    If you are the first type then you might want to look at ExpressLRS. A cutting edge open source control link based on existing 900Mhz and 1.4Ghz hardware.

  • What receiver should i get? | 2021-04-29
    ELRS has gone up to 40km on 900MHz and 33km on 2.4GHz. It takes much less power too.

  • Alternative RF Filter
    Yeah, I noticed that text. Discreet component filter isn't really an option, I don't think. The project is a 2.4Ghz receiver,
  • Crossfire or tracer?
    I think it sends... RSSI and VBat back right now, maybe? Nothing like a full telemetry solution. has been open forever and adds full telemetry.
  • Thru hole soldering makes a build so clean (full build in comments)
    ELRS recently (well, since a couple months ago) added .frk boot loaders for reversibly flashing ELRS. Those you can flash using the passthrough. I assume you can then flash the rest of ELRS using the .frk bootloader, also using the passthrough. Probably with this tool I think I'm going to buy a couple of those $10 Jumper R900 Minis and try ELRS :)
  • New to the hobby, made a bad purchase, need help.
    You can also flash ExpressLRS to the MX, reversibly, from OpenTX menu using an S.Port cable
