[Sticky] FrSKY Redundancy Bus-10
Frsky have developed redundancy functions into a new smaller unit easier to house in your model. Its unique switchboard module will operate 2 receivers and 2 batteries to provide you with total peace of mind when flying your model. You can also run your servos from the switchboard with complete protection from high voltage overload. The Redundancy Bus also supports Smart Port telemetry for your Taranis/Horus and will provide telemetry feedback for voltage and overload indication.
- Recommended input voltage range: 4-8.4V
- Number of servos: up to 8
- Operating temperature range: - 20~75°C
- Weight: 10g
- Dimension: 63x27x10.5mm
- Overload protection on each channel and RXS
- Dual power dual receiver double guarantee (connect up to 2 batteries and 2 receivers)
- 50Hz mode of servo outputs (20ms period) or equal to the input of SBUS cycle
- Integrated S.Port telemetry feedbacks (including voltage, overload indication, etc)
- Servo signal output period settable
- High voltage servos supported
- Compact size and firmware upgradable

How to update the firmware on the RB-10:
My RB10 needed updating as the servos weren't working despite both RXs and RB10 showing green lights. Tried to update from Horus 12 but despite having the correct connections in place it just wouldn't flash so had to use the STK instead. Everything now working OK.
On a post I read somewhere that it's not advisable to use both internal and external modules at the same time. I want to use the RM9 extl module together with D16 on the intl so that it gives me redundancy on signal frequency . Will this be a problem?
The answer is yes, you can use the internal module with the external R9 module for redundancy. You can see a video here of someone doing this.
Great, thanks for the update.
I just bought a pair of RB10, my setup to my PC9 35cc plane will be like this:
- 2 life batteries @1450mah
- Rx1: R9-SX (900 mhz)
- Rx2: R-XSR (2.4 ghz)
- Horus X10s express
- Servo hitec 645 & 635 (stall current draw: 2.5A)
1. After I flash the RB10, should I flash both receivers directly to my Tx one each other, or can I just flash both receivers through RB10?
2. Is there any issue with Hitec servos?
3. If I need 10 channels, should I use an sbus to pwm? Or what the best option for that?
Thanks for any help.
My first quesstion is, why would you go to all that trouble and expence, and end up with a single point of failure?? (The RB10)
You have what is called "A single point of failure" If the RB10 fails you have no control.
There are also issues with the S-Bus decoder and non digital servos.
Maybe drop me a line on email@example.com, and we can discuss in greater detail.
