I am tasked with finding out what a stabilator is and I don't mean the CONTROL SURFACE that everyone is familiar with, but something like a FLIGHT INSTRUMENT from the early days of aviation, say the 20's.
I have done some google searches but everything always pops up as the control surface.
I asked some mechanics as well and they can't recall such a thing.
Can anyone help me out? I figure there are thousands of years of combined experience here on the website, someone is surely going to know.
