Here you'll find links to the best performing products for tinywhoop drones based on my testing over on AOS Labs and my own experience and research. Some of these links are affiliate links (affiliate policy).
Motors
HappyModel SE0702 23000/26000/28000KV
HappyModel have been making great Tiny Whoop motors for quite a while. This smaller 0702 size offers great power at a light weight. Choose 23000KV for efficiency and 26000KV for power on triblade props.
RCinPower 0702 27000/29000KV
Well made, lightweight and very powerful. The high KV of these motors prioritises power over efficiency.
RCinPower 0802 22000KV/25000KV
These 0802 Motors from RCinPower offer great performance but at a slightly higher weight than the 0702 size. Perfect for slightly bigger 35-40mm props. In my testing the 22000KV option performs best on triblade props.
Electronics Stack
BetaFPV Air Brushless G473 5A 5in1 AIO
A super lightweight AIO flight controller from BetaFPV with all the features you need including 16MB(!) of blackbox storage, a modern gyro chip, and a decent VTX that puts out up to 400mW of output power and is SPOT ON on the 25mW setting. The 5in1 integrates a 2.4GHz ELRS RX on a UART. If you fly ELRS it's hard to argue that this isn't the best 1S AIO you can buy right now.
BetaFPV Air Brushless G473 5A 4in1 AIO
A super lightweight AIO flight controller from BetaFPV with all the features you need including 16MB(!) of blackbox storage, a modern gyro chip, and a decent VTX that puts out a good amount of power (but a bit more than 25mW on the 25mW setting!). You'll need to bring your own receiver, although BetaFPV have also promised a 5in1 version with an integrated ELRS RX coming soon.
Flywoo GOKU F405 AIO - F405 FC + 12A BLHELI_S 1-2S ESC w/ ELRS 2.4GHz Rx (MPU6000)
My favourite tiny whoop flight controller. Blackbox, 2S rated ESC, ELRS 2.4Ghz UART receiver. The F405 processor has plenty of flash space for future Betaflight versions and enough processing power to run a 4K PID loop. It has a plethora of UART connections for digital or analog VTXs and it's super small and light!
JHEMCU AIO Board - GSF405A F4 FC + 5A 1-2S ESC w/ Built-in ELRS 2.4GHz Receiver
This is a fantastic tiny whoop flight controller for up to 2S batteries. It has blackbox and a UART ExpressLRS receiver built in as well as all the necessary connections for digital or analog VTXs. A great feature set for a tiny whoop!
Happymodel ExpressLRS F4 5A 5-in-1 AIO FC w/ Built-in 2.4GHz Rx
1S Tiny Whoop flight controller with built in ExpressLRS receiver. No blackbox chip is a limitation for tuning.
Happymodel X12 AIO 5-in-1 Board - F4 FC + 12A ESC
A fully featured AIO flight controller for Analog toothpicks up to 2S battery voltage. Includes ELRS receiver and 400mW OpenVTX analog video transmitter. No blackbox chip will limit the ability to tune the drone however.
VTX
HDZero Whoop Lite
A smaller and lighter version of the HDZero VTX. It uses a super lightweight camera and runs on up to 3S battery voltage
Happymodel ELRS Fyujon V2.0 AIO Board - 5.8GHz OPENVTX + 2.4GHz ERLS RX
An all in one 300mW VTX and ELRS 2.4Ghz receiver. If your flight controller doesn't have this build in it's a great solution for tiny drones and weighs only 2.1g!
Walksnail Avatar 1S VTX
A smaller and lighter version of the Avatar VTX. There is a version with the standard Nano camera and a LITE version with an even lighter board and camera. It only works up to 5V though so you'll need a 5V 2A BEC if you're running 2S batteries!
Receiver
Happymodel ExpressLRS Nano 2.4GHz EP2 RX
Happymodel were the first to bring out ELRS hardware and their EP2 receivers closely follow the developers reference design and are incredibly tiny. If you need the smallest size and weight at the cost of some range the EP2 with the ceramic antenna is the one you'll pick.

Batteries
DogCom 1S 320mAh 75C LiHV BT2.0
DOGCOM make a lot of excellent batteries and this 1S 320mAH LiHv is no exception. It's available with a PH2.0 or BT2.0 connector. The BT2.0 (GNB A30 compatible) connector is the best for Tiny Whoops right now.
BetaFPV Lava 1S 260/300/550 mAh
This is a folded cell battery from BetaFPV with great performance for the price. All of the top performing Tiny Whoop 1S cells are using the Z-Fold technology and it's great to see BetaFPV taking advantage of it as well. The cells come with BT2.0 connectors and will also work with GNB A30 connectors as well.
GNB 380mAh A30 1S 90C
Awesome power density at the cost of energy density, great for high performance tiny whoops!
Newbeedrone Nitro Nectar Gold 300mAh
Excellent performance across the board with the least voltage sag under load. 40C? Proof that C ratings are meaningless!
GNB 350mAh A30 1S 70C
Excellent energy and power density but with a little more voltage sag. An all around excellent choice.
