Be aware, all weight informations given in the video are not in grams…. sorry for my mistake. Correct weights are given below

INTRODUCTION

The Boldclash B06 is a new brushless TinyWhoop class FPV racer, the direct successor of their former Boldclash B05. With this new model, bye-bye the TeenyFish F3, they prefered to return to classic SPracing F3 board. Motors are still some 0703 but for the B06 they are announced to spin at 15000Kv. The FPV rig has been also updated. Now a 800TVL CMOS 1/3″ 25mW 48CH is integrated offering better light performances versus their former 600TVL camera. The FC includes also 4-in-1 ESC solution but now only “2A” (peak@3A) BLheli/oneshot125 but no more BLheli_S/Dhsot compatible. Actually four choices of receiver are proposed: FrSky D16 XM, FlySky AFHDS-2A, Spektrum DSM2/X and Futaba FASTT. There is also a PNP variant. Let’s discover this new model

+ 1 x Boldclash B06
+ 1 x 1S 450mAh LiPo with mcpx JST pH 2.0mm connector
+ 1 x Spare top canopy
+ 1 x USB charger
+ 8 x Spare props (4 CW, 4 CCW)
+ 1 x Wrench prop remover
+ 1 x USB to microUSB cable
+ 1 x Instruction manual (English/Chinese)

OVERVIEW

The new B06 is now full plastic based. No more carbon element. Paradoxally, the ducted/prop guard system looks much more robust and by consequence it’s not a bad news. We have no more the tall central FPV tower potentially breakable during a crash. Here it’s more a lower profiled canopy structure, much more robust.

null

Even it’s not obvious on the photos, the B06 is a 75mm machine so 10mm more larger than the B05.

null

-FRONT VIEW
The design is cool more similar to the original inductrix/King Kong one. The FPV solution is now fully protected with this strong plastic canopy structure. It’s nothing else than the F06 FPV solution, I recently reviewed.

null

with the battery installed beneath playing the role of landing skid

null

-SIDE VIEW
null

Any visible latteral port. Everything look highly profiled

null

The camera is installed with an positive inclinaison of 15 degrees. Since the B06 is suitable for both indoors and oudoors applications, this angle’s choice is a good one IMHO.

null

-REAR VIEW
The linear antenna installed horizontally. In practice, the FPV range is pretty good so some even better results could be obtained if the antenna would be installed more vertically.

null

-UPPER VIEW
One unique button, i.e. the Vfreq/Vband selection button. One short press to cycle between the eight frequencies inside the current Vband and press & hold more than 2s to cycle between the six supported Bands. Notice, you can guess a sliding blue light for the Vfreq selection and a sliding green light for Vband through the canopy.

null

-BOTTOM VIEW
Even the X-structure arms are in plastic. I was worried at beginning but in practice they are super robust and the lightweight of the B06 helps a lot in their durability.

null

We can guess bottom the microUSB port for Betaflight connection and the receiver just below the battery bay.

null

The FrSky XM receiver is installed beneath… with the 2.4G antenna parallel to the main FC board and in sandwish with the LiPo. There is a super tiny bind button. Press and hold it while powering the machine then run the binding procedure on your compatible D16 radio. It’s a bit tricky to do it with only two hands. It’s a basic FrSky XM module so without telemetry feedback. You can flash it with a new firmware to send the RSSI value on the last channel but since there is no OSD, it’s in practice useless to do it.

null

Clearly the location of the receiver is far to be ideal in term of the radio reception. The best would be to install the receiver on top with the antenna more vertically. It should be possible to mod the position in this way.

Good news for motor’s maintenance, they are connected to the main board via 3 positions microJST connectors

null

-WEIGHT

26.5g standalone

null

in comparaison with the 22.4g for the B05

null

With the battery installed, we have a total weight of 40.4g

null

versus the 33.5 for the former edition, so a difference of 7g.

null

3g can be explained by the 450mAh LiPo versus the 350mAh. So the other 4g comes from ducted system and the heavier top canopy structure. The main open question, will these 7 extra grams will impact deeply the flight caracteristics.

Motors and props

0703 motors “racing edition”, boldclash branded announced to be 15000Kv. No information about their associated thrust… shoud turn about 20g each.

null

They are the same as for the B05.

null

Some 40mm triblades props, the same than for the B05

null

LiPo

They upgraded the LiPo from a 350mAh to a 450mAh and more a 25C to a 80C for the discharge rate. Now the open question, are these new number true ?. They decided to move from a microLOSI connector to a JST pH. Judiscious choice ? More, I notice the gauge of the main lead power cable relatively thin…. IMHO it should impact negatively the performances of the machine.

UNBOXING, ANALYSIS, BINDING, CONFIGURATION AND DEMO FLIGHT

The machine comes with Betaflight BF 3.1.6 (dump file) and correctly configured at least for the receiver section. It’s not the ultimate one and better results could be obtained with the last BF3.2.1. At least, I would say, no ton of extra work is required with the B06. After the binding, you can enjoy directly the machine. By default, the machine is armed with AUX1=CH5 and only the angle (6-axis stablization) mode is set. So if you want acro, you will need to modify by yourself, the flight mode section (see video). Since there is not buzzer, they set the beacon delay & volume to 2min and max respectively as I recommended to them during the beta stage developpement. The BLheli firmware installed is the 14.6. I don’t think flashing the last 14.9 can turn ESC BLheli_S compatible. The buzz emitted is strong enough to hear to machine within a radius of 3-4m… which not bad. Of course we can regret the absence of a very tiny 0.7g buzzer….. one of the first mod to do. I think some little plastic element can be removed to gain some weight. In this case, the buzzer installation should be extra gram free.

Immediadly, you can notice than the FPV feedback is good espcially for a CMOS camera. Light sensitivity is better than the average. The FPV range is also good despite a linear antenna.

You can cross 3-4 walls indoors without problems without tons of breakup. Absoluptly no drift can be reported in angle mode !!! You can have super precise indoors flight with ultra precision. Very fun. For outdoors, throttle punchouts are oviously impacted by these 7 extra grams even if the 80C battery probably compensate most of. Don’t worry the ascent rate is very acceptable but it’s far to reach a 3S machine performances. At least, you can enjoy acro figures without problem but you probably will loose a bit of altitude. It’s for sure far better than any brushed competitors. I would like to use this battery on the former B05 model. Should boost well performances as well. Despite being installed horizontally, the 2.4G control range is good in a radius of 100m. Any dropout reported. 4min of flight time can be achieved with this excellent battery. After the flight, the battery is even not warm… A good sign of its quality.

CONCLUSIONS

One more time, Boldclash delivered a good product…. and in term of flight caracteristic, this brushless machine is very efficient indoors and outdoors. The FPV, control ranges are good, the battery autonomy good. The structure is durable….. almost the perfect machine…. but I would prefer to a see a builtin OSD…. the Maxvideo chip should add only 0.2g for the SPracing F3 board. Probably we will see it a next model. I think with these model we achieve the limit of 0703 motors can give. To boost even more performances, maybe 0704 motors is the way to go.

    bonjour
    penses tu que c’est une bonne idée (et faisable) de ne prendre que la frame et installer des moteurs 1103 ainsi qu’une autre carte de vol et esc 16 par 16?

    • SeByDocKy says:

      I will answer in english. I think 1103 motors are too large for such 75mm frame 🙁 … and there are close to 2.5x more heavier as well 🙁 More the current ESC are only 2A.
      1103 motors are more suitable from 90mm frame IMHO.
