propeller type and performance

Post Zacke »

Hey guys,

are there any differences between the two available propellers performance wise? I'm going to use the MT composite propeller. But does it meet the performance data given in the manual or are they for the McCauley?

Thanks in advance,
Zacke

Zache,

Good question. The MT and the McCaulley props are almost identical in performance until 2,400 RPM. That's when the MT just moves ahead. I think we measured somewhere around 200ft/min greater climb rate with the MT when at max 2575 RPM. We attributed this to the scimitar blade design and lower drag on the tips.

Hello again,

are these performance and wear differences simulated or is it just the difference with the vibration? Background: I'm used to have the MT Propeller because it looks much more modern. But I'm going to use a new repaint for my Comanche with an quite old style colour scheme and the MT doesn't seem to fit optically here.

Thanks in advance,
Zacke

That's a good question Zach, we don't wear the internal engine parts more based on vibrations but perhaps we should. We had a McCaulley aluminum prop on our Comanche 250 and later replaced it with an MT wood / composite and the difference in vibration was big. Roughly 1/2 the vibration intensity. And it makes sense that the crankshaft bearings would last longer with less vibration, along with many other parts that are sensitive to it. We will add this to the core physics engine for a future update, thanks for the post.
