I did my CFI with them in 1998. At that time, you needed to arrive with your written and spin endorsement done. It was a five day program in an Arrow, then a short flight up to Champaign to do the checkride with a DE. It was a fair checkride with no tricks, surprises, or FSDO BS.
I could tell you a couple of nightmare stories about two different FAA inspectors at two different FSDOs. Hence my trip to St. Louis and satisfaction with Skylink. If you get out there, tell Herman I said hello.
