Since the late September, the pit mode outputs on both Atlatl HV and Kopis 1 have been changed into 0.5mw.

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.

Telemetry input allows remote control by the flight controller (where supported). Change channel, transmit power, and more from Betaflight OSD, flight controller USB port, Taranis, and more.

Variable transmit power from 25 mW to 600 mW. Use 25 mW for a race and then easily switch to 600 mW for freestyle.

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

Mono audio input allows you to install a 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 in your flight controller stack.

How to change the power and Channel?
If you are using it with a Betaflight Flight Controller built-in Betaflight OSD, you can manage the Atlatl's transmit power and Channel from within OSD.
More details about operation steps, pls read the manual.

Channel-Change Button:
The Atlatl is intended to be configured via Telemetry. If you can not use Telemetry, you can change Channels by using the Button built-on the surface of VTX.
The button is intended only as a fallback option for when Telemetry is not available. It would be very tedious to use the button as the primary means of configuring the Atlatl.

1. Hold the button down for 2 Seconds to switch from Telemetry Mode to Button Mode.
2.Then Press the button one time to change to the next channel. There is no separate " Band" and " Channel" function. The Atlatl will simply step through all 40 Channels that it supports.

Pit Mode: (0.5mW)
1. You can use the Betaflight OSD. In the VTX control section of the OSD ( Look at manual). There is an option, " Pit", which can be on or off. Manually change this option to put it into and take it out of, pit mode.
2. Or you also can hold down the Atlatl's button while you plug in the battery. This will make Atlatl to power up in Pit Mode. Just be remember to take it out of pit mode before flying, if not, you will lose sign.
