Gps speedometer

[skunknuggit]

I see people in yt videos have these little stick on gps speedometer. I see a couple that look good on Amazon. Before I buy one does anyone have any recommendations? I don't want to buy a full on telemetry system i want to get a little cheap stick on one or something like that. TIA

SkyRC GPS GNSS works good. I have one. The new version has the better battery. Mine is the older, battery isn't the best. The app works good
