Frank: There isn't any 424/426 racing in our area (North Texas) BUT, we DO have a very active Q-25 and EF-1 series. Q-25 is just 424-legal airplanes with an OS 25FX or Magnum 25XLS on the front. We have our first race of the season THIS SUNDAY at the Richardson RC Club field. Visit the North Texas Pylon Racing Organization (NTx-PRO) at http://www.ntxpylonracing.org/ and come on out and join us this weekend.
