Reddit mentions of Capri Tools 20013 Professional Wire Stripper and Cutter

I'm in the process of building my first FPV drone with my 11 year old son. Tools I owned or have purchased for this are:

A set of small screw drivers. I found a set in the bargain bin at NAPA Auto that had straight, philips, a few hex, a few sockets.

A decent electronics soldering station. Not the gun. I have a digital Weller that is easy to control, but the analog is just as good for these purposes.

A third hand. There are many different kinds. I got a cheap $5 one at Harbor Freight. Not great, but does the job.

Solder, de-soldering wick, flux (maybe)

Depending on where you're doing your work, might want an air-filter or fan.

A magnifying lamp is helpful but not necessary.

An assortment of board stand-offs/spacers is handy.

A good small pair of wire snips.

Wire stripper

A digital multimeter is not a bad idea.

Those are all the major tools you might need. Plus all the drone parts. batteries/charger. Radio/receiver. Camera/receiver(goggles or screen).

In short, it's a lot of stuff. The drone parts end up being the least expensive part, honestly.

Above links are just examples, not necessarily endorsements.

You mentioned you're on a budget, which I totally understand. Building is not the cheapest route, but it's been a lot of fun so far. People who've done it for a while tend to forget the cost of tools. Once you've built one, subsequent drones are relatively cheap. You can re-use batteries, the charger, most decent radios, even the receiver.

If you're not in a hurry, Bangood is a good source for cheap(er) parts. You're on your own for support, usually, but there's lots of help out there.

> Splice them into your trailer wiring

That's what I did. I went up about 4" from the 7-pin plug, cut the necessary wires, used uninsulated butt connectors with a closed-barrel crimper and adhesive-lined heat shrink to splice in a 6-pin Deutsch DT connector pigtail, then built my own wiring harness that plugs into the Deutsch connector and ran it up to the headache rack.

Went with the 6-pin Deutsch connector since I only needed 5 of the 7 wires (LT, RT, Tail, Backup, and Ground) and 5-pin Deutsch connectors aren't available. Deutsch DT connectors are frequently used in the automotive aftermarket (probably more so than Delphi Weatherpack connectors). I know Rigid Industries uses them for their LED lights, and Smith Race Wire uses them for parts of their custom wiring harnesses.

Also, since you can only close-barrel crimp one end of the uninsulated butt connectors, I chose to close-barrel crimp the side that had only one wire (since closed-barrel crimping is more secure, and the one wire was looser in the connector) and used Channel Lock 909 Pliers to crimp the end with two wires.

Once you made your harness, make sure you slip it into some split wiring loom. Using a loom insertion tool makes quick work of that. Wrap the wiring loom with non-adhesive dry vinyl tape for a factory-finished look and to avoid a gooey, sticky mess in case you need to unwrap the wiring harness in the future.

Finally, a good wire stripper will save your hands a lot of fatigue compared to using a standard wire stripper that you have to always pull the wire through.

How do I know what gauge to get? I this sufficient Wire, Bananas and Wire Cutters. I think I will skip the DAC for now and see how everything sounds? As I can always buy one later and add it in but how do I know if I need one?
Edit: Thank you for the help!
