RushFPV Rush Max SOLO 5.8GHz 2.5W 37CH VTX with Smart Audio

The RushFPV Rush Max SOLO is a high-power 5.8GHz analog video transmitter engineered for extreme long-range FPV, mountain surfing, and heavy-lift cinematic rigs. Pushing up to a massive 2.5W (2500mW) of output power, this VTX is built to maintain clear video feeds through heavy interference and solid obstacles where standard transmitters fail.

Key features

• Extreme 2.5W maximum output for uncompromised long-range signal penetration.

• Full-cover CNC aluminium heat sink designed to manage high thermals and prevent power sag during flight.

• Built-in AGC microphone for real-time onboard audio monitoring.

• Smart Audio support for rapid channel, band, and power adjustments directly via OSD or radio.

• Wide 7-36V input voltage range allows direct power from 2S to 8S LiPo batteries.

Specifications

• Input voltage: 7-36V (2-8S LiPo)

• Output power: PIT / 25mW / 500mW / 1000mW / 2500mW

• Channels: 37CH

• Control protocol: Smart Audio

• Camera power output: 5V

Due to the extreme 2.5W power output, this VTX requires continuous active airflow over the CNC heat sink to remain cool. Avoid leaving the transmitter powered on a static test bench for extended periods to prevent thermal throttling or hardware damage.
