This is part 2 of my review of the Leader 120 by Full Speed from Gearbest. For part 1 click here. As at September 2017 try code HarvestRCnew7 to get this for only $US93.99!  None of the dreaded "brown outs" here Straight up I have had none of the reported issues of brownouts as many of the youtube reviewers found on the first version of the Leader 120. In saying that my review modelis version 2 which I has the fullspeed branded black motors. The default idle speed of which there was a lot of chatter about was set at 10% from the factory in Betaflight 3.1.7. This is very high and reducing it to my regular 3.5% caused no issues. So on to the more interesting stuff! Flight characteristics This is a great little flier, As I expected from hearing the motors run in betaflight they are very quiet and coupled with the well-balanced KK 2840 props it lets off very little noise in flight. Coupled with the size, this makes it much more socially acceptable to be flying in areas that aren't completed isolated. The rates are not stock either and I actually really liked them, even compared to my stock betaflight 3.2.0 settings when I flew my 5" quad immediately afterwards. There are an awful lot of micros that have poor or no tuning from the factory so was escpecially pleased when the tuning here required practically nothing for those either lacking the know-how or too lazy to do. Power is excellent on 2s and comparable to many 2" quads on the 3s - the bigger props and relatively light weight really make these motors come alive. Handling was predicatable and I felt I had good control even in heavy gusts.  Stock battery The stock battery can be described as adequate. I can see the voltage alarms were set low at 3.0 warning, 2.9 critical to allow for the sag but it keeps you in the air with moderate flying for up to 4 minutes. Considering I was able to flow without esc desync, losing vtx signal or getting failsafe, this probably makes it better than 90% of included batteries out there (not kidding). I'll have a follow up tips and tricks article soon where I look at some of the other internationally available battery options including 3s. FPV - Camera and VTX Ahh a chink in the armour. Hitting a sharp price point eventually means compromise and I think I've found it. Typical of All In One (AIO) cameras this handled low light on a dull day poorly even with the focus correct. Kind of makes branches jump out at you when flying under trees - that's my excuse anyway. Secondly although the VTX does well enough for 25mW, it still only does 25mW. That means that I started seeing breakup at 100-150M away or as soon as I was on the wrong side of even small trees. The good news is you can pop this on your RC car or tiny whoop (I STRONGLY recommed the Eachine E011) and upgrade this one. There is more than enough lift for the extra weight of a micro CCD camera like the Foxeer arrow micro or Runcam swift micro and a Vtx like the new one from fullspeed that is 25mW/200mW switchable to mount on the back. I'll be making such a change in the near future and reporting back in a new article in the tips and tricks section.
Early conclusions
This model is an amazing combination of well-matched parts with good assembly and a custom tune making it compelling on paper. I'm pleased to say that this transfers into flight characteristics and power making it an option you should definitely be considering if looking at a micro in 2017. I personally think this frame size that allows for a 2.8" prop rather than 2" is much better matched to this motor size and not nearly so sensitive to weight meaning for a more robust and enjoyable flying experience. My only real gripe is the video quality where camera light handling and vtx power lets it down. It is hard to argue at this price point though and in a future article I'll be doing a budget mod to address this. Most interestingly, I built a model from parts that was very similar to this before this model was announced. Cutting to the chase the PNP version from Gearbest was more quiet and felt more solid in the air (perhaps due to the tune/rates) than my own build. Power was similar: although noisier I think the DYS motors had an edge although for the small difference I prefered the ones in this PNP model. I preferred the adjustible power vtx on the model I built to bump up power but this is really starting to split hairs. This does have me second guessing my build vs buy strategy but I think this is testament to the well thought out component list Full Speed have chosen. Buy the Leader 120 from Gearbest
