hobbyking Oversky MUL A Flight Controller

Hobbyking is currently selling the Oversky MUL A Flight Controller at ridiculous low price. This FC has everyting onboard and is currently for sale at hobbyking for less then 5$. But is it worth buying this FC ano 2023? What can you expect from it and what can you do with it.

The specs of the board are very promising.

• CPU FC board : STM32103CBT6
• IMU FC board : MPU6050
• USB,OSD,DCDC power
• 5.8G analog VTX/500mw/32CH/cam supports FatShark goggles
• LED tail lights and Buzzer
• 7 channel DSMX compatible receiver
• Supports outside compass and sonar
• Supports Cleanflight and Baseflight firmware


This board has no MAG and no BARO sensor. This can be a problem if you want to use this board for autopilot missions. But for basic FPV flights these sensors are not needed.

So I bought the board and here is the verdict:
This FC board is worthless unless you are realy into DRONE DIY projects and have some soldering skills. So don't buy it if you need a PNP (plug and play) flight controller for your drone project.

And here is why:
- The FC board, which is NAZE32 compatible, is shipped with Cleanflight version 1.12. This version is outdated and you can't find a working PC software to configure it (ano 2023). You need to upgrade to a more recent version.
- The OSD chip which is minimosd compatible is shipped with MWOSD version 1.5. This version is outdated and you can't find a working PC software to configure it (ano 2023). You need to upgrade to a more recent version.
- The PDB has very small soldering pads to connect the ESC (motor controller). The manual states that brushless motor as from size 2203 are not suported. This is due to the current limition of the PDB caused by the small soldering pads. My guess is that even motors with size 1806 or even 1407 can demand to much current and can damage the soldering pads.

In the next BLOGS I'll provide more information on how to overcome these issues and update this FC so it can be used ano 2023. So after some tuning you will have a working AIO Flight controlle for less than 5$! Be quick before they are soled out.
