F3F models are fairly demanding in terms of programming (if not quite as complex as F5J or DLG!). Aside from having four-servo wings there are ergonomic and trimming considerations which need to be taken into account, especially for competition work.
Over the years, I've competed in over 140 F3F competitions [as of Feb 2025] and programmed a variety of radios for this task. These include the Futaba FF7 Super, MPX 3030, MPX 4000, MPX Royal Evo, MPX Cockpit SX, Futaba 12FG and FrSky X9D+ running OpenTx. More recently, a FrSky X20 running Ethos.
