F3F is fast, competitive, and fantastic fun. The format is simple, yet it requires dedication and many hours of practice in order to do well in competition.
F3F is also unusually demanding on your radio control system. On the one hand, the transmitter must be simple to operate so you can concentrate on the flying. On the other hand, when testing a new model, the pilot should be able to make key adjustments without having to land each time. Experience during ten years of competition has convinced me that these are two critical requirements.
