This micro quadcopter kit from Canadaquadcopters.ca includes a light weight carbon fibre frame, a Lulfro brushed board, a set of CL-0820 motors and accessories. We previously reviewed some other kits from various vendors that don’t come with frames, and it is inconvenient for people without a 3D printer.
Get your Micro Quad Kit from CanadaQuadcopters.ca.
I would like to give a shout out to CanadaQuadcopters.ca. The owner Chris, just opened the store a couple of months ago and currently specialized in micro multirotor parts. They are based in Toronto.
Normally when we are trying to source parts for micro quadcopter, we would have to shop everywhere globally for the bits and pieces. I really appreciate Chris’s efforts to enable hobbyists to get everything they need from just 1 place. Soon they will also carry micro FPV setup so make sure you check back at their store later.
Chris is a really nice guy to talk to, if you have any questions about his products just get in touch with him!
Update (22/09/2016) – We have received multiple comments regarding the shop CandandaQuadcopter.ca not responding to emails and telephone calls, neither fulfilling the orders. If you wish to order from them, it’s advised to contact them first to make sure they are still open for business.
What’s in the Micro Quad Kit
Back to the subject, this Micro Quadcopter kit includes
- 1 x Carbon Fibre Micro Quadcopter frame
- 1 x Lulfro 32bit flight controller from Brotronics
- 4 x CL-0820-17 “Dark Edition – Insane Speed” Brushed Motors from Micro Motor Warehouse – 8.5x20mm
- 1 x Set of Hubsan X4 Propellers
- 1 x Nano-tech 300mAh 1S 45~90C Lipo
- Accessories, such as Strips of mounting tape to dampen motor vibration
I use the same battery in my micro quads, they are pretty decent. I get mine from Hobbyking and they all have reverse polarity. This issue has been fixed in the one that came with the kit.
Carbon Fibre Frame
3D printed frames are affordable and reasonably lightweight, but they also can be fragile and tend to bend after a few crashes. They also lack rigidity although it’s not generally a huge problem given the light weight of the quad. Overall 3D printed frames are great for indoor relax flying and cheap enough to replace.
However I would recommend a carbon fibre frame for your micro quad, if you fancy some fast flying outdoor without worrying about breaking it. Carbon fibre is also more rigid and lighter which is the ideal material even for micro multicopters.
CanadaQuadcopters.ca offers 2 types of 110 size frames, one is the Micro H Quad frame (left) and the other is the Racing edition frame (right).
The Micro-H Frame is a bit bulkier, and appears to be really tough. I love the rubber motor mounts, which just makes building so much quicker and easier.
The Racing frame is light as feather, but it’s a bit tricky when it comes to mounting motors. Here is how I did it and it took a while for me to get it.Here is how Chris does it in his video.
In the end I chose to build the Racing frame because I prefer a lighter setup which is only 6g (every gram makes a difference in micro quad!). You can tell the frame designers have tried their hardest to shave as much weight as possible on the frame
However because of that, I feel like there isn’t enough carbon fibre in the middle of the bottom plate to support the flight controller, It’s easy to have the FC tilted one-sided if it’s not mounted properly. If you are also building this frame, be aware that you might have trouble accessing the serial pins on the Lulfro board after you put the top plate on.
My work around was to bend the pins, so I can still plug my cables in through the gaps and from the sides.
But anyway, this quad is lightweight! Excluding battery and FPV gear it’s only 32 grams! This is 10 grams lighter (20%) than my previous build using a 3D printed frame.
Lulfro flight controller brushed board (Brotronics)
Same as the Beef Board, the Lulfro is a 32-bit FC with integrated FETs (ESC). It comes with Baseflight pre-flashed, but you can also flash Cleanflight and even Betaflight on it with the Naze32 firmware..
For setting up, there is no official documetation, but Chris has kindly put together a manual and it can be found in the Lulfro product page. Setting up is extremely similar to the Beef board if you have experience with it, this board is a piece of cake.
By the way in the documentation, one of the picture suggest you need to short the bootloader pins to flash Cleanflight. I found that’s not necessary, I could flash without shorting those pins.
Dimension and Spec
This board is weights only 2.4g, dimension is 25mm x 25mm. FETs are rated 6.3A each compared to 4.2A on the Beef board. You should check out my comparison table of different Brushed boards.
Supports PPM, Spektrum and SBUS Receiver
The Lulfro board supports PPM and Spektrum/SBUS/SUMD receivers, and it’s capable of providing 3.3V and 5V power for your RX. So in theory you could use a D4R-II or X4R-SB on this board! (The frsky D4R-II weights only around 2.7g after stripping)
CanadaQuadcopters also carry Frsky Micro RX receiver that works with Taranis TX. Here is how I soldered mine.
Filtered 5V for your VTX!
The 5V pins next to the TX/RX becomes a 5V output when you connect the LiPo battery (Step up voltage regulator). You can use this filtered 5V output for your FPV gear if they support 5V as input. I am able to use Lulfro board with my FPV setup, no noise at all even at full throttle, so filtering is working great!
Requires FTDI cable
The board requires a CP2102 or FTDI cable to connect to the computer (ie. Cleanflight/Baseflight configurator), or flash firmware.
I used the cable from CanadaQuadcopters.ca, and it worked perfectly.
Installing FC on Frame
When you are putting FC on the frame, make sure you have the correct orientation. There is an arrow on the board and it should face forward. Here I am showing you a WRONG example. You can certainly rotate the board, and set yaw offset in Cleanflight, but make sure you are connecting the motor in the correct order.
MMW Dark Edition – Motor/Battery/Props Tests
These 8.5mm motors are allegedly more superior than the silver ones you normally get from Banggood or Hobbyking. (and more expensive!)
Last time I compared the batteries and props, but that was a bit subjective and I didn’t make any scientific tests. This time I used my digital scale to take some numbers so hopefully the results are a bit more convincing.
Basically I strapped the quad to some weight, and put it on a digital scale. Write down the initial weight, then apply full throttle to see how much weight it can reduce by lifting. The difference would be the total thrust generated. Final result is then divide by 4 to get thrust per motor.
*Lady Bird Props were from Hobbyking, Hubsan props were from CanadaQuadcopters, Rolling Spider props is made by Parrot.
Multirotor Superstore Motors
Motors were used in this build.
|300mah 45C||350mah 65C||600mah 35C||750mah 35C|
MMW Dark Edition Motors
|300mah 45C||350mah 65C||600mah 35C||750mah 35C|
The motors I got from Multirotor Superstore (MS) actually performed pretty close to the MMW Dark Edition. Also bear in mind that I have had more than 30 flights on the motors from MS already, so performance should be a bit better if they were new.
Note that these motors are not designed to be run at constant full speed. The thrust isn’t linear and always tails off as you increase throttle (just like any other motors really). I cannot guarantee this test was 100% accurate, because it was carried out on non-standard testing equipment. But that should give us some ideas how the motors react to different props and batteries.
Really Cheap FPV Setup
I used to connect this FPV setup to the main LiPo, but I found the power is too noise for it, so I gave up using it. Since both VTX and camera support 3.3V-5V, we can safely run it off the filtered 5V output on the Lulfro board.
But be aware that the Banggood camera is 170 degree lens, some people might find it too wide. Surveilzone has one with similar spec that does 120 degree, but it’s twice as expensive.
Also note that this setup works only on Boscam frequency Band E.
Check out how I built the low cost micro quad FPV setup.
Example how it would look like :) I will probably put the camera between the plates in future mod!
I will come back and update if I have any more discoveries or videos on this build.
