A prop can make a world of difference... and sometimes it's NOT because RPM goes up. Larger props can spin a few hundred rpm lower and still put out more thrust, or USABLE thrust based on your flying style/preference.
I had a 22x8 MSC on most of my 50ccplanes... great prop... tried an NX 23x8 on the YAK and LOVED it... tried it on a Vision 3D and didn't care for it as much.
Prop design has a bunch to do with it too... narrow blades, wide blades, thick/thin blades, sharp tips, blunt tips...
Just overall sometimes you can feel a big difference in the air just from switching brands and staying the same size... You'll find a brand/size you like the most and seems generally the "best", but then if you don't try others, you may not find that perfect prop that that particular airframe.
I couldn't agree more......
I've got about 5 different props I've tried on my DA50 and G62 WH planes. Each one has different characteristics. RPM numbers really don't matter that much, it's all in how the plane performs........ and what I like, you may not.........
Some of the higher reving props are good in one area of flight, but may suffer in another.
I've got a 22x10 in the Mejzlik and Menz S brands. Those two props are as different as night and day on a DA50 WH Edge or Extra. Does that make one brand better than the other? No way.........just different.
It's just amazing how much different the plane will handle when you try different brands and sizes of props on it......The trick is finding the one you like.
Are my rpm numbers accurate? Don't know........all I use them for is comparing prop loads between different props, and it works fine for that.
