Forget my videos, watch this guy.
Building new quads started early this year.
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.
This is most probably the one and only killer combo for the micro FPV quads out there. The flight controller is not even officially out but I already have it and will start building my beautiful Eclair (yes, I give my drones names) seconds after posting the following pictures of the combo.
So the features for a freaking micro drone will be insane with this setup.
Airbot OMNIBUS F4 Nano V4
- STM32 F405 MCU
- MPU6000 gyro connected via SPI
- Betaflight OSD
- LC Filter
- 20x20mm M3 mount holes
Ori32 4in1 25A ESCs
- 32bit ESC with BLHeli32 (DSHOT1200 available)
- Supports 2-4S
- Voltage Output (VBAT)
- 20x20mm M3 mount holes
Everything I can say now is that the soldering pads on both boards are huge. Every casual solderer should be able to solder wires to them. The build quality of the boards is extremely good, as always for all Airbot products.
Motor Resource Re-Mapping
At first I though one of the ESCs on the Ori32 4in1 board is broken because motor 2 was not spinning at all. It was not so please keep reading.
If using the all-in-one connector to connect the OMNIBUS Nano FC and the Ori32 4in1 ESCs you most probably have to re-map your motors because the last pin of the white connector on the FC is actually motor 6 and not 4. That’s why after connecting you get ESC number 4 connected to motor 6 pin on the FC. Additionally if you rotate the ESC board you have to adjust resources accordingly.
A word of warning about the stand-offs. I had to get the nylon stand-offs down to avoid pushing components like FETs or capacitors off the boards while screwing the stand-off down. Please take a look before using your gorilla strength 😉
Today I was finally able to fly my micro build with the TomoQuads Sonic 2″ frame.
The build is documented @ https://www.aerosurfer.ch/2017/11/05/tomoquads-sonic.
For a very long time I wanted to fly something small, around 2″. It would allow me to fly near home and abuse local play grounds. I almost purchased the well known Eachine Lizard95 because friends of mine fly it and they seem to have tons of fun. There are millions of reviews of the Lizard saying that it’s a great (and lightning fast) quad but there are things that I don’t like about it, like for example the not so great FPV cam. Long story short I decided to build something myself and use premium parts like the Runcam Micro Swift V2.
The following parts were used in the build.
- Frame: TomoQuads Sonic 2″
- Camera: Runcam Micro Swift V2
- VTX: Eachine VTX03 Super Mini
- Receiver: FrSky R-XSR (featuring diversity + telemetry)
- Motors: SunnySky R1104 7500KV
- FC + ESCs Tower: XJB F425 Flytower Micro (featuring DSHOT600 + OSD)
- Propellers: Gemfan 2035 2X3.5X4
The quad is extremely fast on 3S batteries, using 2S would probably be enough as well as 5500KV motors.
