Frequently Asked Questions

Choose the receiver protocol matching your radio transmitter:

  • ELRS (ExpressLRS 2.4GHz / 915MHz): Modern open-source protocol with ultra-low latency and extreme range.
  • TBS Nano RX (Crossfire): Battle-tested long-range protocol with proven reliability.
  • PNP (Plug and Play): No receiver installed — install your own receiver module.

For 7-inch long-range quads like the GEPRC MOZ7 V2, we recommend a 6S 3000mAh – 5000mAh LiPo for dynamic freestyle flights, or a 6S2P 8000mAh Li-Ion pack (21700 cells) for maximum cruising flight times of 25–30 minutes.
