When I first saw the Baby Nazgul, I knew I had to try it. I am a big fan of the iFlight Alpha A65 and I have heard people raving so much about the 5” Nazgul, that the Baby Nazgul just has to be awesome - right,… right?
Let’s first address the elephant in the room - quite literally: This micro copter weighs in at 29.1g with CRSF receiver, if you add a 300mAh GNB battery the weight adds up to 37g. Without the CRSF receiver it weighs in at 26.9g - still 3.1g more than its whoop counter-part the iFlight Alpha A65 which weighs in at 23.8g without a battery.
Happymodel was the first manufacturer to seize the opportunity for a quick buck and produce ELRS hardware. ELRS is an open source control link and I am pretty sure you have heard about it by now. I am a big fan of ELRS - been watching them basically since the beginning.
I am super stoked seeing more and more manufacturers implementing this Open Source hardware and I am confident that sooner or later it will replace FrSky D8 compatible SPI receivers on AIO boards.
In this article I would like to feature a project that I have recently learned about - the YOLO flight controller. Actually it is not a single flight controller, rather a family of designs that share the same base. The aim is to provide something for everyone: from 1S to 6S!
Finding this now, after writing my article about my “perfect” flight controller is a big coincidence, really fits perfectly and makes me totally pumped about this flight-controller.
After Happymodel, BetaFPV is the second company jumping on the hype train and releasing ELRS hardware. I am pretty stoked seeing more companies releasing hardware based on an open source project, so I am excited to showcase some of the new hardware.
I am a huge fan of ELRS - an open source control link for radio controlled models. I have followed the project since pretty early on and even built a DIY transmitter module and receivers. I never had it in production use since it was simply to cumbersome for me to DIY the receivers and I was hoping that some day, some manufacturer will pick this system up commercially - which is happening now.
In this post I will try to explain why I personally no longer recommend buying FrSky products. This can also be seen as an open letter to FrSky - although I highly doubt that they will be interested. Some of my issues I tried to discuss directly with them, but they did not really seem to care too much about any of my input.
I have been thinking about writing this article for some time - and even let it sit for a couple of months - but neither my views nor the situation at hand did change, so I decided to finally publish it and if it is just for the sake of linking people here when they ask why I no longer recommend FrSky products.
It took me some time to join the HD FPV community. I have been following the progress since the first DJI HD system has been released in late 2019. At this point I was interested in the tech, but generally the product was not for me: the air-unit was simply too big for my micro needs.
Then the Caddx Vista came around. I was hesitant - will Caddx be the only company licensed by DJI? Will they have better QC in place than with their regular products? What is Fatshark going to do - is their HD system going to be better?
The Eachine US65 Pro has some sentimental value for me, since the first article I wrote on this blog over three years ago was about the Eachine US65. A lot has happened since then and I was super excited when Banggood offered to send me one for review - unfortunately at this point I am already a bit late to the party since this copter has been released in late 2020. If it is still a good choice in 2021 you will find out here.
The Eachine US65, is a 65mm, 2S whoop set - it comes with the copter, batteries, charger, props and a nice carrying case.
Caddx’ Ant line of FPV cameras are very popular, especially with analog RTF micro quadcopters. Almost all analog micro copters released lately come equipped with one of those.
This comes down mainly to weight and price - but the feature set is actually also pretty decent.
Let’s take a closer look at which models of the Ant there are exactly, what they have in common and what sets them apart.
When I first saw the Rekon 3 Nano Long Range, I thought - awesome, a 1S 18650 RTF (Ready To Fly) micro quadcopter - I need to check that out! Banggood was kind enough to send me one over for review.
Designed by Dave_C and manufactured by RekonFPV the Rekon 3 Nano Long Range will have a very specific target audience, and in this post I want to take a closer look and help you decide if this might be something for you.
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.
