Well, if you hook it up as labeled, it works just fine. The vario is not TE compensated, though. The airspeed should have been correct. Sometimes, you have to think back and forth between MPH on the SFG, and Knots on your ASI.

I have one sitting on my shelf, too, Frank. If you don't think yours doesn't work, you could always send it to Steve's Home for Wayward Glider Stuff. :-)

Steve - I have to correct myself he the TE was plumbed to Static and I think that will throw off the ASI.
