Serial ELRS 2.4G RX
Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.
- Plugin and unplug the flight controller three times;
- Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
- Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
- If the receiver has a solid light, it's bound.
The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.
- Plug in your FC to your computer, connect to ExpressLRS Configurator instead of Betaflight Configurator;
- Choose target "BETAFPV 2.4GHz AIO RX";
- Flash using the BetaflightPassthrough option in ExpressLRS Configurator.
How to flash firmware via Wi-Fi here.
Features:
- Highly integrated FC with onboard brushed ESC, serial ELRS receiver, blackbox, and OSD—making it extremely convenient for building, using, and maintaining your drone.
- Onboard brushed ESC supporting continuous 12A current output (peak up to 18A), with Turtle Mode (flip over after crash) support, and compatibility with 1-2S batteries.
- Main controller upgraded from STM32F411 to the latest STM32G473, delivering a 55% increase in processing speed for a smoother and more responsive flying experience.

Instructions for use for Anti-turtle mode:
- 1. The anti-turtle function (also known as Turtle Mode or Flip Over After Crash) on brushedFC is used in the same way as on brushless FC. In the Betaflight configurator, go to the Modes tab, find “FLIP OVER AFTER CRASH”, and assign it to an AUX switch channel. Set the trigger range for the AUX switch. The factory default anti-turtle switch channel is AUX4.
- 2. If the aircraft crashes and lands upside down during flight, simply turn on the anti-turtle switch first, then arm the motors. You can then control the aircraft to flip back upright by moving the aileron or pitch stick. After that, turn off the anti-turtle switch and arm the motors again to resume normal flight.
- 3. Currently, this flight controller only supports the official custom brushed flight controller firmware from BETAFPV. The official Betaflight has not yet released this firmware, so please do not flash non-official firmware yourself!

Good find
Color: Stainless Steel, Size: Medium Size
Great quality, durable, easy to clean, light. Super easy to use. Love the color, really helps me see if I got it fully clean. Numbers are perfect size and not too dim/bright to read. Mine has lasted around 2 years with weekly use and have had no problems

Easy to use. Stays sealed. Stays charged.
Size: 12 Combo Travel Size
I had previously bought packing bags in a store — the kind the you had to seal and then roll/squish the air out of one end of the bag. It really took 2 people to remove most of the air. I took them to Mexico, and they were just OK.
I switched to these vacuum bags before our family ski trip. What a great purchase! This set includes multiple sizes, which worked well for both everyday clothes and bulkier cold-weather gear. They also fit well inside different size suitcases. One tip: Fill the bag, seal it shut, squish some air out, but then suck the final air out with the bag already inside your suitcase. You can "massage" the clothes and guide how the bag flattens out for a really efficient use of your suitcase space. The organization you can achieve is really impressive.
The bag material and valve is tough enough to not allow any air leaks. The red "glides" they provide make sure the seal is solid and easy to achieve. And the system is simple enough that I suspect that elementary kids or people with lower dexterity could operate it (my teens certainly had no issues packing themselves).
After returning home, I folded all the bag along their original fold lines, charged up the "sucky thing" (which still held 75% of it's charge after being used at least 20 times), and tucked it all neatly in our travel drawer, ready for our international trip next month.
Great value. High quality. I'd even go so far as to say they're fun to use.

Travel bags
Size: 12 Combo Travel Size
Perfect packing bags. I’m using them for a trip to Alaska. The pump works easily . I tested them out and the air retention is perfect.? They are not too thick and will not take up space. The material seems like it will hold up without ripping. I will be using them often. They come in different sizes which work perfectly with different items.

These are a travel must!
Size: 15 Combo Travel Size
We recently took a trip to Japan and South Korea with our 3 kids, and needed to bring all their clothes for 2 weeks, with as few suitcases as possible.
These bags were a life saver!
We were able to fit so much more stuff in our suitcases with these bags. I don’t know how we would have brought everything without them. We would have had to bring at least one, probably two suitcases more.
Easy to use - the vacuum is compact so you can bring it with you, but super powerful and works quickly. Remember to charge it after you use it for when you pack back up. But, you can manually push out the air as well if you’re in a pinch.
