Product Information

The RC Electronics Sparrow is one component of RC Electronics model aircraft telemetry system. The Sparrow is the on-board unit intended to be used with the Finch or Snipe Ground station, or with Jeti back-channel link (other brands will be supported shortly)
The Sparrow is designed to measure many parameters of an R/C model aircraft and transmit them to the ground via the telemetry channel working on 433 MHz frequency (optional Sparrow RF module required) or using Jeti ExBus/P23Bus/HoTT. The unit is capable of measuring sink/climb rate (Vario), altitude, noise level, servo pulse on servo inputs, GPS data with 5Hz refresh rate and supply voltage. For data storage, it has an external 8Gb uSD card (included). All flights are stored to this external SD card in IGC format for later review and upload to online competitions sites (OLC, Soaringleague etc). Input voltage 4-10V
