Anyone have a sense of the financial puts and takes between going w a 4 cyl RG vs a 6 cyl FG Think Cardinal RG vs 182 or Arrow vs Dakota/235…. I’d like to find something that can cruise at 130kts or better, and has a useful load of >950 lbs. 4 cyl RG gets me there at 10gph but at the cost of higher insurance and annuals. 6 cyl FG burns more gas 14-15 gph but figuring insurance and annual costs lower because of the extra drag. At 50-75 hrs/yr and $6 gas is it a wash? 250 hrs PPL/IFR but no RG time….
