F3F is the Formula 1 of slope racing. I've been an active competitor since 2002 and remain completely hooked (the fact that we fly in some of the most beautiful landscapes is just the icing on the cake!). During that time I've developed and refined the transmitter interface using two of the most flexible RC systems available at the time - the Multiplex 4000 and OpenTx.
F3F is also technically demanding. On one hand, the transmitter must be simple to operate so you can concentrate on the flying. At the same time, it should be possible to adjust certain key mixers without having to land the model. Experience has convinced me that these are two critical requirements!
