Question 15

Q: What should I check before buying the Jumper Smart?

Accepted Answer

A: First confirm that ELRS 2.4GHz fits your receivers, then decide whether a compact radio is really what you want, and finally check whether JumperTX, a single 18650 battery, and no module bay match your expectations.
