  • The SPRacingTBEC is the only Race Transponder to feature a built-in 5V regulator!
  • The built-in 5V 1 AMP regulator means you don't need a separate 5V regulator. Plenty of power for your FC, RX, LEDs, etc.
  • Range - Works at distances up to 5m, even outdoors in sunlight. Use more track-side receivers to further increase sensitivity.
  • Dual IR LEDs - Two LEDs allows you to position for greater intensity or for clockwise and anti-clockwise tracks.
  • iLAP Compatible - Works with the most popular transponder receiver system currently in-use worldwide today.
  • Highspeed - Uses a high-speed transmission to eliminate interference.
  • 7-Digit code - Longer codes, compared to other systems, means you won't have issues with duplicate codes.
  • Flexible Form Factor - Mount using 30.5mm mount holes and stack above your FC. Or remove the tabs, heat-shrink it and use velcro to mount as appropriate.
  • Flexible Power Options - Power using 2S-5S Lipo OR power from existing 5V supply, you choose.
  • Suitable for racing clubs or pilot ownership
