Axisflying Smurfs Mini 5.8GHz 40CH Analog VTX, 25/50/100mW FPV Transmitter, IRC Tramp OSD, IPEX, 5-25V, 25.5×25.5mm, 3.1g, Button & Betaflight Control for Micro RC Drone Whoop Drone
Description
Small Size. No Performance Compromise. The Smurfs Mini weighs 3.1 grams and measures 30×30mm with standard 25.5×25.5mm mounting holes. It disappears into whoop builds. It's negligible on toothpicks. It fits micro stacks without dominating them. Yet inside that compact footprint lives a full 40-channel VTX with IRC Tramp protocol, dual control modes, and up to 100mW output. Three Power Levels. Balanced Range and Heat.
| Power Level | Use Case |
| 25mW | Indoor whoop racing, proximity flying |
| 50mW | Park flying, light outdoor use |
| 100mW | Maximum range for micro builds |
| Note | 100mW meets daily FPV flying needs—balancing range and heat control without pushing into power levels that require additional cooling or regulatory complexity. |
IRC Tramp. OSD Control Without the Price Premium. The Smurfs Mini supports IRC Tramp protocol for full Betaflight OSD control. Change channels, bands, and power levels from your radio—no disassembly, no button hunting, no landing between adjustments. The VTX table import file is included for quick Betaflight setup. Dual Control Modes. Button + OSD. **Button Control: Two physical buttons with LED feedback. Short press (1s) changes channel. Long press (3s) changes band. Power button cycles 25→50→100mW. Green LED = Channel. Blue LED = Band. Red LED = Power. **OSD Control: Full IRC Tramp integration via Betaflight VTX tab. Configure everything without touching the VTX. 5-25V Wide Input. Any Micro Build. Direct 5-25V input covers 2S through 6S LiPo power. IPEX antenna connector keeps the profile low. 4-color twisted silicone wire included for clean, flexible wiring. 4 vibration damping silicone columns isolate the VTX from frame vibrations. 40 Channels. 6 Groups (A/B/E/F/R/L). Full 5.8GHz coverage with standard bands plus L-Band for additional frequency flexibility. Find a clean channel in any environment. Key Features * 3.1G ULTRALIGHT: One of the lightest 100mW IRC Tramp VTX available. Fits whoops, toothpicks, and micro racing builds. * 40CH / 6 GROUPS (A/B/E/F/R/L): Full 5.8GHz coverage plus L-Band. Clean frequency in any environment. * 25/50/100MW: Three power levels. Balanced range and thermal management for micro builds. * IRC TRAMP PROTOCOL: Full Betaflight OSD control. VTX table import ready. Switch channels, bands, and power from your radio. * DUAL CONTROL (BUTTON + OSD): Physical buttons with LED feedback for standalone setup. OSD for remote configuration. * 5-25V WIDE INPUT: Direct 2S-6S LiPo power. No external BEC required. * IPEX CONNECTOR: Low-profile antenna interface. Copper tube antenna included. * 25.5×25.5MM M2 MOUNTING: Standard digital VTX footprint. Drops into most micro frames.

Important Usage Notes - Install antenna before powering on. Operating without an antenna will damage the VTX. - Ensure adequate airflow. Install with space around the module for heat dissipation. Overheating protection will reduce power or shut down the VTX if cooling is insufficient. - Verify voltage and polarity before connecting power. Incorrect input will damage the module. Input range: 5-25V DC (2S-6S).
