Today I bring you the first build for our website. This days we search for light quads but at the same time powerfull enough to enjoy our free time. After several 5″ quads builded, I though that I could get enough fun with a tiny quad, so I decided to build the first 2″ quad. With a lack of experience with this tiny quads I searched on internet isolated parts always with the intencion to collect a good combo. I started to pick up some of the parts that I selected and started to build the quad. I already flew it and at the end I’ll show you the result, but first I’ll let you know the choices I’ve made and will let you know more about them.
Like I said before I had to choose the parts that suits me better, so because I wanted a 2″ quad I started to choose the frame and the choice fell on the Flynoceros Cerberus Micro, after I needed to get some good motors for the baby quad, so I picked up the iFlight iPower iX1106, for the FC I choosed the OMNIBUS AIO F3 Nano, for the ESCs I picked the Airbot Ori32 4in1 and then for FPV systems I choosed the RunCam Micro Swift 2 and the VTX03. I picked several props, but the best for this setup were the Gemfan Hulkie 2040.
- Flynoceros Cerberus Micro;
- iFlight iPower iX1106 7500kV;
- OMNIBUS AIO F3 Nano;
- Airbot Ori32 4in1 4x25A;
- RunCam Micro Swift 2;
- Gemfan Hulkie 2040;
The frame made by Flynoceros can fit up to 2″ props and is named Cerberus Micro. It’s a 3K carbon fiber frame with 119mm motor to motor and a base plate with 2,5mm thick. Featuring a unibody frame with roll-cage that is secured to the base plate only by one screw the all frame feel very rigid and very reliable. The frame type is a stretched X that turn this quad very agile. Into this frame you can mount motors with 11XX size.
To spin the props on this build I picked the iFlight iPower 1106 7500kV, really tiny motors but also powerfull enought, weighting 5.5g and with a voltage range between 2S and 3S LiPo battery, turned this motors a great choice for this build. Before mounting them on the quad, I tested them on a thrust stand getting the following results:
Because all quads need a flight controller the choice for this drone was the OMNIBUS AIO F3 Nano, on a 20mmx20mm mounting holes board it features an F3 ARM processor, the old but reliable MPU6000, as also barometer BMP280, current sensor that measure up to 60A, OSD built in and is also a PDB. The OSD and the gyro are connected to the processor by SPI protocol. Because it’s is a reliable FC it becomed to be a great choice for the build.
Warning: This FC can take only up to 2S due to the voltage regulator.
To drive the motors I searched for the best and tiny ESCs, the choice was the Ori32 4in1 4x25A, they have 20mmx20mm mounting holes and with the latest BLHELI firmware flashed, made them a serious competition to the other ESCs on the market. They have current sensors for each ESC but not the RGB LED. This board is of course also a PDB and for this build I needed another PDB besides the FC choosed, because I wanted to power the quad with a 3S Lipo and the FC only allow up to 2S, so I connected the battery lead to the Ori32 ESC board and with the voltage regulator on this board I powered the FC with 5V. On the build matter I have to say that the motor layout on this board is not the best, so I had to cross the wires from two motors to be able to solder on the correct place. On other hand this ESCs work flawless and provide the motors with all the current they need.
The FPV camera choosed was the Runcam Micro Swift 2 perfect match with this frame and sending the video through the VTX03 a 72CH VTX with switchable power between 0 and 200mW.
At the beggining I though that the build process would be really quickly, but I was wrong because everything is so tight and the room to fit everything is so small I took the same or more time like if I was building a 5″ quad. Of course all the building process is a really amusement, I think every pilot like to build it’s own quad. Like I said before I had to power the FC with the ESCs board, so the best way I found was to connect both with the SH1.0 cable, I get a really short one that helped a lot with the space occupied. With this tiny frame and with a two layer stack the space available to fit the VTX and receiver were really narrow, so I bought a really small radio receiver (Flysky A8S v2) besides it’s not a diversity receiver it allow me to have a great range. The antenna that come with the VTX is also pretty small and again helped a lot the build process.I made a time lapse video of the build, hope you enjoy it.
The final result is 100g of pure POWER!!! I think it’s a bit heavy for this high kV motors but it looks really nice.
I recorded a flight DVR that you can see below. For this setup I get a quad plenty of power, every punch on the throttle make the quad “disappear” in the air. It’s a really fast quad, but also a battery consumer, this motors asking for almost 14A each, is too much for a small LiPo. To test the quad I bought two Infinity 550mAh 3S 70C, after some flights and having almost 2 minuts per flight on “cruising mode” I reach the conclusion that maybe if I go for a 450mAh battery which is a bit lighter maybe I can get more flight time.
PS: The current and power showed on the OSD is not real because the current sensor from the ESCs are not plugged to the flight controller.
Flying this quad is a really joy, it’s really responsive and plenty of power. The frame is rock solid, has a complete roll cage introducing a great stiffness to the all frame. The FPV camera is protected by the roll cage. The frame is also a light weight one. On the motors matter I needed a long wires, I think that more 40mm should fit every build, also the motor bell should be better glued to the shaft. Until now the motors handled very well the 3S LiPo and each one can provide almost 70g of thrust at 50% throttle, so on a 150g quad with battery the 4 motors provide 280g of thrust, more than the quad weigh.
The ESCs choosed turned to be a great choice, and I have to say that I’m really impressed with the product quality that Airbot introduced on their products. The PCB boards that Airbot is using on their products are really good.
I have to try the quad with another battery sizes because I feel that the quad is a bit heavy so maybe choosing smaller batteries could be a good solutions.
I want to thank to Flynoceros, iFlight and Airbot for the opportunity to test this products.
