Da Rock,
If you really want to see what your plane is stalling at, you can get
http://www.eagletreesystems.com/Plane/plane.html
I have an early version, and have used it in a"troubled" plane. I helped me in tuning my Ultra Stick. It is was both stable when you were gentle with it, and snappy when you wanted it to be when I was done with it. (I used past tense because I had dumb-thumbs and augered it in one fine morning)
I do not have the live feed, so I have to take a few runs, hook it up to my laptop, and analyze the data.
With the Eagle Tree Systems Flight data recorder, you don't have to guess what the plane is doing... It's right there. Graphs of flight speed, stick inputs, artificial horizon, altitude, and rate of climb, etc.

I really don't care what exact speed any of my models stall for a very good reason. I'm no better at seeing exact speed in the air than any human. And since the winds encountered are a complete unknown, and almost always present, it's pretty much a waste of time to know the exact speeds.
Changes in stall speeds aren't going to be great. Matter of fact, the changes in speed possible aren't going to be great enough to actually be significant enough to be useful. But it's really fairly simple to tune elevator throws to fly the model significantly safer on low rates and energetic enough on high rates.
I really don't care if a change will theoretically increase the stall speed from say 16mph to 18mph. Almost nobody can tell the difference in those two speeds in real life. And while attempting that fine a judgement, figure out what the wind out in the approach area is and what it's direction is and what that combination means to the 2mph improvement. We can't see speed, or wind, or the difference in AOA that spells stall well enough for any of the numbers to matter. So I basically don't use them beyond finding the safe range for a CG for the maiden. Or to check CG changes later when I'm sorting the airplane.
But for people who like to know all the numbers, it's really kewl that we do have apps and hardware that give 'em to us. Thanks for the link.
