BETAFPV Meteor75 Brushless Whoop Quadcopter (1S HD Digital VTX)

Bullet Points

• Powerful propulsion capabilities combined with Walksnail HD VTX or HDZero VTX give pilots an immersive flight experience and impactful visuals.
• Ultralight weight for 40.5g (Walksnail)/ 36.4g (HDZero). With BT2.0 connector, it effectively decreases internal connector resistance for good conductive performance.
• Equipped with 40mm 3-blade props and upgraded 1102 18000KV motors. The upgraded motors not only take abilities as good as before to provide strong propulsion in 1S whoop drone but also come with a new look. And simultaneously its black and red motor bell fully matches the Meteror75 frame.
• Reserve two UART ports on F4 1S 5A FC(SPI Frsky) V3.0 board. The Frsky version also can be used as the PNP version. Therefore, pilots can connect the external receiver to it.
• F4 1S 5A FC (Serial ELRS 2.4G) V2.0 is flexible in upgrading and has great potential. It supports being upgraded to ELRS V3.0 separately without flashing Betaflight flight controller firmware.

Please make sure that the battery voltage must be 3V at least when flying, otherwise, the HD digital VTX would stop working. 

HD Digital VTX System

There are two HD versions to choose from. Based on Walksnail Avatar, the Walksnail Avatar Mini HD VTX also uses H.265 high-efficiency video coding, an industry-leading technology, providing 1080P/60FPS image recording with 22ms ultra-low latency. It is specially designed for 3.1-5V power input and 10g lightweight, which is compatible with 1S whoop drone. Build-in 8 GB storage, the Avatar Mini HD VTX has the capability of recording HD video without interference from capacity and exporting video by USB cable. Besides, with Canvas Mode on Avatar Mini HD VTX, Betaflight full OSD display is supported and can be adjusted easily by remote control.

HDZero Nano Lite Camera is designed for feather-lite drones where every gram counts. At a weight as low as 1.5g, combined with the new Whoop Lite VTX at 4.5g with 0.4g dipole antenna enables a world’s-first production digital FPV solution of about 7g. The HDZero Whoop lite Bundle supports 1-3S power input with 25mW/200mW RF power and is capable of recording in 720P/60FPS with super low latency of less than 19ms. What's more, pilots can activate and configure its OSD function on Betaflight Configurator.

Injection Molded Canopy for HD Camera

Micro Canopy for HD Camera is specially designed to be compatible with Walksnail or HDZero HD digital VTX and has an adjustable camera lens of 0-45°. With the injection molding technique, the canopy is very durable and flexible for crash resistant. Besides, the hollow-out design not only reduces the influence of heat on electronic parts but also is available to be armed with decorative parts we prepared.

New 1102 18000KV Motors

1102 18000KV motors have a great balance between weight and power on 75mm 1S whoop drones. Only 2.9g with connectors. With the high 18000KV, it could have a great punch power even with only 1S battery. Also, it adopts a PCB connector to allow you to repair it easier once cables are disconnected.

Flight Controller

The latest F4 1S 5A flight controllers are applied to all BNF versions of Meteor75 HD. It features Serial ELRS 2.4G instead of SPI ELRS 2.4G for ELRS version compared to the previous version. The Frsky version reserves two UART ports for the available external receiver so it can be used as PNP. The ESC on the new board is powered by BB51 hardware in place of BB21. Last but not least, we update the gyro to BOSH BMI270 for better performance and stability since the new F4 1S 5A FC.

Two flight controllers will be sold separately. Stay tuned for new flight controllers coming up.

• F4 1S 5A FC (Serial ELRS 2.4G) V2.0
• F4 1S 5A FC (SPI Frsky) V3.0

Note: Pay attention, ONLY the newest Betaflight firmware 4.3.1 start to support this BMI270 gyrometer. Please check the below link to download the firmware and CLI dump file. If you update the 4.3.1 firmware from Betaflight official site, please flash the CLI dump file for Meteor75 HD.
