The Aero Club put on a small cross country trip with about 7 aircraft in all. I flew a couple of legs in JGP but one from Tokoroa to Tauranga was downwind. That leg took us 29 minutes to fly 37nm, from engine start to shutdown. During the descent into the Tauranga control zone the GPS was showing a ground speed of 149knots, during the cruise it was about 135knots. Not bad for a 180hp 172M.
