A question for those of you flying with an AOA or LRI installed in your 701:
how useful is it? It would seem that in the 701 (with lift to burn) it would
be less important than in a more conventional aircraft.

My EFIS has inputs for an AOA probe. But the wings are closed up so I'm
wondering if it is worth the trouble to install and plumb a probe.

I installed the Ohio LRI in my 701. It is bent back to a riduculous
degree and I still don't have it calibrated to stall at the Red/White
line. I like having it, especially in steep, slow turns and such
maneuvers, but it certainly isn't necessary in such a high lift design.

I built one up from a rod of plexiglass using a long drill and a sensitive air gauge, and trialled it for a few flights.

I had to set the probe at a much lower angle than expected, and although it operated as supposed to I really wouldnt want it on my 701.

There is such a wide envelope of airspeed and AOA available and I dont see the gauge has any compensation for A/C weight and flaps down conditions, these variables have a huge effect on when and where the plane ends up.

I'd like to be more specific but having tried it out conclude its best left out of the 701 / 801 cockpit
