The TX2501 is a powerhouse video transmitter designed for long-range pilots and those flying in high-interference environments. Featuring a robust CNC aluminum heat-sink casing and an integrated active cooling fan, it maintains stable performance even at its maximum output of 3.5W. Whether you are chasing mountains or flying through thick concrete, the TX2501 ensures your video link remains rock-solid.

Key Features

• Massive Power Output: Switchable power levels (25mW / 800mW / 1600mW / 2500mW). Under optimal conditions, the maximum power can reach a staggering 3.0W ~ 3.5W.

• Full 6.2G Band Coverage: Supports 64 channels across 8 bands (A, B, E, F, R, L, X, S), providing a wide range of frequencies to avoid interference.

• Advanced Thermal Management: The combination of a precision CNC-machined aluminum shell and a high-speed active cooling fan prevents thermal throttling and ensures consistent power output during long flights.

• Smart Control: Supports IRC Tramp protocol for easy adjustment via your flight controller OSD, or manual adjustment via the onboard button and LED segment display.

• Standard Mounting: Features a standard 30.5x30.5mm (M3) mounting pattern, making it a perfect fit for most 5-inch and larger FPV frames.
