C Rating? Mili Amp Hours? How many cells?
When it comes to the LiPo batteries we use in our hobby, there are a couple of specs you simply need to know about, what they mean, how to interpret them and most importantly how to compare them.
At first all those specs seem a little bit overwhelming, but when you look at them one at a time, they all make sense and are not all too complicated.
And this is what this post is all about, I will look at all the different specs and explain what they mean and how they interact with each other. I will also give you some general LiPo related tips.
The HappyModel Cine 8 is - as the name suggests - a 85mm cine whoop with which you can carry a Insta360 Go. This copter - similar to the UZ85 - comes as a kit which you have to assemble yourself - and there is no soldering required.
I really like the concept of having to put it together yourself. Everything is plug and play, meaning that all the wires come with plugs and you just plug them in and you are set. The assembly can easily be done in under an hour.
I was intrigued when I first saw Nvision Junior Racer75 - I am a sucker for the color purple, so this one instantly won my heart. I have never heard of Nvision before, but the copter seemed super sturdy and I needed to try it out.
This is a whoop sized, 75mm quadcopter - but this one is intended to be flown with 2-3S - and I really recommend 3S for this one, but more on this later. Let’s first address the elephant in the room - this thing weighs in at a whopping 55g without a battery. This is pretty substantial - especially since there are whoops in this size class that weigh less than half of that.
The FullspeedRC TinyPusher is, as the name suggests a pusher whoop, meaning that the motors are mounted upside down and are pushing the air down. This is done in order to have more space on top of the whoop to mound an HD camera platform of your choice, making it a cinewhoop.
Instead of going for an all in one cam, which is responsible for FPV feed and HD recording, this model is intended to be used with a dedicated HD camera. There are mounts available, one for a naked GoPro and for the Insta360 Go.
The Geelang Anger 85X 4k caught my eye, not only for the 4K recording. Also I liked the previous Geelang product I reviewed - the Geelang Wasp 85X quite a lot - currently my favorite toothpick sized quadcopter - so I had very high hopes for this one.
As the name suggests, this is a 85mm sized whoop, very similar to the iFlight Alpha A85, with one major difference - it can record in up to 4K to the onboard DVR.
A lot of brushless whoops came out lately, but which one is the best? In my opinion there is no one single best brushless whoop - it depends on what you want to do, this is why I decided to go with different categories.
Are you just starting out, do you want to fly indoors or do you prefer to fly outdoors, do you want HD footage or is DVR enough for you?
In this article I want to talk a little bit about battery connectors. Battery connectors - you wonder? Yes! What might at first sound like a boring topic with not much to say, turns out to be a quite interesting one, especially when it comes to brushless whoops.
Every mechanical connection is a place where electrical energy can be “lost” - or to be physically correct - translated into heat. You want your plugs to be as lossless as possible, so that all the energy can reach the place where it should be used - mainly the motors.
The iFlight Alpha A85 is the big brother of the A65. As the name suggests, this one is 85mm from motor post to motor post. And is capable of recording HD footage to the onboard DVR.
The quadcopter is advertised as “Indoor” - I don’t really think that this is true for any 85mm quad, except if you really have a big indoor space. At least for my apartment, 85 mm is way too big. I mean, I can fly it - but it is simply no fun. In a bando on the other hand, this is obviously a different situation - any place that you can explore, you will have a lot of fun with this one.
The GEPRC Stable 12A stack is intended as an all in one solution for toothpicks and microquadcopters.
Being an AIO, it is flight controller and ESC in one board. But this is not all - it would not be a stack without the video transmitter. The flight controller does not come with an onboard SPI receiver, so you have to provide your own receiver of choice.
I have been asking BetaFPV for quite some time for an AIO with blackbox - obviously I was not the only one.
This toothpick sized flight-controller comes with 20A ESC’s and 8MB flash for blackbox logging. But the blackbox is not its only selling point. Apart from that it also comes with three full UARTS. Since it is tootphick sized, it will unfortunately not fit into most whoop frames.
