Eachine E010S

So I was flying this little micro copter for a few days now and I have to say it is amazing for flying at home. I installed Betaflight 3.2.2 immediately on it and found perfect settings for it so it flies really well (check out my screenshots in the gallery below).

The PIDs are surprisingly high but it seems this is needed for brushed micro quads.

I really recommend the following to enjoy flying over the winter days.
– Do not install the canopy and fly with as little weight as possible.
– Use the rubbers to keep VTX and cam from falling off after hard landings.
– Buy more LiPos and a multi charger to charge more and fast.
– Buy few spare props.

The Review

You probably already watched the video and you already know how good looking the JJRC H43WH is. It’s made of ABS and stiff so it will be hard to break but keep in mind that it’s not made of carbon so you better not fly it full speed into a wall.

I was surprised how stable the little quad is because I was testing similar toys in the past and it was pretty damn hard to keep them hovering above the ground. There is a small drift to the sides but you can pretty much get rid of it by using the trims inside the mobile app. So to get started flying the crab you basically just charge the battery over the USB charger, download the mobile app, connect the app to the drone and use the touch screen of your phone to fly it. You use touch buttons to steer in all directions, make it do flips and rolls. There are also buttons for taking of, landing. Please be aware that you shouldn’t fly it further away than 30 meters, keep in mind that it’s being controlled over WIFI. The quad copter is harder to steer when it’s windy so take this into consideration when going outside.

You can take photos with the crab and also record videos. Everything is saved nicely through the mobile app on the phone. I was using an iPhone 6 for my review and everything was working just fine. The little camera inside is 720p so has a frame size of 1280 by 720 pixels. It records with 25 frames per second and with a bitrate of 1405kbps. The quality of the photos and videos is obviously nothing special but what would you expect for this amount of money anyway.

The battery is a small 1S 500mAh battery and it takes about one hour to charge it. It lasts only 5 minutes so if you plan to take the little guy for a hike I suggest to purchase more batteries.

If you transport your drone folded you need only 38 by 150 by 96 millimeters. Unfolded it takes 150 by 150 by 27 millimeters. It’s light with 75 grams (including battery).

I’d say that for just USD37.99 it’s a pretty good deal for people who just want to take a sneak peek on playing with quad copter toys.

Wraith32

Airbot is the very first manufacturer with the 35A rated and DSHOT1200 capable BLHeli_32 ESCs.

The potential KISS ESC killer is 32bit based and runs a Cortex-M0 at 48MHz. This should allow the ESCs to be extremely efficient and run motors as smooth as never before. The ESCs are packed with features like auto timing, voltage and current limiting and even telemetry.

Specification

  • designed for 35A
  • 2-6s capable
  • includes current sensor
  • small sized with 15*30mm (31mm including signal and GND pads)
  • RGB LED inside

The Build

My kwad with the Wraith32 ESCs will be built out of following parts.

Follow the BLHeli_32 thread @ RCGroups for more information.

Build In Progress

Quality of the ESCs is very good, as usual for Airbot’s products. The golden plated pads are super easy to solder. I’ll probably turn over the ESCs and solder the motors on the other side because then I don’t have to cross + and – wires on my PDB.

Airbot mentioned that adding some tin to the long pad on the side will increase current capacity so I’ll do that as well.

The Wraith32 ESC are longer than KISS ESCs or Racerstar 30A V2 ESCs and it has to be taken into account (they’re also about 6mm thick). I wanted to make motor wires a bit longer and it’s now a pretty tight fit on the arms. The RGB LED is now on the bottom of the ESCs but it’s easier to connect them to the PDB for me that way.

The FC is soldered and the new BLHeli 31.3.0.1 works well. The ESCs get recognized as “Airbot_Wrait32_ST”. Current Betaflight 3.1.7 does not have the necessary code for the pass through function so the one from RCGroups thread has to be flashed.

