The CrazyF411 ELRS flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 20A Blheli_s ESC(Bluejay firmware pre-installed) which could support 2-4s. Bigger Mosfet could support high to 20A currents would be better for 2-4S toothpick drone or long range FPV drone. And because the 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate and low latency, this flight controller is the one that all Race/Freestyle pilots needed.

Binding procedure:

  1. Supply power to the flight controller by plug USB, wait until the green LED on the FC is off, immediately turn off the power, and then repeat again the above steps. When the FC is powered on for the third time, the green LED light will start to double-flash, which means that the RX enters the binding mode
  2. Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lua from “TOOLS” menu of your radio transmitter. Then hit [Bind] to binding with the onboard ExpressLRS receiver. The green LED should blinking slowly first then turn to solid, that means binding was successfully. If the green led still keep double flash after binding ,please change Model Match tab value from “off” to “on” or from “on” to “off”

Receiver LED status meanings:

Green LED solid means bind successful or RC link established; Green LED double-flash means get into bind mode; Green LED flash slowly means no RC signal input from TX module; Green LED continuous flash fast means ExpressLRS wifi enabled.

Serves purpose and holds what it was intended to
Color: 2 Tier-Black, Color: 2 Tier-Black
I like it. Keeps things organized and handy in small kitchen. The attachable bin holding my brushes I put on outside of unit not inside as company pics show it. That bin only has one clip to hold it in place. This makes it a little wobbly if you want to place it on the outside like I did. I used 2 trash bag twisties to help tighten it into place. Doing this made it no longer lose and the inside area space larger to hold both of my soaps. Fits everything I need it to. I appreciated the little lever on bottom that moves for water drainage. My sink design doesn’t work for the other drainage design I found these to have online.

Great sink organizer
Color: 1 Tier-Black, Color: 1 Tier-Black
I've been searching seems like forever for something to make my kitchen sink look more organized and this caddy solves my problem!! I found a different use for the basket that holds a scrub brush since I don't use one of those. Nice design that fits my kitchen objects and no worries about removing a tray to empty water out. I used the adhesive holder to attach it to the wall behind the sink but one corner is peeling off, causing the basket to hand on that side. :( It would have been nice to have a replacement for that, but overall I'm pretty impressed with this thing!!

Best organizer with a water spout to keep them counter dry!
Color: Black - 9.25″, Color: Black - 9.25″
I am thoroughly impressed with this product. I tried a product that goes over the middle of the sink and it blocked everything off and would always fall off in a funny ways. I had no room for my pots and pans and started getting irritated with it. This is up and out of the way has a little spicket to drain off the water and as you can see I got all of my sponge and soaps in the same spot which is wonderful cleaned off my counter beautifully. I chose the color black to blend in with my black countertop and also to look nice and clean on the counter. One of the best organizers I have ever found for a countertop. It's sturdy metal so far seems rust resistant, but I haven't had it long enough to know for sure. Mobilize easily to clean. Fabulous little sink caddy. I highly recommend to those of you that like to be organized and keep your counter nice and dry, and still arrange things so that it can be out of the way.
