The Furibee X140 is a traditional style 3 inch quadcopter as opposed to a lightweight 3 inch like the Leader 120. It is available as a Plug N Play (PNP) with no receiver or as a Bind N Fly (BNF) with either a flysky receiver, frsky receiver or futaba receiver.
Some of the key features of this quad are:
The box it came in is small brown and very boring which is good because on a budget quad I don't want to be wasting my money on that. What I am most happy about are the components:
FPV: Micro CCD and switchable VTX
They key points for me is that this has a real CCD camera (Furibee micro) and a vtx that is switchable between 25mW and 150mW. I'll cut to the chase and say the camera is excellent and like the HGLRC elf which also appears to be a clone of the micro swift, you would not be able to tell the difference. Combined with the VTX this 'hits' the right FPV feed where other micros miss.
Frame: Good luck trying to break this one.
Straight up the frame is a tank. It uses separate 4mm thick double chamfered replaceable indicular arms and is incredibly stiff. It has been designed in the streched - x style (less space between left and right motors than front and rear) which gives better pitch fine control and less turbulent air to the rear props in forward flight. One challenge with the streched X is that props are in full view in FPV (like the floss 2 frame) but a taller set of standoffs and camera mounts elevates the camera mostly above the prop disc line making for a nice FPV view. It is not a light fram however because of this but is crazy durable. I don't doubt gearbest will be listing arms soon but don't think they will be selling many...
Electronics: Well balanced
Really glad they went with 20mm x 20mm here, I really think this is the way of the future. I'm even trialling a 20mm x 20mm stack in my 5" race build here. Flight controller is an Omnibus F3 with betaflight OSD, a proven unit. ESC is 20a which will have no problem on this quad even if you put much bigger motors on. Best part is that it is 4s capable. Also it is nice they included a real buzzer/led combo. Buzzer is handy but not vital now that we have the motor buzzer on betaflight 3.2.0 and up. Leds are nice and connected to the DIN so there is are limitless options for how you wish for these to light up. Nice to have but in truth I'll probably remove to try save some weight (4g for this unit).
Motors: Efficient but need a 4s battery
It's a good thing that the ESC can do 4s because I feel a 4s battery is really needed since the motors are of a fairly low kV (3100kV) They should however offer excellent flight time (update in part 2 review: they do). For the record they are Ready to Sky branded 1306 3100kV motors that appear to have smooth bearings and no obvious visual defects.
Propellers: Easy upgrade here
The props included are 4-bladed 3030 meaning they are 3.0inch with a 30° pitch. This is a fairly low pitch, ESPECIALLY for the 3100kV motors. They will get you flying but when you get replacement I would definitely go for something more aggressive like the excellent Gemfan Flash 3052. I think this will be an excellent upgrade and will make a 3s battery more relevant.
Weight: Bit of a tank
This is not a light quad at 125g dry (no battery). By comparison the Leader 120 was 64g but this is a different class of micro with bigger motors, much more durable frame and superior FPV camera/vtx. In addition it will lug a 4s battery unlike the leader which is 2s or 3s at a stretch. I'd expect this to be more "chuckable" than the leader which has more "floaty" flight characteristics.
Betaflight 3.1.7 came sock on this flight controller. After looking through the settings it was dead stock without even an arm switch set up. Rather than setting up and flying on 3.1.7 I jumped straight to 3.2.1 which is the latest release at time of writing. It is a step change improvement - in particular dynamic filters. Below is a gallery of screens where I changed setting from stock. Clich through and see the captions to help with your own setup.
Early pre-flight conclusions
I really like the components on this one especially at the price point ($105 currently for PNP on the discounts page). I think it was unecessary to build the frame with removable arms and heavy 4mm thick ones at that. Micro quads tend to be more crash resistant because they are lighter so this looks like an overkill. In saying that it should be VERY VERY durable and should offer good flight times with the more effcient low kV motors it has. I'll comment after part 2 of this review on mods but I have a few in mind that should really make this move.
