My opinion of the 172 / 170 conversion, the 172 has a much better instrument panels 6 pack instruments, a vac system, center stacked radios, and a larger fuselage /windows.
but when converted to tail wheel they are squirrels, when the gear boxes are moved to the front some thing happens to the CG. They just don't handle well on the ground.
The 170- has three versions, the 48 rag wing, the 49-53 A and The 53 to 57 -B
all have small instrument panels that do not have space for a good instrument panel for IFR work.
radios are mounted low / left and are difficult to see. but they are a very good handling aircraft on the ground, and fly with a very light touch, most are 115-130 MPH aircraft.
They have very simple systems a 0-300-A-D engines that are easy supported, smooth to fly, and easy on gas.
I've owned 4, 2-48s 1-B and 1-A, my favorite is the 48, they are lighter, faster, and have a better useful load. there were only 712 of them made.
