Much more informative compared to BackYard Flyer (which after the first couple of issues became more or less a glorified R/C catalog); I always look fwd to Steve Neu's PowerOn column and couple of others that cover (or at least used to) R/C and flight dynamics from a more technical perspective. Still, in the past year QF has also steadily moved into the catalog/magazine format, with reviews that are offering a little less insight and justifiable criticism. I've found some of the past articles in QF invaluable, and in fact the past couple of months I had bought up the complete collection from fellow modelers. I current subscribe to QF and FlyRC (that one has great potential imo).
