I miss the o= ld flyrotary.  I'm still using an alternative engine, so you would thi= nk that the other discussion groups would have a lot of back and forth, pre= senting ideas and data; but, there was a certain magic in our old group tha= t was inviting and accepting of exploring stuff that most people seem to la= ck.  Most groups seem to be happily focused on which options they have= for seat fabric rather than sussing out some new anomaly they discovered o= r created in their building/flying endeavors.

I have 9.8 hours left in the fly off p= eriod of my Corvair powered 601XL.  I posted the message below to the = Zenith forum.  Nobody seemed to care, even though I found it quite int= eresting.  Nobody seems to have the taste for experimentation over the= re, I guess.
I've been spendi= ng a lot of time trying to nail down the Vx, Vy and=20 best glide numbers for N167EZ.  My methodology has been to have my Dyn= on D-100 record data while I fly sawtooth patterns, then analyze the data=20 with a spreadsheet I created.  Saturday was a beautiful data for the= =20 task.  Heavy, but high, overcast, with perfectly smooth air once I got= =20 over 2500.  I've been doing this a while, so I've gotten much better a= t=20 holding my airspeed.  Here is the plot of what I got on my outing.&nbs= p;
Within the data, I pulle= d out the center segment of a climb, averaged the speed and the climb rate.  Then I plotted all the segments. = The=20 horizontal bars around each point show how well I maintained the=20 airspeed, indicating the variance from the average. 
The best glide appears t= o be about 43/44.  Would Vx be about 46?  I=20 do get over the trees much better at my home airport if I keep it closer to 50 than 60.  Vy is 59?  What is one to make of the severe dra= ggy=20 bucket at around 64 on the climb?
I think the climb points= at 46, 54 and 64 will need to be redone.  Awwwh!  That means I h= ave to go fly again.  Poor me.  :-)
