The audio is a bit off but it took too long to render so I don't want to do it again.

This is a park with what they call the "Big Field" in it and the field is about 600 meters end to end, 35 acres. The entire park itself is like over 300 acres but a lot of it places I don't want to go. The road that spans around the field takes you out to the main road so I had to rip the grass up instead. As I got close to the other side of the field I said screw it cause I was heating that motor up and building a grass birds nest inside the truck. I had to cut about 5 minutes of exploring out at the end cause I accidentally deleted the audio for it. This park is real close to NSCU and sort of part of the campus. It will always be somewhat populated no matter the time of day or night because of the dog park. Because people are wack I'm not sure I could roam this place too much without someone complaining to the cops about riling their dogs up.

I was scared to full throttle it because it was liable to hit some Dukes of Hazzard jumps but I did end up ramming into a curb and almost flipping the truck later. I had no idea how level that field is or how jacked up certain spots could be but I just kind of 80% throttled it and it worked out. Being that it's largely open space I can easily span the entirety of it because I would only be putting one building in the way anywhere I went. Such a layout is real ideal for the O3 on the ground but about the furthest point I went is where the 1.3g audio started to get fuzzy. There are some 'cyclocross' or something paths nearby this field I'm going to check out but other than that I guess not much going on but a big ass field and canine dinosaurs.

I wasn't sure what those guys were doing in the field but I saw the one guy out there placing markers that looked like whatever they had that was white. I later could see they were playing disc golf or something like that. They were probably mad that I might run over or drag their markers but thanks to the O3 I could actually see them and steer around them. At the time I was sort of just reflex driving around what I thought might have been trash. Now imagine using what they were doing as an example of how such an FPV system could be useful for more than just exploring. Technically with 3 more available servo channels I could add a basic robot arm that could swivel left and right, up and down, and then actuate a grabber that could pick up a disc or trash in general. 4 channels could make an arm that booms out or rotates etc. So instead of walking out and grabbing a disc, dropping a marker, then throwing/walking it back.. you just drive the car out there and do it.