I don’t recommend flashing the pre-production ESCs with Airbot_Wraith32_ST_Multi_31_2.Hex. I just bricked my ESC #1.

The Video

Take a look at the following video in which I compare HD footage to DVR footage from Fatsharks. I additionally compare DVR footage from Eachine BAT QX105 and the Eachine DVR03.

Summary

Good for recording 720p @ 30fps HD footage in air crafts but definitely not for FPV racing.

The Good

  • Unreal amount of features, including power switchable VTX and micro card slot for recording DVR video.
  • Extremely easy to set up over buttons with LCD screen and OSD.
  • Comes with a microphone.

The Ugly

  • HD video quality could be slightly better.
  • Sharpness could be set slightly better.
  • Gets very hot.

The Bad

  • The worst thing on this AIO camera is the latency for FPV goggles. It’s huge (unusable while recording HD) and therefore the camera can’t be used for FPV racing on micro quads.

Eachine QX105 BAT Review

Now I’m 150% sure that you can’t fly this quad inside a small flat like mine. It’s lightning fast and mostly suited for outside action or extra large rooms.

You like what you see? Buy the QX105 BAT @ Banggood!

Features

This little speeding machine features very *very* powerful 1020 core less motors (black edition). It comes with built in receiver (FrSky, DSMX/DSM2 or FlySky) and an AIO FPV module with 25mW VTX with 48 channels and a 600TVL CMOS camera (M7 lens with 120 degrees field of view) with adjustable angle (how cool is that? ;)). The most exciting feature however is the built-in Betaflight OSD and telemetry output which I never saw on a micro quad like this.

And did you see those pictures? The quad looks extremely cool and it has configurable LEDs! 😀

Accessories

  • 2 spare motors
  • 4 spare props (2x CW and 2xCCW)
  • 2 600mAh Eachine batteries
  • USB charger
  • split wire for parallel charging of 2 batteries
  • prop removal tool
  • velcro tape for attaching batteries
  • user guide

Dimensions

  • Kwad itself weights 56g.
  • With battery 71g.
  • The frame is extremely durable, it’s 1.6mm thick. I crashed it many times on concrete and against trees but it still flies great without hiccups.
  • The battery is 14g and 24 by 45mm.
  • Propellers are 66mm long and extremely durable.
  • One motor is 7g.

Firmware

I flashed newest BFL 3.1.1 and I recommend to flash this version as soon as the quad arrives. The target was OMNIBUS and one can pretty much leave all PIDs as they are but for my taste RC rate must be increased. The QX105 can be flashed without pressing any buttons on the flight controller because the boards jumps into DFU mode automatically.

Flying

Well… see for yourself. I can’t believe how fast that little guy is. It’s outstanding! I used and abused the QX105 and crashed it against trees, on concrete and “landed” it in snow many times but it still flies very well.

Configuration/PIDs

My Betaflight 3.1.1 settings can be downloaded from here.

Battery

The Eachine batteries are really annoying when it comes to holding the voltage. It sags constantly and makes the beeper go crazy all the time so I suggest to deactivate the beeper for voltage alarms. This can be done in Betaflight with the following commands.

beeper BAT_CRIT_LOW
beeper BAT_LOW

I did not react to the voltage warning and just landed the quad after 5 minutes of hard flying with the 600mAh Eachine LiPos.

Summary

It’s a great, durable and extremely fast outdoor quad for beginners and advanced pilots. The fun starts when you push the throttle really hard. Definitely buy this kwad!

The Good

Things that are fantastic about the kwad.

  • Very well designed and cleanly build quad. Great for playing outside.
  • Good FPV AIO  module.
  • Receiver already inside the flight controller.
  • Powerful motors
  • F3 MCU
  • Betaflight OSD
  • MPU6000 GYRO connected via SPI

The Ugly

Things that could get better.

  • It’s not a deal breaker but only RSSI is sent via telemetry to your Taranis. I’d love to at least have voltage so Taranis tells me when to land.
  • ESC connectors pop out when landing or crashing sometimes so you have to use some silicone (or better some super glue) to fix them.

