Hi everyone, I am building An RV7 and have read a multitude of threads regarding the differences and benefits in these two props, and my question is:
Which prop would be better cg wise if I am using the parallel valve Aerosport IO-375 8.5:1. From what I have read I sense that the 7's tend to be tail heavy, and do not want to limit my baggage capacity, that's one reason I wanted the 7.
Is the WW too light?
I like the speed from these two props, BUT -
I am still unsure if I should not just go with a straight aerobatic prop with counter weights. I have a lot of aerobatic experience in Pitts and Extras, and do plan on light to medium aerobatics - no snaps or tumbles, but plenty of hammers and some inverted and negative g like a pushover humpty or such. Even with an inverted oil system, there may be moments of very low oil pressure. Has anyone experienced momentary high RPM's on hammers or holding an inverted line for a few seconds or pushover humpty?
All advice is appreciated!
Thanks, Damon
