My flight instructor just leased a errrr emm... Cessna Cutlass 172RG ... Was thinking about getting my complex endorsement. Ive read it takes anywhere from 2-10hrs of flying to get it. Since the Cutlass has a much nicer panel in it than my Cherokee i'll probably take my IFR flight test in it also so i'd like to get familiar with it. Any suggestions on reading etc... Or is it as simple as spending a few hours with a CFI?
