I have seen both XM and XM+ receivers and am wondering which one would be better to get for a micro-drone build. What are the differences in specs? (range, reliability, weight, etc)

According to Oscar Liang, the XM+:

  • Is larger and heavier than XM (21.5 x 12 x 3.5 mm – 1.6 g)
  • Has diversity antennae, unlike XM
  • Has solder pads in addition to pin headers
  • Doesn't support Smart Port telemetry
  • Has RSSI channel support on a dedicated pad and 16th channel
  • Has a wider input voltage range than XM (3.7v-10v)
  • $\begingroup$ The XM+ is actually larger and heavier then the XM: XM – 15.0×10.0x3.5mm – 1.0g XM+ (plus) – 21.5x12x3.5mm – 1.6g $\endgroup$

As far as I know, they are almost the same.

The only difference is that the XM+ has a diversity receiver so will be more reliable. It also weighs slightly more and is slightly larger (though it’s a negligible amount in my opinion).

If it were me, I’d go for the XM+ for the extra peace of mind.
