Hi Rusty,

Well, better reading low than high {:>). I plan on making my filter housing out of 0.016 or 0.020 2024T3 and see if I can use the housing as a plenum to boot. Just really hate fiberglass work - ugh! (No disrespect for you folks working with it - just not my cup of tea). I am still trying to get the dimensions on some of the "double cone" filters so I can work up the dimensions for the filter housing.

Weather looking good for tomorrow - provided you keep your rain there {:>)

Subject: [FlyRotary] Re: best climb, was: warp drive 3-blade prop

Have not tried higher angle of climb since new
prop and gearbox - but, I have found that 120 MPH was the best compromise
between climb rate and cooling with the old combination.

One other thing just came to mind while trying to figure out why my best climb speed is so low. The other day, I pretty much proved that my ASI was 15 mph low at 160 mph indicated. It seems even farther off as speed increases. It's probably safe to say that my ASI is at least 10 mph low at 90, so perhaps I'm really doing 100 mph. One of these days I'll figure this all out.

I'm off to spend the rainy afternoon in the hanger. Today's mission is to pull the cowl, and remove the giant, and un-necessary oil line that runs up to my oil filter bypass block. That will free up space for the filter that I got the other day. I hope to get a chance today or tomorrow to do some test runs on the ground with, and without the filter in the system. If I show that there's now significant decrease in power, I'll make a fiberglass housing for the filter inlet. I'm half hoping the filter is really restrictive so spare myself the agony :-)
