Hello,
Few changes comes to RCFA. The most important is implementation of the Frequency-hopping spread spectrum (FHSS). This makes using RCFA radio system legal in most countries (including EU, US, Australia/NZ). The preffered frequencies are: 433/868 for UE and 915 for rest of the world.
Here's a demo fly path recorded with RCFA. It includes GPS Logger (red line), Real-time record (yellow line), Flight Area (rectangles). It is a free flight as I'm not a F3A pilot (yet - maybe). It is easy to calculate radio range which was about 450 meters in this case with about 95-99% packets received. Unfortunatelly it was hard to fly further because of lost of sight.

I'll send above kml on demand as a replay to order form at

I'm glad that one of RCFA's users has mounted a nice "beeper-station

Well done on that


Best Regards
