TEST: JJRC H20 mini, another picohexacopter

Drone News

Recommended Posts



The nano/pico-quadcopter, hexacopter fashion year is not yet over. We have a new model from JJRC, a shrinked of their popular H20, i.e. JJRC H20 mini. All 2016 classic ingredients are here: headless, one key return but not altitulde hold and I think it’s good thing :). The H20 mini offer the possibility to swap the battery for a new one in a fraction of second… Let’s discover the details



+ 1 x JJRC H20 mini (with 2 x 1S 120mAh LiPo with mini-JST connector)
+ 1 x Transmitter (using 2xAAA batteries not included)
+ 1 x USB charging cable
+ 6 x Spare props (3 CW, 3 CCW)
+ 6 x Prop guards
+ 1 x Spare LiPo
+ 1 x Instruction manual (English/chinese)


In term of size, it’ 45mm machine, ultra tiny more a pico machine than a nano and comparable with the Fayee FY805.



For beginners, prop guards can be installed. They add only 0.3g


As said previously, the H20 mini is really a shrinkage of the H20 in term of design. No large and super bright LEDs unfortunatly. The blue lights are almost invisible in daylights and don’t help to keep orientation.




The mini-JST connector is here as well as a tiny switch. It’s always a good thing when a power switch is available.


The rear LEDs lights are weak too… and as for the front ones, don’t really help to keep orientation




A battery bay to welcome the LiPo


The LiPo fills all the battery compartement. No real possibility to install a more stronger model, maybe a 150mah maxiumum.



12.6g … with the battery super light!!! Don’t expect miracle for outdoors flights even with a very small breeze.




Motors are 4mmx12mm coreless motors, the smallest size available for such motors.


1 cell LiPo 120mAh with 20C for discharge rate. The battery uses 1.25mm mini-JST connector with inverted polarities… So don’t mix your H20 mini batteries with some other. You can have big troubles



A gamepad style radio but nice to grab. Sticks are clearly adapted for thumbers… No pinchers extra sticks in the bundle.
The left sticks when clicked on turns on/off the headless mode. The rear light blinks correspondively. For the right stick, it’s the one key return…. in practice as usual a return to somewhere. The top left panel button selects one of the three speed mode. The ultimate ones offers the same rate as for the intermediate except for the yaw rate…., the machines spins crazy in this mode adapted to played with headless mode. The top right activates manual flips. The bottom right permits to calibrate gyros/accelero.


In the rear compartement, you can recharge the quadcopter LiPo. It takes 20-30mm for the job. It’s perfect, if you far from any wall socket/USB port.


The total weight is pretty light ideal for transportation, office break, etc…


I tried without success to bind & control machine with all DeviationTX XN297 protocols based. In fact, I believe the H8-3D protocol binds the machine but you can’t control :(…. So a little modification of this protocol should be done to hack it.


The machine flies beautifully and stable. Rates are well tuned even the last with the headless mode turned one. The flight time is good, more than 5min. When LVC alarms is here, the LiPo is @3.5V. So don’t abuse of flight machine in LVC conditions. The lights are not so visible and beyond 10m it’s hard to keep your orientation. The machine is not ultra sporty despite the presence of six motors. Punchout are limited. As said previously, it’s a beginner machine but fun & stable to fly with.


The JJRC H20 mini is first of all good picohexacopter, without major bad points. Clearly targetting beginners, the machine is durable, easy to fly and offer a spare battery to extend your pleasure. The price is also good and the H20 mini can represent the typical little techgift for Xmas.


+ Full transportable nanohexacopter
+ Durable machine
+ 3 well tuned speed modes
+ Removable LiPo
+ Spare LiPo
+ 5min if flight time
+ Possibility to recharge batteries via the transmitter
+ Cheap


– Unicolor props
– Poor LEDs visibility
– YaP (Yet another protocol)
– Not outdoors machine
