I estimated/measured from the attach angle to the rear of the HS to get approx. 13". A 1/32" drop over 13" run amounts to about a 0.138 degrees decrease in your angle of incidence. I am not an engineer, so I don't know if this matters, but I do figure that if it does, then this will likely be the least of my worries while working my way to a finished RV-9A. 1/32" is about the thickness of the pen marking line on the attach angle isn't it? Hope this helps. Comments from others builders and engineers are requested and welcome.

The reply was, in so many words, that it did work but was not nearly as effective as a good whip.

Initially, without the wheel pants and leg fairings I could not get the prop up to redline (2600 rpm) in level flight. After I put the fairings and pants on it will redline in level flight after a few minutes but just barely. This makes it a good choice for a cruise prop and climb performance is just fine. Top speed is 160kts but since it also burns over 9gph I have been trying to fly around at 2300 to see how that works. Speed is about 135kts and fuel burn is closer to 8 or maybe even a little less. If you put a little work into the metal spinner it will polish up and look very nice. BTW: since the 9A sits about level on the ground as opposed to the 6A which is somewhat tail low, getting onto the wing without the step would be rather difficult-especially for us old guys.

Being that the horizontal is attached to the fuse with shims, you would simply adjust the thickness of your shims as needed. Looks like I was concerned over nothing. Thanks to all that responded.

They include connectors, crimper, pins, etc.. Price is $55.00 http://www.steinair.com More "Stuff", less money! Cheers, Stein Bruch RV6's, Minneapolis. Do Not Archive
