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?
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.
RSSI is the abreviation for Received Signal Strength Indicator - this sounds pretty self explanatory, but let’s look a little bit more into it. With wireless signal the RSSI metric is often used with wireless signal to get an idea about the strength of a received signal.
There is no standardized relationship of any particular physical parameter to the RSSI value, vendors usually define that for themselves. But what is standard is, that higher is better and 0 is the lowest possible (and thus, worst) value.
Thinking about building a 1S brushless whoop and you are not sure which AIO flight controller to use? I want to show you a couple FC’s which I think are viable choices and explain what I am looking for in my 1S flight controllers.
Obviously there is no ONE perfect flight controller, otherwise this article would be pretty short. It depends on what you are looking for, and this might be different for everyone. I will show you what I look for and how my decision process looks like.
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.
