As is the case with most hobbies, much of my money was spent on initial startup costs: an RC transmitter and battery charger, while essential, would only need to be purchased once. If I want to build more rc-craft in the future, this will make it a lot easier.

**Frame:** Really nothing special here. I got a [Reptile 500](https://www.ebay.com/sch/i.html?_nkw=reptile500+v3+quadcopter+frame) frame... or something. Honestly not sure on the name here. Basically my strategy was to browse [hobbyking](https://hobbyking.com) til I found something I liked, then I headed over to ebay, to buy something similar. You can get frames for pretty cheap off there if you're willing to wait for it to ship from China. I wasn't, so I paid an extra $10 to get it from a US seller.

Overall I'm pretty happy with the frame. It's simple and it was cheap. At first I thought 500mm between motors would be huge, but I've grown to like it and how much space it gives me. I have plenty of room to jam all of my various gizmos throughout. Being cheap and from ebay, it was a bit of an effort to secure all the arms to the frame; aligning the holes was more difficult than anticipated. But once mounted they're pretty solid, and have already survived a few crashes with ease.

I was stupid and tried to screw the motor in through all 4 holes on the arm with some aggressive dremeling, before realizing there were two holes for my motor size, and two for a different size.

This plate+anti-shock mount combo was intended to go in the front of the drone for fpv. While that is something I would like to eventually add, this plate also happened to be the perfect size for the Flip32. So I drilled a few holes, allowing me to mount the naze as close to the center of gravity as was reasonable:

This is the handiest edition I think I've made. This allows me to plug in the battery with the confidence that the motors aren't going to immediately attack me. Currently I only use one side of the switch, but in the future I plan on having one side turn everything on, while the other side only turns on the small electronics(and not the finger-slicing motors):

## Part 2: Fixes and Tweaks
|
||||
Its been a few weeks since writing part 1 and a lot has changed. For starters the thing actually flies now. As I mentioned in part 1 I had some troubles getting my first set of esc's to work correctly. So I replaced them with new, smaller ones, and *still* had trouble with them. That is until I finally sat down and figured out how to calibrate them (protip: read the instructions that come with your products!). With that squared away, this hunk of junk finally became a flyable drone as opposed to a 180deg flipping machine, as shown in the video below.

Unfortunately I dont have any footage of the first successful flights(I was out by myself, as usual), but just know it was legendary. Flight 1 went well until I accidentally crashed into a pine tree, which provided a surprisingly cushy landing. Flight 2 was absolutely beautiful until I somehow managed to clothesline my drone on literally the only power line in the immediate vicinity. The rest of the initial flights followed a similar pattern. All-in-all, I ended up buying another 4 sets (with 2/set) of props, after breaking 4 of them. Seeing as this was my first real drone-flying experience, and I was still tweaking some of the settings, I chalk it up to the cost of learning.
