No idea how accurate it is, but surely results are plausible. Bluetooth with iENV Android application also works, but instructions how to set it up were not clear. The secret is that you do not have to bind UT363BT with a phone. Just open the iENV app, enable Bluetooth in UT363BT and connect. No pairing required!
When little more than 3 months ago I announced iRangeX iRX-IR8M multiprotocol radio transmitter I did not expected it will take that much time to get the radio from Banggood. First it was delayed, than it was delayed and then sent via slowest post you can imagine.
Either way, it is finally here and this is my review of it (vol. 1 now, vol. 2 will follow).
Cloners gonna clone and chinesium keeps being chinesium! It did not take long for Banggood / Realacc to clone Lumenier AXII FPV antennas and call them Realacc UXII circular polarized FPV antenna. Coincidence? I do not think so.
I've ordered few of those in December, they arrived last week and this is what came in package
Unfortunately, in this case, the build quality was typical chinesium. As soon as I opened one of them, antenna disintegrated… oh bugger…
I only hope the other (the one I did not open) works like expected. I did not test them in real life conditions since the weather is rather bad over here. This weekend maybe… In a meantime, here is a video of what is happening inside Realacc UXII 5.8GHz antenna.
Is it only me, or is Matek starting to build very good FPV hardware? I think everybody knows Matek's PDB. Matek F405 flight controller series is also very popular. But do you know Matek also started to build VTXes? I didn't and when a friend showed me this:
I almost knew I want one. Matek 5.8GHz 40CH VTX-HV is quite interesting design. It can be mounted above flight controller: M3 mounting holes are 30.5 apart. That's not all, it supports serial protocol (Tramp), can be powered from 5V rail or main LiPo (7-24V), has u.fl IPX connector, comes with small dipole antenna and SMA pigtail, has 3 power levels (25mW, 200mW and 500mW) and supports Raceband.
But the best feature are: 2 buttons and a set of LEDs. It really makes setup super easy. Press Button A to select function, press Button B to cycle options (power, band, channel). And current state is presented with LEDs. Cool. Not like with TBS Unify Pro where you have to count blinks!
Bangood stated it uses SmartAudio, but it is not true. It is ImmersionRC Tramp protocol. Thank you Andrey for pointing that out.
Since I just started to add support for "old" FrSky XSRF3O flight controller to INAV (expect this in a release after 1.8) it might be a good idea to share few words about it.
First of all, it comes in a box. Why am I mentioning this? Because none of my flight controllers, and I own at least more than a dozen, came in box. C'mon, this is huge! I'm not joking, this is really a nice touch.
How is it until Christmas? 2 months and something. Pretty close. And like every year there will be problem: what to buy someone who has everything? Tough one, right? Sweater? Socks? Toy Stirling engine? I vote for Stirling engine for sure. There is only one precondition: recipient has to like mechanics 🙂
I’ve tested the cheapest toy Stirling engine from china you can get. For less that $20 you get a functional engine model that, surprise, surprise, works. Amazing, right? Here is my video review of it:
Oh, by the way, for me, this is the best toy ever!
Yes, I know it’s few months too late. And it’s not really a review but rather, since I was never able to use it or I describe my friends experience with RunCam Split.
I own RunCam Split. I own it for like 2 months now, and it’s still in a box. Never connected, never really used. And in the meantime, I’ve build 2 mini quads are rebuild third. Why is that? Is there something wrong with RunCam Split that I’m not using it anywhere? And not planning to? Let’s be quick about it:
I have a nasty habit of buying things and then forgetting about them. Something like that happened to Tiny Frsky 8CH Receiver (Wolfbox F802 software compatible) from Banggood I’ve purchased last year. For some time I used it in JJPro P175 quadcopter, but then it landed in a box and I forgot about until last week.
So, let’s do overdue “hands on” on Tiny Frsky 8CH Receiver from Banggood… Continue reading Hands on: Tiny Frsky 8CH Receiver from Banggood
So many things to do, so little time… I’ve purchased DemonRC NOX5 quadcopter frame more than a month ago, but had some time to take a look at it only today. This is not a cheap stuff. More than a $100 for a 5″ frame is few times more than I’ve used to pay. But I just had enough of cheap chinese frames. Don’t get me wrong, they usually fly alright, but both quality and user friendliness lacks a lot. With “premium” frame at least I’m sure that I’m getting a good quality carbon fiber and someone actually thought for a moment about “tiny” details a place for VTX transmitter or battery strap…
So, please welcome DemonRC NOX5:
Since cameras like GoPro Session are heavy and my FPV goggles (Skyzone SKY-01) lacks built-in DVR, I’ve purchased DVR by Eachine: Eachine ProDVR. There is probably enough written on the web how it’s made and that it has problems with PAL signal and there are hacks to fix it. Oh well…
Instead, here are just some pros and cons, and short summary at the end. Continue reading Hands on: Eachine ProDVR
