Since this is my first quad I've nothing else to compare against but I LOVE putting the DJI FPV goggles on and flying the SlamNasty ... I feel like Top Gun!! LOL

Unfortunately I almost lost the SlamNasty yesterday. I was at my parents house, flew up, and was rotating around to capture the surrounding neighborhood, etc. After a few circles, I went to fly back down only to realize the wind had blown me away from their yard and I'd no idea where I was!! At this time the video started to get choppy and showed 5Mbps. I panicked and started bringing it down before I lost complete control. Eventually the video froze and I slowly let the throttle down to try and land softly. My brother pointed me in the direction he'd seen the quad flying off to and we so we headed in that direction with the Tx to see if the receiver would relink. We walked almost 1/4 mile and I thought I'd lost it for sure and when it eventually relinked and showed 50 on my crossfire connection. I kept heading down the road until it finally reached 100 and shortly after I could hear my Vifly buzzer when I was triggering it with the Tx. As we approached a house we seen several people in the back yard bent over and I was thinking this is definitely not good. I began down their driveway and as I triggered the buzzer I heard it loud in clear in the front bushes of this house so I grabbed it and got the heck out of there!! Thankfully they were just back there doing some sodding and nobody was hurt, no property damaged, and only a broken prop tip and bent props!!

I'd originally wanted to put a GPS module on this build but figured maybe I didn't need it or couldn't because I don't have a FC with barometer; however, after this instance, I'm getting one and not having this happen again. If I had the GPS I could've used the compass to quickly know which direction I was and flown back without issue or worst case activated RTH manually or through failsafe. I'm told as long as I have ~8 satellites linked I'll be fine without the barometer ... do you think this is true or should I be adding a barometer chip? Which GPS are you going to use?

Oh man...you got lucky! Yeah, the GPS is a must considering you'll slowly want to fly further and further away with the digital stuff and comes in really handy. I use the Beitian BN-180, you can find it on Amazon. I don't think you'll need a barometer for altitude. Since the GPS locks onto multiple satallites to get a 3D lock it'll determine your altitude via GPS. One thing to know though - sometimes it takes a while for your quad to lock onto 8 satallites (default min satallite #) before being able to arm your quad...just wait a couple mins.

While I believe this FC has battery pads on the bottom, I don't think I can fit the wires underneath, at least not easily on this build, so I'll take your advice and secure the pigtail to the frame in order to prevent ever having this issue, thanks for the generous tip!!

I've soldered many things from my guitar pots/switches to doing the RGH mod to my Xbox many years ago in which I had to solder wires to pads the size of sewing needle tips!! I lifted the pads/traces on something I was soldering long ago which taught me the importance of always using flux paste. It makes a HUGE difference in the ability to make solder melt, flow, and adhere to the most difficult items quickly. I never solder without it anymore and haven't lifted a pad since. If you don't know, you don't need more than a little dab, and you want to exhale while soldering otherwise the smoke will give you a headache and has sticky resins in it which will stick to the inside of your lungs. Once I'm done soldering, I use a Qtip with rubbing alcohol to wipe the solder joints down in order to remove the sticky Brown residue that's left over.

As far as cable management, my dad has OCD and is a perfectionist. Growing up we had to keep the house in perfect order as he'd spot a crumb on the floor like a hawk spots a field mouse from a far distance. In fact, his house is so clean you can literally eat off his garage floor, and while I'm not that bad, it's rubbed off on me as everything I organize from books, to decorations have to be equidistant, symmetrical, right angles, etc. etc., and so goes with any projects I work on. While it's certainly not perfect, I appreciate the compliment! :)
