Quadcopter parts by Best-World

Today I'm going to try something new and review multiple parts from a single company that can be used together to make an almost complete quadcopter. Just add your own flight controller, receiver, and battery. Let me know what you think.

All of these products are sold on Amazon by Best-World. Just click on the titles to be taken right to the product page.

My video includes several parts but you can see the assembly of throughout it. This frame is in my opinion the perfect one to use as your first 450 size quad. It combines all the elements of cost, build, and function. When starting out you just want something basic that won't eat a hole in your pocket when you crash it; and yes I mean "when". This is right at that price point. Even further because this is the most copied frame you can find replacement arms anywhere. When I've broken them before it was about 8 bucks for a replacement.

Build- The arms of this quad are quite strong with no perceptible flex. Mounting holes are quite deep so you won't be using the small screws that come with your motor. No fear: longer ones are included here. The plates are where I'm a little disappointed. they are just strong enough that they wont be breaking in flight but you can bend them in your hand. Once assembles it isn't a problem but at least 3mm of material would be nice. They are pretty long so that does allow for plenty of space to mount everything flight related inside and still have room on top.

Function- The best design feature of these frames is that they allow for the front arms to be spread out and provide a less obstructed view when flying a camera. They also have a dedicated spot for your battery that protects it from above and below. Another element that I would like to see is the bottom plate also functioning as a power distribution board. In this case you have to either provide your own or go with a spiderweb of cables.

Even with this frames shortcomings, I'd still recommend it to someone wanting to build their first quad. There are some features missing more advanced users may want but that would mean you're spending more. Give this one a shot. I received this product free in exchange for nothing more than my honest opinion.

My video includes several parts but you can see the motors at the beginning and attached and running at the end. Best-world's motor selection includes a few different KV ratings. In this case I tried the 1400KV set of 4. First, having the matched set is just always convenient. You never know if a set of motors will be from a similar batch and having them packaged together give better odds of similar performance. The motors operated as expected. Each spun freely when not powered and consistently when they did have it. I took one apart and found it to have two good bearings, two set screws on top for adjustment and a c-clip on the bottom. The winding weren't perfect but so far they haven't shown issues. Every time I raised the throttle they spun up great so I have no complaints. These would be perfect for a budget setup so I'd recommend them. I received this product free in exchange for nothing more than my honest opinion.

My video includes several parts but you can see the ESCs at 1:11 and being attached throughout it. There's not much to say about them. Do they make your motors spin, Good news: Yes! I bought these as a set and each one power the matched motors similarly such that I couldn't detect any difference in pitch as thins spun up. No hesitation either. One great benefit of these is the lack of low voltage cutoff. This does mean that you need to monitor your batteries some other way. The advantage though is that when your in the middle of squeezing just one more minute out, your LV cutoff won't kick in when your way up in the sky. If it does you get a paperweight falling out of the sky and no-one likes that. Features like this are up to personal preference but I'd rather not have something that can cause a crash. If you're looking to so a basic cheap build I'd say to give them a try. I received this product free in exchange for nothing more than my honest opinion.

My video includes several parts but you can see the station at 6:06 where I solder wires to an XT-60 connector. This tool is the sort of thing you don't know you need until you're dropping parts and/or burning yourself. It's simple but having slots that are designed specifically for your connector means that they won't be moving at all. This product holds a bunch of different plugs so you'll get a lot of use out of it if you do varied work.

For example: I solder a lot of XT-60s and you need to have one hand for the solder and one for the iron. That means you need to find a way to steady the small part, but if you've ever put them int he jaws of a Helping Hand you know that they aren't steady at all. Any pressure pops them out or makes them move so you end up melting something or burning yourself. 

Build- The main body is solid aluminum. I like that you won't able to melt it and it has enough heft that it doesn't slide around when using it. The two thumb screws on either side are big enough to easily loosen. I found it best to adjust them just big enough that a plug could slide it snugly and then pull them in and out without having to open it all the time.

I really think it should be a little cheaper but if you're going to be soldering a lot of connectors and you have room in the budget go for it. I received this product free in exchange for nothing more than my honest opinion.
