DJI action 5 vs. my bungee cord phone setup +DJI settings

Got an action 5 on sale for $380 CAD, and a stuntman chesty. I can't believe how good it looks. I upgraded from an LG V20 strapped to my chest via strings and bungee cords. Most of you said it looked terrible, even in 4k30, without stabilization. I thought it looked okay when city biking. The difference is huge. I guess I'll get a boost lens now. The cam is really easy to use, the chesty is super comfy and if you mount the stuntman hook upside down, this is fully pressed against it meaning I didn't have to angle the DJI at all. I'll experiment with that tomorrow cuz the view looks a little low, I tried to put the chesty high up but mounted the chesty attachment upside down. I think it looks pretty good, it seems like I just needed to up the shutter speed to stop some motion blur. I'm building a PC so I'll be able to do D-log later with woods footage. I guess I'll take it to the woods tomorrow to show the same downhill section. I'm realizing now I'll need more batteries and an SD card.
