Smaller frame. Same iron will.

The RXC28 rides into town as MXO's most compact micro surface receiver yet — trimmed down from the RXC52 series without giving up an inch of reliability. Built for 1/28–1/24 scale rigs where every gram and every millimeter counts, the RXC28 tucks into your tightest chassis without asking you to sacrifice signal.

• Featherweight build — just 1.8g, barely a whisper in the cockpit
• Pint-sized footprint — 18 x 11 x 6.6mm, smaller than the RXC52 series
• 3-channel micro surface receiver
• Built-in transponder — every variant comes with an integrated transponder standard, no add-on needed. Programmable with the MXO USB PG-ISP Programmer (sold separately) to set your own ID
• Available in 5 protocol-specific variants — pick the one that matches your radio:
  • Futaba-F4G
  • Futaba-S-FHSS
  • Sanwa FH4
  • Sanwa FH5
  • Flysky AFHDS-3A

Match your radio, drop it in, and ride — signal and timing, built-in from the jump.
