User Manual

- UART3 is used for Serial receivers: SBus, SumH, SumD, Spektrum1024/2048, XBus.
- UART2 used for Telemetry: Smartport.
Cleanflight and Betaflight can send Smartport telemetry to the FrSky X-series receivers over a
single wire. Connect UART2_TX port to the S.PORT pin on the receiver. It only takes one wire
because the ground connection is already made with the SBUS cable.
The voltage divider for LiPo monitoring is built into the Furious FC. To enable LiPo monitoring
over Smartport: Enable VBAT and Telemetry on the Config tab Select Telemetry -> SmartPort
and AUTO on the ports tab Set telemetry_inversion=on in CLI (This is the default in later
firmware)
The LiPo voltage shows up in OpenTX as VFAS. The most useful telemetry parameters for me
seem to be VFAS, RSSI, and RxBt (receiver input voltage).
- UART1 is used for OSD.
iii. Configure Receiver (configuration tab)
- PPM and SBus connect directly to the RX port (5) on Piko BLX FC boards. You must solder the
jumper on the board for either SBus or PMM when using this type of receiver.
- Satellite receivers plug into the JST connector.
See Appendix 1 or 2 for more information about connecting your Furious mini Rx (SBus) or
Spektrum satellite.
iv. Choose model/mixer (default is Quad X) (configuration tab)
v. Configure transmitter, set channel mapping (receiver tab)
- Configure channel reverse switches, mid and endpoints (1000-2000) and trim channels
on transmitter
vii. Ensure ESC calibration matches ESC configuration, recalibrate ESCs if needed (motors
tab)
viii. Learn about flight modes and configure channels/switches to activate them as
required. (modes tab)
ix. Learn how to arm/disarm
x. Bench-test failsafe
xi. Read safety notes
xii. First flight should be in Acro/Rate mode (the default mode when no other modes are
active).
