First flights on N291DR

Yesterday I flew our first flights on our new test ship, N291DR. We are already geared up to mount on a RANS S-6S so it was pretty easy. Here are some pictures of the setup:

We need a better place to mount the display -- we have a RAM mount on the upper framework but that's hard to see. In any case, though, we did make a few important observations:
  1. Basic operation of the probe is good.
  2. Our altitude math is totally off. Need to figure out what's up.
  3. The air was quite turbulent and the ball jiggled a lot; maybe we need some filtering after all.
  4. For some reason, the wireless connection kept cutting out.
I was doing takeoff and landing practice, and using my store-bought ASI as my primary reference but every once in a while peeking out of the corner of my eye. From that quick observation, it does appear like the AoA and yaw information is pretty useful and sensitive and I could, if I wanted (and if the system were more reliable, and mounted more in my field of view) fly using it.

I'll be trying to fix our altitude math and then doing some post-analysis of the data in the coming days.
