On the paper, the Lanchi Monster 76 offers an amazing concentration of the last technologies into a 76mm towered X-frame. For example in the menu we have: a F4 Omnibus w/OSD flight controller, a strong 4-in-1 10A BLheli_S/Dshot 600 ESC board, 1104/8000Kv motors 48CH 25mW AIO FPV module, buzzer and programmable lights. Three variants are proposed. One PNP without receiver and two BNF with a FrSky D8 and a Flysky AFHDS-2A respectively. The machine is powered in 2S configurtion with a 500mAh LiPo. Let’s discover what can be potential super great machine.
The machine comes into a simple but solid box
+ 1 x Lanchi Monster 76^
+ 1 x 2S 500mAh/20C LiPo with JST connector
+ 1 x USB charging cable
+ 8′ x Spare props (2 CW, 2 CCW)
+ 1 x Instruction manual (English)
The instruction manual … is just so “light”… Miss all important informations, especially about the binding and the VTX setup.
The Monster 76 is a X-quadcopter with a elevated tower camera mount welcoming the AIO FPV camera module. At least we can find in the instruction a resume of all the main caracteristics. Notice that ESC can in theory support up to 4S LiPo… Insame. Unfortunatly, motor’s won’t :(…. They are already 8000Kv.
It’s confirmed to be a 76mm machine.
Good news, the main lower X-carbon structure looks strong and solid. The thickness is 2mm and for a such lightweight machine, it’s IMHO strong enought to handle most crashes.
All the electronic is well protected/integrated.jailed into the central section. No board in direct contact of crash. The lower 3K carbon frame looks very durable and 1104 motors also solidely installed on them.
For the FrSky D8 RX version, the receiver is installed just above the flight controller and below the camera carbon mount. Four pads can be nottced. From left to right: GND, +5V, SBUS, PPM. As you can see, out of the box, the FrSky receiver is configured with PPM connexion with the yellow wire soldered on the fourth pad (on the right).
The left side welcomes the main PWM connector for ESC.
Notice also how is attached to the main frame the camera tower mount. It’s clipsed latterally via a small carbon element. I am afraid during a big vertical crash directly on the mount that: i) in the best situation, the mount will be unclipsed and ii) in the worst, the carbon pad will break. For me this point is the weakest element of the machine.
Notice also the poor soldering job for all the ESC’s wires. It’s highly recommanded to add some liquid electrical tape to protect/re-inforce this part.
Two programmable lights are bounding the central buzzer. That’s great :). Notice also the microUSB port easy to access for Betaflight connexion.
The FrSky D8 present its binding button on the rear right part. You can access via a small twizzer or by the right button install on the top of the AIO camera module.
No real possibility to install props larger than 16mm … The remaining clearance is about 1mm with the DYS 1630 props.
A thin battery strap is pre-installed. No other velcro or anti-slip system to secure completly the battery installation.
79.5g… so one of the lightest model in the ~80mm category.
Motors and props
Some strong 1104 brushless motors announced to be 8000Kv….. IMHO, I would prefer maybe some 7300-7500Kv to run this beast in 3S setup.
The DYS 1630….. are known to introduce (a lot of) jello in video even I can reckon they are durable. Other props should be installed.
No specific mark of this battery offcially being a 500mAh 2S LiPo with 20C of discharge rate. 20C !!! is ridiculous for a racer. It will be confirmed later but the performances of this battery are really with massic voltage drop ending to a receiver brownout at the end of the flight.
No possibility to ajust it, but at least the AIO module is tilted about 20 degrees.
The lens offers a Field Of View of 120 degees. Perfect for both indoors/outdoors applications. The lens thread is in M7 format. The camera is basic but in practice good 700TVL CMOS camera. Actually the camera is locked in NTSC system.
One button can be found rear. If you short press on it you will cycle between the eight frequencies Inside the current selected Vband. If you long press on it, the blue light will flash. Then short press on it to cycle between the six supported Vband. As soon as the Vband is selected long press one more time to validate the Vband.

