Calling all 70mph+ 21 rigger guys,
What's the fastest repeated speed you have seen from an Octura 1450 with standard Leading Edge pitch in a heat race boat? And can anyone else on here verify it as legitimate? I'm looking for real speeds please - not keyboard warrior stuff or very light SAW specials. PM's are fine if it's not to be made common knowledge.
Why? I'm trying to establish some mathematical detail based on this prop in order for me to learn more about props, so I'd appreciate honest numbers. Diameter and any other info that may be relevent may be useful, but not 100% essential. At the moment I'm primarily interested in peak speed vs Leading edge pitch.
Why 1450's? Very common prop in my favourite class, 21 riggers, and they have to really work well to obtain their speed compared to bigger engines.