The Bad

Things that absolutely need to be fixed.

  • The batteries are not great. The voltage drops almost instantly to values around 3.5V and below and Betaflight beeps the hell out of the FC. Please Eachine give your customers much better batteries.

Airbot Omnibus F3 Mini

Well… airbot did it again. They released this really cool AIO board (including PDB and OSD) for micro quads which are really nice for flying at home in the winter. I finally found time to take a first look at it and I think I’ll design a 3D printed frame around this cool flight controller because I currently have no idea which frame would fit the 25mmx25mm (mounting holes) board.

It’s insane if you look at the features of this little but powerful guy.

  • STM32 F303 MCU which runs Betaflight (there is a F4 version around as well)
  • SBUS/PPM input + DSMX port
  • 4x motor output pins
  • SPI sensor MPU6000
  • SD card slot
  • current sensor
  • barometer BMP280

So let me state this clearly. You get this small AIO board which includes the FC + Betaflight OSD + PDB (up to 2S direct battery input) + SD card slot for black box recording for just about fifty bucks.

What other components to use with this board? Well I already ordered this Racerstar 6A ESCs and 8000KV motor combination. Now just have to design the 3D ABS printed frame.

EACHINE E10WD

The EACHINE E10WD can be purchased here.

Pretty amazing little quad that I received from Banggood. It behaves really well in the air. It has a camera but you can’t really fly FPV with it because of the delay you are getting on your phone attached to the remote control. Eachine even created a mobile app for recording video and taking photos. You get about 2 minutes of fast flying with lots of flips.

PROs
– handles very well in the air and can help learning flying line of sight
– small and absolutely flyable at home
– prop guards so you can’t hurt people
– very fast
– spare props inside the package
– no additional transmitter needed
– can flip on button push
– nice leds look really awesome

CONs
– not for FPV because of the delay
– only 1 battery included but it’s so much fun that you need more

Package includes the following parts.

1x E10WD itself
1x 3.7V 150mAh battery
1x transmitter
4x spare blades
1x USB charging cable
1x manual

TBS Powercube Elite Bundle

It has arrived in the stores and I wanted to take a look at it because it’s flat and includes so many components (check out the manual). At first sight it makes your builds very easy but there are of course downsides.

What’s great about the bundle (first sight)?

  • It includes pretty much everything you’ll need. PDB with current sensor + VTX with OSD and of course the FC Colibri Race 2.0.
  • It is very nicely designed with a very flat form factor of 1.45cm height (the top of the white connectors). It nicely fits into the ImpulseRC Alien 5″ frame.
  • You can integrate Crossfire easily and get a very compact long range system which can be configured over OSD (PIDs, VTX, camera).

What’s NOT great (first sight)?

  • The ESC extension board is placed pretty high in the tower so the ESC wires have to be placed high in the air which will cause trouble while flying. The chance of hanging on trees with wires soldered that high are pretty damn high. You can’t decide to move components up and down. So you can’t move the ESC board to the bottom. The ESC board has to be soldered to the FC.
  • TBS used MPU6500 gyro, which is known to be rather noisy when compared to MPU6000. This may cause trouble when tuning the kwad.
  • The price seems very high. USD130 is too much for FC (normally ~USD30), OSD (normally ~CHF5), PDB (normally ~CHF10) and VTX (normally ~USD35) and the components normally cost about USD80 all together. I think USD100 would be a great deal for the bundle.
  • I don’t get why TBS is including that strange/uncommon SMA connector. For my ImpulseRC Alien build (and pretty much every other build) I will need standard right angled SMA or RP-SMA connector.
  • I have no idea whether the UFL connector on the VTX will hold. It popped out in my hands and I did not even pull on it. I suggest to use a bit of hot glue to secure it.

Now it’s about to wait for the other kwad components to arrive.
