Hi mate, can you share your thoughts about your FASST compatible receiver? Does it hasve rssi output? How far can you fly without failsafe issues? Many thanks!

elchue Mar 23, 2018

Hey mwm8X8, the RX works good with my Futaba T14SG in FASST-MULT mode. All channels (14) will be transmit in S.BUS, in datasheet they written only 8ch.
On rcgroups you can find a thread about IRangeX FX801 receiver, it looks exactly like FM800 Pro and they had found an RSSI on the chip.

I had tested it with BF 3.3.0 on this FC but whitout good results and so i removed this wire. I didn't test it anymore.
About the range, i only flown on Tiny Whoop already on sight without failesafe.
FM800 (non Pro) has short antenna wires on board exept detachable antenna.
I think the range is more than enought with this receiver.

update for range: possible 500m, not flown farther but possible

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