UNBOXING, ANALYSIS, BINDING, FIXING, CONFIGURATION AND DEMO FLIGHTS
The F4 onmibus is flashed with Betaflight 3.1.5. As exepected according the FrSky receiver connexion, the receiver is configured in PPM mode in betaflight. But first (deep) bad surprize, even if the pairing is correctly done between the TX and the RX (solid blue front light), you can’t observe any stick mouvements in betaflight…. 🙁 ??? Weird … The solution is already known…. turn the receiver in SBUS mode. You will need to unsolder the yellow signal wire from the fourth pad to the third free pad. It’s a 3min fix as showed in the video… nothing dramatic. Notice, the flysky version works out of the box. I regret the non-presence of the RSSI for both the telemetry and OSD…. For other settings, we have the default BF 3.1.5 ones…. no specific optimization have been done.
First take off and with a < 80g machine, as we could expect the machine is powerfull.... punch out are really good but!!!!! the super bad news comes from the battery.. Just after hovering, the voltage drops of 1.7v !!!! it's inacceptable !!!! Imagine for a punch out, it's more than 2V. The consequence can be dramatic with a receiver brownout. In practice it happens but at the end of the flight. Definitively, the first thing to change for the Monster is the LiPo and I highly recommend a model with at least 50C of discharge rate. With the current battery, the machine starts to buzz after only 10s. Even some local voltaage thresholds ajustement won't really help. Anyway, the machine flies great and smooth !!! It's a super fun, nimble and reactive model. Thanks to the F4@8Khz, lightweight. The AIO FPV camera works pretty well. Sharp and precize color, good light handling and good FPV range (~100m). You can notice some jello in the FPV signal associated with each throttle high inputs.... the guilty are the DYS props for sure. Another dispointed element is the flight time: 2min10 in average... far from the 4-6min advertized. At the end of each flight, the battery is super hot, another sign of the weakness/poor quality of the battery. After a crash from 5m high (linked with the receiver brownout associated with voltage drop of the battery), the camera mount has been unclipsed. No problem to re-attach it. I decided to moved to the 1535 quadriblade props from the Auroa68/Revenger 55. As expected the Jello is gone... and the machine is even more power. I installed a simple but light 400mAh/30C. Flight time is now of 2min 30. A guess a 500mAh with 50C... should be the perfect choice. I will probably use the Aurora 100 550mAh LiPo in the future.
The Lanchi Monster 76 is a super great and powerfull flyer thanks to its lightweight and strong/powerfull ESC/motors & FC. The frame is durable, the AIO module efficient. It’s almost the perfect compact machine but some modifications/improvements must be done: 1) Replace the battery for a 500mAh/50C, 2) replace DYS 1630 for the Racerstar 1535 and 3) for the FrSky version, turn the receiver in SBUS mode. Anyway, it’s one of the best model in this category.

The Boldclash B-05 is announced to be the lightest brushless FPV quadcopter thanks to a F3 tennyfish board, super light 0703 motors and 4-in-1 4A BLheli_S/Dshot 600 board. 32g with the battery is advertised!!! impressive, just slightly more heavier than a brushed TinyWhoops. For the FPV part, a 600TVL CMOS 48CH 25mW AIO FPV camera is installed. This machine is a direct competitor if the Eachine DustX58. Let’s check this new product.
+ 1 x Boldclash B-05
+ 1 x 350mAh 1S LiPo with microLOSI connector
+ 1 x USB charging cable
+ 8 x Spare props (4 CW, 4 CCW)
+ 1 x Screwdriver
+ 1 x Instruction manual (English)
The Boldclash B-05 is 66mm brushless racer with a builtin carbon prop guard. It employs an X-design with a lower carbon frame. The FPV AIO module is jailed into a super thin plastic canopy structure.
As you can see, the DustX58 is more compact, i.e. 58mm vs the 66mm of the B-05. In a first glance, we can see that the prop guard is much more thinner versus the Eachine version.
It’s confirmed, the thickness is only 0.5mm only !!!! versus 1mm for the Eachine. In practice this propguard looks super flexible… and the durability is an open question in a first glance. But in practice…. the guard resisted to all crashed I had….
The main lower carbon plate is 1.30mm so much more solid that the prop guard look like.
