I see there are a lot of Falcon fans here. I have a lot of props for my various engine setups because for what I want out of a prop, most of this data is not useful. We have noise issues at a lot of fields up here and even though a Falcon 25x8W on my DA-70 might be a good performer, it is way too loud in the air. Vess props are usually out right away, even though they too are good performers.
The motor I have the most props and effort on is the DA-120. I have had it on cans, RE2, and now ES pipes. Each combo likes different props. Most of you don't try this many props, and most of these were bought for the noise requirement as this has gone on for 4 seasons now.
Falcon 27x11, 29x9, 29x9W
Biela 29x10, 27x10x3
Vess 28B stealth
Mejzlik 28x12, 28x10evo, 29x10evo, 29x10s, 27x12TH, 27x12THx3, 26x10THx3, 26x12Nx3
At the moment I like the 27x11 because it is a good combo and it spools very fast. For IMAC I like the 29x10evo for what I do, but the 28x12 is actually the better prop in the more advanced classes. 3 blade I like the 27x12TH, but my IMAC friend likes the 26x12N.
The Falcon 29" props rip a lot and the evo is a much quieter prop.
