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 Crux 3 is a super light weight 3” toothpick based on Happymodels CrazybeeX all in one board. And light weight is not just a buzzword in this case - the model weighs in at just under 42g without a battery (just 70g with a 2S 450mAh GNB battery).
When I first saw the URUAV UZ85 on Banggood, I could not believe it - a 85mm copter for 78$? I have to try this one! When I received it, I was wondering about the package - why is it so small - did I get the wrong item?
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 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.
When I first saw the Geelang Wasp85 on Banggood I thought: “Ah something different” - I want to take a look at that. Bangood was kind enough to send me one to check it out.
I was hoping that it is a bit of a sleeper and surprises by just being plain awesome, unfortunately that was not completely the case.
The total weight is 46.5g without batteries and 63g including two 300mAh, 1S batteries. I like to fly it with GNB 2s, 450mAh batteries and with those it weighs in at 75.2g.
The EMAX Tinyhawk 2 Freestyle is the third micro quad released by EMAX that is built on basically the same stack as the Tinyhawk 2 and the Tinyhawk 2 Race both of which I have reviewed before.
Both are super solid quads that you can have a lot of fun with. One to fly at home and one aimed at micro racers. I have put a couple of hundred packs through each of them and have especially been enjoying the Tinyhawk 2 Race. Now lets have a look at the newest addition to the Tinyhawk 2 family.
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.
The Tinyhawk 2 Race is basically the outdoor version of the Tinyhawk 2. They share a fair amount of components. The Tinyhawk Race is a 2S, 2” toothpick style quadcopter which you should definitely fly outside.
You can also fly it on 1S, but honestly - once you tried the Race on 2S there is no going back.