The look is pretty cool especially with the top canopy element. The props are the same than for the Eachine dustX58 and KingKong Tiny 7.
Installed front a super tiny button to bind the FrSky D8 builtin receiver.
With the antenna mod
The right side welcomes the microUSB port of the teenyfish F3 board. No problem to insert the USB cable.
The microLOSI connector.
The 4-in-1 4A ESC board.
With the rubber band to attach the battery.
22.3g standalone !!!! it’s close to 3g more lighter.
With the original battery 350mAh LiPo we reach 33.4g so 1.4g more heavier than the advertised 32g.
with a nanotech 500mAH LiPo
The same 0703 brushless motoro but only spinning @15000Kv versus the 20000Kv the dustX58. No real chance to run them in 2S configuration. In anycase the the ESC board won’t support 2S voltage.
The shaft diameter is 1.5mm. Notice the props are identical to the King Kong Tiny 7. In practice, there are known to introduce some Jello in the FPV link. Some other 30mm alternative can be prefered. For example the Eachine Revanger 55/Aurora 68 quadriblade props can be installed. Another alternative are the triblade husbsan props trimmed to 30mm.
A 350mAh model announced to be 25C…. After the end of each flight, the battery is pretty hot. Probably a model with 50C should be prefered.
The 600TVL CMOS 1/4″ camera coupled with a 25mW 48CH 5.8G VTX. The Field of View is fixed to 120 degrees so ideal for both indoors and outdoors applications.
In the read side, two buttons can be found. The front one if shortly pressed flip upside down the video signal. If long pressed you can cycle between NTSC and PAL systems. The rear button set the Vfreq and the Vband if shortly pressed or long pressed respectively.
UNBOXING, ANALYSIS, BINDING, CONFIGURATION AND DEMO FLIGHT
First good news, the TeenyFish F3 board is flashed with the last Betaflight 3.1.7. As for all F3fish board, you need first to plug the battery before to connect the FC with your USB cable in order to have working betaflight connexion. The FrSky D8 received is connected via Serial SBUS connexion. Good news, Dshot 600 is selected by default. No specific PIDs settings have been optimized for the B-05. Only the “angle” 6-axis stabilized flight mode is preconfigured. Since there is no builtin buzzer… you can play with the buzzer strenght in BLheli configurator to increase to buzz sound emitted after the period of inactivity. An indirect way to locate your lost machine.
As for the DustX58, the punch out of this machine are not impressive just a bit better what you can have with good brushed motors. Clearly the 0703 brushless motors are not yet the right answer for such light machines. Forget powerloops with this machine but it’s ok for basic flips and rolls in acro. Compared to the DustX58, the machine offers less bounce back/oscillations with the default Betaflight settings. So we can hope to have even better results witl some little optimization. That’s a good point. Unfortunatly, as expected with these props, some little jello can be noticed in the FPV signal. Probably the fist mod to do is to install better 30mm props. Compared to the DustX58, flight time are also much better. We have a solid 4min while with the dustX58, only 2min30 can be obtained with the 450mAh. With the Nanotech 500mah, 5min-5min30 can be obtained. Thats great. The machine is fast and very fun to fly in tiny spaces. Of course in strong wind conditions, the machine is deeply impacted. The FPV signal is good, in the average with this AIO module. For indoors flights, you can have super precize controls … it’s great. The FPV signal can cross several walls without difficulity so no problem to fly around all the house.
The devil is in the detail… and if the DustX58 and the B-05 are very close in term of electronic caracterics thanks to a lighter solution, the boldclash model offers much better flight time around 4min. This machine is not a super power acro machine, no miracle actually with 0703 brushless motors.. But it’s the B-05 is great indoors/outdoors machine super nible in tiny spaces. Better/lighter props and a better battery can boost even more performances.
+ 33.4g brushless FPV racer !!!
+ Indoors/outdoors machine
+ F3 Teenyfish board
+ FrSky D8 w/telemetry
+ Betaflight 3.1.7
+ 4min of flight time
+ BLheli_S/Dshot600 ESC
– Bit of jello in FPV signal
– Thin prop guard
– Not super powerfull for acro figures
– No buzzer
