 |
|
I've got a chance to purchase a brand new Hartzell constant speed that's
been in the box for four years for $4,500. Standard 80" blades.
Van's has a new Hartzell prop with blended air foil type blades for $6,300.
Anyone out there know if the difference in performance between the two
is worth the additional $2,000?

Randy would be the person to ask this to. He has the non-BA prop because it wasn't available when he purchased. I think he said it is a knot to a couple of knots max difference. How much is a knot worth? If you search the archives you should find a post from Randy on that, if I remember correctly. Also remember that you get a new BA for $6,300 that has just been built, hasn't been sitting in a box for 4 years.
Bottom line, there is a difference, but you would have to search the archives to find out better info on how much unless Randy is still reading this (he pops up his head every couple of months).
do not archive because it should all be in the archives already

Thanks Jesse, but there are those of us who haven't had much luck with researching the archives over the years. In fact, none. This is my second RV. Thanks for the info though.

Here's a post from Randy a long time ago.
I talked a litte with Van the first day I flew and he mentioned the
prop. He said that the blended was 2 to 3 mph faster. I told him the
older prop was a cost saving item. Randy
