Amperage meter scale ratio: 180

Dimensions: 43 x 44mm / Weight: 15.8g

Compatible with all major FPV receivers from vendors such as Fatshark, ImmersionRC, etc.

Supports the standard 40-channel set: band A, B, E, Fatshark, and Raceband.

SmartAudio input allows remote control by the flight controller. Change channel, transmit power, and more from Betaflight OSD, flight controller USB port, Taranis Lua Script, and more.

All parameters are controllable via push-button on the side of the unit, for cases where SmartAudio is not used.

MMCX connector is durable and easy to use. Rated for 100’s of mating cycles. Easy and quick antenna changes. No more ripped-off UFL connectors.

LED indicators for channel, band, and power. Allows easy check of vTX parameters simply by glancing at the quad.

Variable transmit power from 25 mW to 800 mW. Use 25 mW for a race and then easily switch to 800 mW for freestyle.

0.5 mW True Pit Mode allows you to power up safely without the risk of knocking other pilots out of the air.

Built in microphone, so you can listen to your motors while you fly, no matter how far away you fly.

Standard 36mm form factor allows you to mount the Atlatl directly on your flight controller stack.
