    Here is the HummingBird F4 Pro 1S: The second generation of the HummingBird F4 products. Compared to the 1st Generation, we changed the Gyro to Bosch BMI160 which is smaller and more reliable compared to the MPU6000. (It can't use the same firmware target as the 1st Generation HummingBird F4 1S.) We also changed the camera plug to have a JST 4 pin (OSD Signal, BeeSign signal, 5V, GND) so now you can either use BeeSign Control or BeeSign OSD (more explanation of the BeeSign is down below.) Also, we upgraded the propeller to the newest Azi Quad Blade 31mm Super balance Prop. Last but not least, we also optimized the layout and increase the high current layout trace to handle more power.

    BeeSign OSD uses Mark2 MCU to simulate an OSD chip. BeeSign OSD is used to communicate between the flight controller and the onboard VTX OSD (NewBeeDrone Mark 1,2,3 Series Video Transmitter). The BeeSign OSD protocol is a non-stop communication signal whereas the BeeSign Control is passive.

    BeeSign Control: Compared to BeeSign OSD, the BeeSign Control is a lighter version that only sends signal during VTX setting changes. Using BeeSign Control, the OSD signal comes directly from the flight controller.

    Although BeeSign requires a lot of information of the controller to go through one single wire, BeeSign OSD only needs a BeeSign signal wire, a GND wire, and 5V power to reach the Mark2 VTX board.

    Note: Beesign uses UART1 port. Do not use this port for other peripherals.

    Don’t think, buy

    If your reading this your thinking about it, just buy it. I have hammered mine and it still keeps on going. Good flight time and beta flight. What more can you ask for

    One motor dead on arrival

    Unfortunately it took a while before I could fly this drone because it came with a defective moyor

    Great tinywhoop while RX is alive

    One of the best if not THE BEST tinywhoop I owned, but there is this "RX will eventualy die" problem which hit me recently.
    RX just stopped working suddenly. It's either solder new RX or try do desolder and solder again RX chip.
    It's a pity since this tinywhoop is so great BNF.
    Newbeedrone should really address this problem.

    best 65mm or 75mm whoop.

    I got this whoop to race on Wooptopia2021, I was aiming to place on enthusiast but thanks to the Hummingbird F4 PRO I managed to land a position on PRO class, not 1 but 2 classes above what I was aiming for.

    I can't wait for this whoop to be back in stock so I can buy a couple more for Whopptopia 2022.

    Thank you NBD crew, always great products.

    really fun when it worked

    was really fun for awhile, then like others, repeat SPI rxloss upon arming. was told to re-seat chip with SMD station, but i'm not that skilled. eventually ESC for motor 2 started getting crappy as well. really enjoyed it, but now unusable. $80 is appropriate, 100 not. don't forget it's 1S. and it's really easy to kill 1S packs.
