would be nice to know what mph true a 2 blade gives you also! Quote Link to comment Share on other sites More sharing options...

gsxrpilot Posted May 31, 2017 Report Share Posted May 31, 2017 Brian Lloyd put the MT 3 blade on his 231 for his Amelia Earhart around the world flight. I think he's leaving tomorrow. After a speed run to NYC and back, he's determined the MT is costing him a few knots from the original metal three blade. I'm not sure which one it is. So the MT has come off and the metal prop is back on for the big flight. Quote Link to comment Share on other sites More sharing options...

He's intending to be posting as he's flying as he's fully rigged up with Sat phone, data, etc. 1 Quote Link to comment Share on other sites More sharing options...
