TEST: KingKong Tiny7 (44.4g, SPF3 w/BF, 0720 motors, 800TVL/150deg 16CH/25mW AIO)

null

INTRODUCTION

Main drawbacks associated with tinywhoop FPV machines are probably the poor flight time and the lack of power thrust in order to be 100% acro compatible. KingKong with the KingKong Tiny7 introduces a larger 75mm variant but with 7mmx20mm coreless motors. It’s the big brother of the KingKong Tiny6. Of course the machine will be more heavy but in another hand more powerfull too. With this new 75mm model, we have also a powerfull SPF3 flight controller including a buitin 25mW 16CH 5.8G VTX with linear antenna. The standalone FPV camera is a 800TVL CMOS PAL model. Four type of receivers are proposed: Futaba SFHSS, FrSky D8, Spektrum DSM2/X and FlySky AFHDS-2A. Mine is the FrSky D8 version. Let’s try to answer to this question ….

BOX CONTENT

For the Deluxe edition, the machine is shipped with this nice and durable plastic box, the same box as for the Tiny7 or the GT90.

OVERVIEW

The Tiny7 is a 75mm larger variant of the Tiny6 basically, largely inspired from the TinuWhoop ducted machine with a upper canopy element jailing and protecting the FPV rig.

null

If the design between the Tiny6 and Tiny7 shares 95% of elements, the difference can be found in the propguard shape, more precisely in the front part where now a plastic element reinforcing the structure is present. If the durability and the general quality build seems great, the central element will block partially the field of view for FPV.

null

-FRONT VIEW
As you can see, all capital elements are very well protected either by the ducted system or the top canopy

null

-SIDE VIEW
The 5.8G linear antenna is this thin copper wire. You need defitively to install it vertically but the furthest of the rear 2.4G antenna.

null

-REAR VIEW
null

The FrSKy D8 AC800 can be guess through to canopy. More the two LEDs associated with the VTX channel selection are very bright and can be seen in daylight conditions. Via a thin tip you perfectly select your favorite Vfreq without removing the top canopy part.

null

-UPPER VIEW
null

-BOTTOM VIEW
Like the Tiny6, the microUSB port for Betaflight connexion is located bottom … and even of it’s possible to run accelerometer/gryos calibration via stick commands (desarmed)… it’s pretty annoying to level the machine when a microUSB cable is plugged.

null

null

Main F3 ARM MCU and 6-axis stablization chip are installed on the bottom side of the PCB.

-WEIGHT
null

null

Motors and props

Some 7mmx20mm coreless motors. Any indication about corresponding RPM but in general the trade off between weight/thrust is in favor of the Tiny7 versus the Tiny6.

null

Slightlty larger triblades props (~40mm)

null

LiPo

Strong 500mAh/30C LiPo with 2mm microJST connector

null

null

null

null

Camera module

null

A 800TVL CMOS FPV camera emitting in PAL system. The Field Of view is around 150 deg, a good choice for indoors flights

null

The AIO module is directly taped on the top canopy section

null

Notice the VTX offers only “16” channels divided into 4 differents bands. Two buttons can be found on the FC. One is related to the boot rescue option and the second is related to the Vfreq selection according the following color’s table

null

You will have to cycle between the 16ch one by one…. In general, I find this selection system easy.

Disassembling

null

Like the Tiny6, the FC+VTX combo is installed on little rubber O-ring to decrease vibration’s impact transmitter by motors. The back wire is the 2.4G antenna while the naked copper one is the 5.8G antenna associated with the builtin VTX. The lenght if the 5.8G’s wire is about 31mm corresponding approximatively to 5/8 of wavelength. Notice the FPV camera’s wires are directly soldered on the FC… We could expect a tiny 3positions connector instead.

null

Despite being rotated of 45 degrees, the FC don’t any specific alignement in Betaflight. The MCU is an SPF3 model strong enough to stabilize perfectly the machine and enjoy >= 4Khz PID loop time.. Installed on top, the AC800 FrSky D8 compatible receiver. No binding button, the receiver enters into an autobind mode after 6s (red led flashes fast). The AC800 is unfortunatly known to present some sporatic glitches in controls… At least the RSSI is broadcasted via telemetry.

null

UNBOXING, ANALYSIS, BINDING, CONFIGURATION AND DEMO FLIGHT

The SPF3 board comes with BF3.0.1 pre-installed and from now it’s advized to upgrade for a more recent build to enjoy better optimization, performances. As for the Tiny6, I had to update a bit PIDs settings. I used the same as for the Tiny6 and it’s flying great with

null

The Tiny7 is little but more powerfull than the 65mm variant, starts to hover from 40-45%. As expected, the FOV is more limited by the new central propguard part 🙁 Anyway, the FPV camera offers pretty good results …. the 25mW VTX is correct but not among the best in term of FPV range versus for example some Eachine AIO models. The machine flies smoothly for indoors application… and you can really fly in super tiny spaces too….The Tiny7 is super crash resistant…. indestructable almost. The main positive point at least versus the Tiny6, the tiny7 is more Wind resistant and can fly correctly outdoors. It’s relatively fast … We can maybe regret the absence of a builtin buzzer. The flight time is great, more than 5min. With the AC800, I have some sporadic little glitches in controls… With deadbands, bad side efect is fortunatly limited.

CONCLUSIONS

A great indoors but also outdoors compatible FPV brushed racer. The quaility and durability are probably the main positivie pros points. In fact, there is not really weak element… The F3 is powerfull enough to run betaflight smoothly, flight time are great… maybe the FPV link don’t allow flight above 60m … The Deluxe bundle is great with ton of batteries, a great parallel charger…. Maybe you can regret the absence of spare motors. Both Tiny6 and Tiny7 are definitively recommended products…. but for me maybe the Tiny7 is little bit more interesting since it’s more outdoors friendly.

PROS

+ Quality build
+ Great FPV indoors/outdoors machine
+ Good FPV camera
+ >5min of flight time
+ SPF3 board w/ Betaflight 3.0.1
+ FPV camera protected from crashes
+ Nice packaging for the deluxe edition
+ Durable/robust to crash
+ FrSky D8 receiver with RSSI

CONS

– FOV more limited by the propguard than for the Tiny6
– No builtin buzzer
– MicroUSB port location
– AC800 receiver with potential sporadic control glitches

    Salut Seby, Je dis comme toi +1 avec les moteurs 7X20mm pour pouvoir voler dehors. 🙂

    I use the DSM2 version and the only issue I had was the receiver was doa. I swapped it out and got up the air no prob. Definitely more than than a whoop. I get 4-6 mins of flight as we’ll depending on if I’m chillin or really flying through my house. I definitely recommend!👍

  • hay seby
    i plan to buy this little guys
    i have brand new jumper radio t8sg
    so i need your advice here
    what kind receiver should i buy ?
    and how to connect with it
    i hope you answer 😀
