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.

Advanced Stabilizer 
The RB-25S offers an ADV Stabilizer function which is an upgrade over the original classical gyroscope stabilization modes. The ADV Stabilizer offers an advanced mode that provides more programmable stabilized channels and flexibility.

The classical stabilization mode has been enhanced with 5 additional stabilization channels, providing pin mapping to each channel in the multiple flight modes like Stabilization, Auto-Level, Hover, and Knife-Edge with an airplane model.

In the advanced stabilization mode, all the RB25S output pins are configurable for stabilization and additional advanced features such as File Sharing, Programmable Parameters, and Developer Access, etc.

CONFIGURABLE VIA ETHOS LUA SCRIPT 

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.

Very well made Oxford casual shirts.
Size: X-Large, Color: Sky Blue
I've ordered 8 of these Button-down collared, long sleeved Oxford shirts in eight different colors. I'm 6', weigh 195. And have a 44" chest and fairly broad shoulders. The XL give me ample room, plenty of shirt tail to tuck in. And are well made. The shirts have a nice soft feeling to them. If you wash them with like items, and dry them likewise, taking them out before the cycle ends and hanging them. You won't have a single wrinkle. The shirts are true to color, and true to size if you follow the size guideline. These are not tailor fit, but regular fit shirts. Fabric quality seems very durable and well made. There is no smell when receiving the shirts. No more so than buying a shirt at a retail store. They do come in a vacuum bag. The shirts are a little heavier than a poplin shirt and can be worn year-round. These are great casual shirts for jeans and a sport coat, or slacks. I like the quality and the colors. I also like the thickness of the shirts. All of the shirts I've bought, black, blue, etc, have white buttons. Which makes them more of a casual shirt. But well worth the price.

Good Material Thickness and Comfortable
Size: XX-Large, Color: Blakc
I picked up the J.VER Men’s Oxford Shirt, and it turned out to be a solid choice. The seam quality is clean and consistent, with no loose threads or uneven stitching. The material thickness is right where it should be for an oxford. It feels sturdy without being stiff. There was no strong smell out of the package, which is always a plus. After a quick wash, it was ready to wear. The stretchiness is subtle but helpful. It gives the shirt some flexibility without changing the classic look. The softness surprised me. It feels comfortable on the skin and stays that way through the day. Overall comfort is great, whether you’re wearing it for work or a casual night out. A clean, comfortable shirt that fits well and looks good.

Good quality
Size: 3X-Large, Color: White
The shirt fit great! True to size. Only issue for me, it would have been nice if it was longer to tuck in.
