That is a factory stock prop, BTW. The Magnum has had = a much=20 different shape at the root than the rest of their line for several = years now.=20 ---------------- I read that in the archives, but it's still only one prop, to about 6 = that don't seem to work well. If I'm not mistaken, the prop that Tracy = tested was also a Magnum, and it was draggy at high speeds. I've also read of = a few canard types that seem to work well with the IVO, but I suspect = they're hiding a good portion of the root of their blades behind the fuselage. I'll have to make a decision on a prop before too long, and I'll be = looking hard again. My intention is to get at least a ground adjustable, since I don't know what RPM I really want to run at yet. =20 Cheers, Rusty 13B powered RV-3 (experimental aircraft)...Be Afraid :-) 1993 RX-7 R1...
