The RB-25/RB-25S builds on the success of the previous trusted Redundancy Bus Series by adding new advanced features combined with a compact new design which meets the needs of users who want a flight-safe system built in a smaller size unit.

Triple Receiver Redundancy & Dual Power Input
RB-25/RB-25S has been designed to offer both dual-power and triple-receiver redundancy. This provides the user triple receiver signal and telemetry redundancy by adding multiplex ports (RX1-3 IN / S.Port). Dual-power provides a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections. The dual-power consumption system is designed to operate in balance mode, where it consumes the power line from either power sources depending on which has the higher voltage.

Diversified Sensor Telemetry
The RB-25/RB-25S also works as an extensive sensor module with various built-in sensors including diversified telemetry. The RB-25S also includes the high-precision telemetry sensor for monitoring altitude, vertical speed, etc. can be also used as an alternative to using a GR or S series receiver.

Power Switch Function
The built-in power switch function draws the support of using multiple types of external switches (e.g. NFC switch, Pin Plug, etc.) that enables flexible options on how the power can be switched on/off without the need to plug/unplug the battery connections.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.

The best pair of work / workout / casual socks I've bought in long time! They're no show on all my sneakers, incredibly comfortable and they never move.

Perfect for my company's temporary needs
Color: Gray, Size: 72" wide, 66" Tall
My company ordered multiples of these dividers to separate desks in much smaller temporary space we had to use after our offices were flooded in August 2023. (Yeah, I know - just getting around to reviewing them now!) These fit the bill perfectly. Granted a bit of privacy so we weren't staring at the employee next to us. Easy to put together; excellent value.
