I had the opposite experience. I felt like the 4 blades (in general, no the ProET specifically) could be ran higher. I theorized it was because the blades were typically a little shorter, so they didn't begin to pierce the surface until you jacked the motor a little higher. My 3 blades found a sweet spot just a little lower - maybe 1/8" to 1/4" lower. 4 blade should have a better bite....at any given time with a surfacing prop, there's at least 2 blades fully submerged in the water. With the 3 blade, at some point during the rotation, there may be only 1 blade fully submerged in the water.
Yes i do agree with that also its prop dependant for sure. I guess its just been the props ive been running in 4 blades like trophy's don't like to high if there stock I find. Above the pad for instance. The only 4 blades that ive had that liked above was the drag4 really. The older Trophys and Hydros ive tryed like no higher than even but 1/4 bellow they all were great also. My chopper 2 and drag3,ET,mazco moded to offshore cut could all go above and some higher than I wanted to go and still chewed. Maybe thats what I based it on only. What I said was a pretty blanketed statement perhaps. Then again there are still variables like setback driver weight and so on that come into play. oh ya and balls.:big grin So really what works for some may be different for others for sure. That reminds me of an old saying JR used to always say. You cant try to many props. That's for sure!! Theres a lot of 4 blades now that have larger dia than the old ones used to have. I havent been running any of the new 14+ dia 4 blades. Been running 14 1/2 3 blade for a few years now. I gota try some of the new stuff like the new and improved XoB for instance in a 27 please.:big grin
