List of brushless whoop/toothpick flight controllers

This is the list of brushless tiny whoop/toothpick style flight controllers with brief description and features list. You can compare them and choose the best whoop/toothpick type FC that suits your needs. The list contains only the AIO boards – flight controllers with 4in1 ESC.

A note on the prices – IC prices were skyrocketing in the year 2020-2021 and so were the prices for flight controllers. Most likely the prices posted here will be incorrect by the time you will be reading this article.

Types of the flight controllers

Whoop flight controller has a shape of the rotated square board with a 25.5×25.5mm mounting holes pattern. USB socket and motor sockets are usually located on the bottom side of the FC and are faced downwards. Typical whoop frames are designed to have this layout in mind so should fit into most of the whoop frames.

Toothpick flight controller has the same whoop form factor and should fit on the same mount holes. However it usually has bigger size, and might not fit into whoop frames. Toothpick flight controller often has separate solder pads for motor wires. USB socket is located horizontally flat. Toothpick type flight controllers usually have higher current output for motors, some flight controllers reaching even up to 45A.

You can see that different manufacturers are declaring different distance between the mounting holes. Typically it should be in the range 25.5 – 26.0 mm. This is due to misinterpretation and lack of unified standard. Originally this distance should be counted as 1 inch (2.54cm)

FC main parameters

MCU – modern whoop/toothpick flight controllers have F4 (F405, F411) or even F7 type STM32 microcontroller (MCU). Betaflight stopped supporting F1 and F3 MCU’s already, so they are not recommended for the new builds. F411 MCU has only 2 full hardware UARTS. Read more about Flight controllers MCU types here. There is new G4 MCU coming into the market, replacing the old F4 MCU.

OSD – having OSD in your FPV feed is really handy. You can see the current flight mode, battery voltage, current, battery consumption, warnings and even more valuable information.

Current Sensor – if the flight controller has current sensor, then you will be able to add the current amperage value indicator as OSD element in the FPV feed. Also you can have battery consumption indicator.

ESC amps – the max ESC amps shows how much power can whoop FC deliver to the motors. The bigger and the faster motors – the more amps you need to deliver.

Battery input voltage – shows what cell count batteries can be used with this flight controller. Modern flight controllers support 2-4S or even 2-6S.

Integrated receiver – integrated receiver eliminates the need of soldering the external receiver, greatly reduces the weight and complexity of the build. Usually built-in receivers are connected via so called SPI line, so directly controlled by the MCU. The biggest concern using the built-in receiver is the relatively short control range with some rare exceptions like ExpressLRS SPI receivers.

SPCMaker Whoop F4 25A Flight Controller

Whoop AIO board by SPCMaker supporting 2-4S battery input and capable of 25A output. It was the most powerful AIO whoop flight controller when it was released.

SPCMaker Whoop F4 25A FC has all the useful features – MPU6000 via SPI, Betaflight OSD, current sensor, inverted and uninverted RX inputs, RX2/TX2 pads and even I2C interface (SDA/SCL). SPC Maker flight controller has also programmable LED and Buzzer pads.

Despite the manufacturer stating that the board has motor sockets with gold plated pins, I think these little motor sockets can really melt under the full rated current 25A! And not talking about 40A… If only the SPC Maker would have made motor solder pads – it would have been the perfect board for power toothpicks (3-4-5 inch) and lightweight 5″ quads.

The first (and the only) whoop flight controller with Bluetooth MSP connection. You can connect this FC remotely via Bluetooth with the Betaflight Configurator. This board is designed for 1-2S tiny whoops, delivering up to 5A constant current to the motors. The Crossfire Nano or ExpressLRS receiver can be mounted directly on the board with pin headers. The weight of the board is 4.2 grams.

The things I might miss in this AIO flight controller are Current sensor missing and the USB socket could be optional (solder pads) for weight saving, as you have remote connection already.

Banggood: –

This flight controller is almost the same as HGLRC Zeus5 (see above) but also very different. HGLRC removed the Bluetooth connectivity and installed the integrated SPI FrSky receiver instead. The 8Mb blackbox and BMP280 Barometer were added also. This board is designed for 1-2S tiny whoops, delivering up to 5A constant current to the motors. Because of the integrated SPI receiver you get 2 full free UARTS. The weight of the board is 4.3 grams.

One of the first toothpick flight controllers in the market in the year 2019. At the date of the release it had a whooping 12A current output capability and could be powered with 2-4S battery. So the NamelessRC was the first to release so called “Toothpick flight controller”. One of the interesting features of this flight controller – it has all the solder pads doubled on the both sides for your convenience.

A lot of them burned up when flashed with the incorrectly detected BLHeli_S firmware with too little deadtime (should be 120).
