hey guys, i was just reading over a spec sheet that i derived from the POH out of the Geronimo that I fly from time to time and was relishing how much I enjoyed flying that aircraft and want to know what aircraft y'all best enjoy.....my obvious choice is the Geronimo, afterall, I earned my multi-commercial ticket in her. biased? maybe, but I love her! here's the spec sheet I came up with for my checkride and to remind myself about her....(you DO go over this material for the planes you fly, right?)
