I have the artf version, had one flight on saturday which you know was a cold and windy day, im too impaitent. The wheels are completely free, no spats, i probably have to fly it off the deck rather than the 3-6 feet takeoff i am used to with a couple of my electric models. What do you have powering yours? Mine is running an Irvine .53, having a few probs starting it though.
