WALKSNAIL Ascent Lite+ (Plus) Kit
by WALKSNAIL

The Walksnail Ascent Lite+ (Plus) Kit (Model: WN13-7007B) is an ultra-lightweight 1080p 120fps digital HD FPV transmission system engineered by CaddxFPV for micro FPV drones, tinywhoops, fixed-wing aircraft, and RC vehicles. Featuring a compact 23.5 x 23.5 mm VTX board with a 20 x 20 mm M2 mounting pattern, the Ascent Lite+ VTX weighs only 2.75 grams (without metal cover) while outputting up to 500mW of RF power for reliable HD video transmission up to 8km.

Equipped with a 1/2.8-inch image sensor nano camera (12 x 14 x 15.8 mm) with a 147 degree wide-angle lens, the system captures smooth 1080p footage at 120fps with an average latency of 35ms. The unit includes an onboard microphone for real-time live motor and flight audio, automatic channel frequency hopping to mitigate interference, dynamic bandwidth selection (5M/10M/20M/Auto), and Canvas mode OSD support across major flight controller platforms including Betaflight, INAV, and ArduPilot.

Key Features

• High-Frame Rate 1080p/120fps Video: Delivers crisp 1080p HD video at up to 120fps with an average end-to-end latency of 35ms.

• Ultralight 2.75g VTX Core: Compact 23.5 x 23.5 mm VTX board weighs just 2.75g (without metal cover) with 20 x 20 mm M2 stack mounting holes.

• Up to 500mW Transmit Power: Outputs up to 500mW of RF power for extended HD transmission range up to 8km.

• Built-In Real-Time Microphone: Onboard microphone records live audio (motor, propeller, ambient noise) synced with HD video feeds.

• Nano-Sized HD Camera: Features a 1/2.8-inch sensor, 147 degree wide-angle FOV, 16:9 aspect ratio, and micro 12 x 14 x 15.8 mm dimensions.

• Smart Frequency Hopping: Automatically detects interference and switches channels in real time across the 5.730 to 5.815 GHz frequency band.

• Wide Flight Controller Compatibility: Full Canvas mode OSD integration with Betaflight, INAV, FETtec, KISS, and ArduPilot flight stacks.
