    Hello, It has been my experience that the 1956 - 1959 Cessna 172 straight tails (especially the 57 model) take less ground roll (as much as 400 feet) than the early 60's models when they first introduced the swept tail. All have the 0300 engines.

    Other than the swept tail the main difference is that in 1958 the landing gear was moved aft by three inches. Any one else experience this or is it just the particular planes that I happen to fly. Engine time has been about the same on each plane.

    earlier ones are probably lighter

    They had less equipment installed, and a lesser profile drag.

    I wonder if there might be a more favorable CG in one vs the other, that reduces the drag induced by the horizontal stabilizer.

    It very well could be. I'm comparing a 1957 to a 1960 mainly which both have about the same weight.

    Prop pitches? Rigging differences? Venturis? Wheel pants? Empty Weights? CG?

    There's a lot of factors to consider.

    One could have a climb prop and the other a cruise prop. That would be very noticeable in ground roll.

    Both planes have the same prop, same venturis, took the wheel pants off of both, empty weight almost the same and as far as I know the cg is the same. I have flown several 1957 and 1960 models and always get off the ground better in the 57 over the 60.

    Welcome to PoA! Where are you located in Georgia? I'm assuming that's the state and not the country...

    Thanks for the welcome. Yep the state. We are in the Northwest Georgia mountains.
