I'm pleased with this model. It flies well, although the CG as stated in the manual is wrong. After experimenting a little I set it at about 55mm, 10mm forward of where it's allegedly supposed to be. This improved matters quite a lot. The large balloon wheels make takeoff from uneven ground much easier and also make landings better. Note that it has a tendency, due to the high thrust line, to tip the nose down on takeoff. I found that you need to hold in a little elevator to keep the nose level, accelerate fairly slowly until it's rolling well, THEN give it full power for a takeoff. If you do that it's very smooth, if you just go for it you'll faceplant the thing! Once in the air it's really not bad at all. I've got mine currently configured with a 4s 5000mAh lipo shoved as far forward as possible in the fuselage, which still required some 200g of extra weight in the nose to get the CG correct, and that will allow more than 25 minutes of flying. You only need at most half throttle to cruise around with this configuration. I did replace the supplied ESC with a 60A Aerostar WiFi one as I like them due to them being very smooth indeed, but it flies fine on the one that it comes with. You could EASILY double or even triple the battery capacity for long flights, the fuselage is huge and has lots of space inside. And there are camera mounting points all over the place. On the whole I'm impressed, it's the usual standard of design I've come to expect from Volantex, and the only bad point is the normal problem of Banggood not packing this sort of thing as well as they could. That said it arrived undamaged so I can't complain!

These antennae are labeled RHCP, or at least the ones I got were. As any DJI user will know, DJI use LEFT hand polarised antennae, and a right handed one won't work properly with their system, producing at best a drastically reduced range. I was unsure whether they were actually the correct antenna with bad labelling or the wrong one with correct labelling when I got them, but after a test I can say it's the first case. Despite what's written on the top, these are LHCP antenna, and they work very well indeed. I found the range to be at least as good, if not better than, the original DJI ones. I was using them with an Ocusync transmitter and camera in a custom drone, with a DJI Racing Edition goggle set, and they're absolutely fine with it. Good quality, well made, and efficient.

Truly excellent little soldering iron. Reflash it with the upgraded software which you can easily find with a google search. It's not hard and it allows a number of useful extra features. I do an awful lot of soldering as it's part of my work and I'd rate this device as easily up to most of the high end bench soldering irons I've used. I'd recommend getting a pack of different tips too, as there's nothing worse than finding out you don't have the right one when you're working on something!

My third Ender 3, and as good as the other two. They're fairly basic printers, but they pretty much work perfectly out of the box and are generally reliable. I would highly recommend replacing the bed springs with stiffer ones, which are readily available very cheaply all over the place, and it's probably worth upgrading the extruder feed mechanism with a third party metal one if you do a lot of printing as the plastic one it comes with will eventually wear to the point it misfeeds. But those are fairly minor points that are easily sorted out, and overall the Ender 3 is a very good entry level printer. My first one took me one and a half hours from opening the box to doing a test print. By the time I'd assembled three that was down to 50 minutes. I timed it :)
