    • designed for tiny whoops and tiny 1S quads
    • motors can be soldered directly to the board, it doesn’t use connectors
    • it has built-in RX, however the RX is only SPI Frsky (D8/D16 compatible). You can still hook up an external RX to this FC as it has a spare UART, such as Crossfire or ExpressLRS.
    • it has a built-in VTX with 250mW output power
    • Antennas for both RX and VTX are removable – there are two IPEX connectors, the smaller one is for RX (Frsky SPI) and the bigger one for VTX antenna. If you are not using the Frsky RX, you can leave that antenna disconnected
    • the solder pads are small but nicely spaced out, so it should be easier to work with than most other whoop FC out there

    Cool features of Flywoo’s own ExpressLRS RX

    • it’s almost the same size and weight as the Happymodel EP2, which is super tiny!
    • it has built-in WiFi for firmware flashing
    • Device Category is DIY 2.4GHz, Device is DIY 2400 RX ESP8285 SX1280.

    You can learn about ExpressLRS here.

    Procedure of flashing and binding are exactly the same as all other ExpressLRS receivers. You can learn how to do it in my tutorial.

    Closer Look at the Nano Baby Quad

    It’s basically a tiny whoop without those prop guards.

    Flywoo Firefly 1s Nano Baby Quad Size Compare Tiny Whoop

    Although the difference is not huge, it actually benefits flight performance tremendously. The Flywoo Nano Baby Quad is slightly more powerful than a tiny whoop, and more importantly, it’s super efficient. I am getting over 7 minutes of long flight time on 1S 450mah, and almost 10 minutes on 1S 650mah!

    It comes with ExpressLRS receiver (2.4GHz), so you can actually bind it to any 2.4GHz ExpressLRS TX module (even different brands), including the Happymodel and BetaFPV .

It flies great  as it is but both performance and longevity will definitely benefit from something more robust. I would probably replace it with something like the BT2.0 connector, since I also have quite a few LiPo with that type of connectors anyway.

    Flywoo Firefly 1s Nano Baby Quad Bottom Battery Holder

    The frame is a deadcat design, which means the front motors are further apart than the rear motors, so you don’t get the props in the camera’s view.

    The battery holder is 3D printed in TPU and it’s a perfect fit for the battery they sent me (the 1S 450mah). However it’s quite thin, and can wear out over time. Anyway I think you can replace it with just a rubber band.

    Flywoo Firefly 1s Nano Baby Quad Palm Size

    The Flywoo Firefly Nano Baby Quad (what a mouthful) is absolutely tiny and quiet, perfect for flying in small parks. But beware it’s still just like a tiny whoop, it doesn’t handle the wind too well.

    I think this quad is designed around flight time and efficiency, hence the use of two-blade props. Those props have 1mm holes , so make sure you get the right ones when buying spare. I do recommend getting some spare props as they can fly away in crashes, the fit on motor shaft isn’t super tight.

    Get spare props here:

    The bottom plate is quite thin, at 1.5mm. It does flex a bit when you try to bend the arms but it doesn’t seem to affect flight performance since it’s so light. It’s holding up well to a few crashes I had with trees and landed on grass.

    How To Setup

    FC Board Name: FLYWOOF411FR, pre-flashed with Betaflight 4.2.0. You can find the original CLI dump here.

    Cool thing about this quad is that the ESC’s are already flashed with BLHeli_S 16.80. I am not sure exactly which custom firmware they are using, but RPM filter is enabled out of the box, and possibly 48KHz too.

    To setup it up, first of all, bind the quad to your transmitter. Because I got the ELRS receiver, so I had to flash the RX to the latest version first with my binding phrase. You can learn how to do this in my tutorial.

    Device Category is DIY 2.4GHz, Device is DIY 2400 RX ESP8285 SX1280. For some reason when I flashed it via WiFi, it didn’t want to bind to my TX although it came back with “flashing successful”. In the end I had to flash it via Betaflight Passthrough for it to work.

    Once it’s bound and working (confirm in Receiver tab in Betaflight Configurator that the channels are responding to your sticks), you should make a few config adjustments.

    In the Configuration tab:

    • change PID Loop Frequency to 4KHz (it was on 2Khz originally)
    • change ESC Protocol to DShot300 (from DShot600)
    • disable Motor_Stop
    • change motor poles from 14 to 12 (tiny motors have 12 poles, and 14 probably won’t work well for RPM filter)
    • change arming angle from 25 to 180 (so you can arm the quad even when it’s on unlevel surface)
    • Enable RX_SET under DShot Beacon, as it doesn’t have a buzzer, this will help you find it after you crash

    In Modes tab, assign switches to Arm, Beeper and Flip Over After Crash.

    In OSD, choose whatever elements you prefer on the screen.

    That’s it! We are ready for first flight :)

    Great Qwad, great service

    Bought one, broke the ESC's, repair, then break the board from soldering attempt. Bought another one, came with a defect accelerometer. They replace it after video proof. Thanks Flywoo, will do business with you again.

    Fun with some issues.

    The first one I bought only goes to runaway after a 5-6 foot drop to concrete. I don't know what's wrong with it. I assume the AIO. Now it is spare parts.

    The second one I bought has been great! I crash it constantly. It refuses to die. The power cable has broken off the board a few times. It is a small joint so it is a PITA to fix. I'd like to see this improved.

    Other than that. I have a lot of fun flying this.
