I am using a cheap $8 600vtl generic one on my 1st build (Not bad picture - no mounting bracket but comes with built in mic) from Banggood. It's the one featured on the basic build of the $99 quad by UAV Futures on YouTube. But I recently got 2 more ones I am gonna try out. The current one build I'm putting on a $18 Caddix Turbo Micro F1 with 1200VTL (supposedly has real low latency). The one I have for my next build is a Foxeer Monster V2, also 1200VTL (supposedly has excellent pic quality). Both of those come with brackets, but I wanna see which I like better. I think Runcams are most popular, but they are kinda pricey. (Don't think I would wanna risk one of those in a crash). I just stick to decent, reasonably priced ones.
