Looking for a good app that'll work on a Droid2 phone. I have looked at a few but they seem to have something not needed or something missing. I have a 1972 Cherokee 180G. It has a max gross weight of 2400. Full fuel and me (230 lbs) it looks to be able to carry another 426 lbs. Will it really handle that. Elevation at my home base is 89 ft msl. The book claims cruise at 124 kts but 105-106 is more like what I see so it makes me wonder about the amount of payload.
