Flywoo GOKU GN405 Nano HD 35A Stack V3 w/ TCXO ELRS 2.4G
Rs. 6,999.00
Specifications
| Part number | FW19003949 |
|---|---|
| Weight (g) | 6.5 |
| Dimensions (mm) | FC 25 x 23 x 8, ESC 27 x 33 |
| Cell count | 2S, 3S, 4S |
| Voltage range | 2-4S LiPo (limited by the ESC; the FC alone takes 2-6S / 7.4-24V) |
| Mount pattern | 16 x 16mm, M2 |
| Stack size | 16 x 16mm |
| Frequency | 2.4GHz (ExpressLRS) |
| Output power | ESC 35A continuous; FC BEC 5V/2A and 3.3V/0.5A |
| Compatibility notes | Mounting is 16 x 16mm on M2 - this is a nano stack, not a 20 x 20mm one. Some reseller listings label it 20 x 20mm incorrectly. Flight controller (GOKU GN405 Nano HD V3): STM32F405 BGA, ICM-42688P gyro, DPS310 barometer, 16MB blackbox, USB-C, 6 UARTs (UART5 SBUS, UART6 the ELRS receiver). BEC 5V/2A and 3.3V/0.5A. 3g. No OSD chip - this board is built for digital video only, so it will not overlay on an analog VTX. Built-in TCXO ExpressLRS 2.4GHz receiver. Direct plug-in for the DJI O3 and O4 air units. ESC (GOKU BS 35A V3): BB21F16G MCU, 35A continuous, accepts PWM, OneShot125, OneShot42, MultiShot and DShot150/300/600. 3.6g. The FC/ESC pin header takes either a QUAD or a HEX ESC, so the same flight controller can be moved to a 6-motor build with the HEX board. Watch the voltage: the flight controller is rated to 6S but this 35A ESC is 2-4S, so run the stack on 4S maximum. |

The Flywoo GOKU GN405 Nano HD Stack V3 is a 16x16mm nano stack for small digital builds. The GN405 Nano HD flight controller has an STM32F405, ICM-42688P gyro, barometer, 16MB blackbox and a built-in TCXO ExpressLRS 2.4GHz receiver, and plugs directly into DJI O3 and O4 air units. It is paired with the GOKU BS 35A 4-in-1 ESC.

Compatibility
- Frame: 16 x 16mm nano mount only - not 20x20 or 25.5mm. Check your frame has 16x16 holes (some resellers list this stack as 20x20 by mistake).
- Battery: 4S maximum. The FC handles 6S but the 35A ESC is 2-4S.
- Video: digital only - no OSD chip, so no analog overlay. DJI O3 / O4 plug in directly. The BEC is 5V 2A only, so an O4 Pro must be powered from VBAT.
- Radio: built-in ELRS 2.4GHz - pair with any ExpressLRS radio.
Works with (available at AeroFlow)
- Radio: RadioMaster Pocket (ELRS)
- Motors (3"): GEPRC SPEEDX2 1404, RCinPower GTS V3 1404.6
