Walksnail Ascent HD Lite+ Digital FPV VTX Kit

Because carrying extra grams on a micro quad is a sin against thrust-to-weight ratios, Walksnail squeezed a full 1080p 120fps digital FPV video transmitter into a ludicrous 2.75g board. The Walksnail Ascent HD Lite+ Kit brings 500mW RF output, sub-35ms latency, and onboard live audio directly to your ultra-light micro FPV builds. After ten years of supplying UK pilots with cutting-edge FPV gear, Unmanned Tech knows when a VTX breaks boundaries—this board renders analog micro setups obsolete.

Highlights

• Powerful. Secure. Smart  
• Built-In Audio Transmission

Why You Want It

If you are tired of squinting through grainy analog static just to keep your 1S and 2S builds lightweight, the Ascent Lite+ is your answer. Walksnail shaved off every microgram without sacrificing your video link stability, delivering extended range, smart frequency hopping, and crystal-clear 1080p digital audio-visual feedback. Stop sacrificing flight time for video quality—fly both.

What receiver does Ascent Lite+ work with? Can I use it with my existing FPV goggles?
Ascent Lite+ works directly with Ascent goggles. For other FPV goggles, simply pair it with the Ascent VRX or Ascent VRX Pro receiver, which provides HDMI output to connect any HDMI-equipped goggles, monitors, or TVs.

Does Ascent Lite+ support audio recording?
Ascent Lite+ features a built-in microphone but has no onboard storage. When paired with Ascent Goggles or the Ascent FPV VRX Pro, synchronized audio and video can be recorded to the receiving device's microSD card at 720p/60fps, 720p/100fps, 720p/120fps, or 1080p/60fps.

Is the 8km range achievable in real-world conditions?
The 8km figure is the maximum one-way range tested on a fixed-wing platform under ideal conditions. Real-world range depends on environment, interference, antenna setup, and battery level. The built-in auto frequency-hopping helps maintain a stable link in challenging conditions.

Is the Ascent Lite+ compatible with the Avatar system?
No. The Ascent Lite+ is part of the Ascent digital system and is not compatible with the Walksnail Avatar system.

How much latency should I expect during flight?
End-to-end latency can be as low as 35ms, measured in open, interference-free environments. Actual latency may vary depending on RF conditions and system configuration.

Can I record flight footage directly on the Lite+?
No. The Ascent Lite+ does not include built-in storage. Please record via your Ascent goggles if you wish to save footage.
