<p>According to <a href="https://oscarliang.com/frsky-xm-plus-rx/" rel="nofollow noreferrer">Oscar Liang</a>, the XM+:</p>

<ul>
<li>Is larger and heavier than XM (<em>21.5 x 12 x 3.5 mm – 1.6 g</em>)</li>
<li>Has diversity antennae, unlike XM</li>

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

<p>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)</p>
