The Spektrum AR20400T is a 20-channel, full-range 2.4GHz PowerSafe telemetry receiver designed for high-current aircraft such as giant-scale and turbine jets. Its patented PowerSafe redundancy system uses dual 13 AWG battery leads with true dual-battery isolation — if one battery fails, the other seamlessly takes over. An innovative battery capacity monitor tracks cumulative consumption across flights and can auto-reset on charge. A built-in "Black Box" logs flight data, battery status, and telemetry to a micro SD card. The integrated barometer provides altitude and vario data without additional sensors, and Forward Programming lets you configure the receiver wirelessly from any compatible Spektrum transmitter. If your transmitter supports 11ms frame rates, the AR20400T delivers lightning-fast input-to-output response ideal for aggressive 3D, IMAC, and turbine flying.
