Hi!
I've built micro quadcopter 10 months ago for the purpose of learning acro mode (source: https://oscarliang.com/build-fpv-micro-q...lest-quad/ )
Oscar's blog helped a lot and I was able to make it fly but with FPV equipment micro quad flight time was less than 30 sec.
Then I have decided to take off FPV equipment but even then I could fly only for less than a minute which was quite disappointing. Quadcopter feels sluggish and lacking power.
I was trying to troubleshoot further, tested different battery types (Turnigy 300 mAh, CX-30 500mAh) but the results were not so good.
After that I have dropped CJMCU project until few days back.
As I'm very stubborn person I decided to read and learn as much as I can and tried to make it fly
What I have done so far:
- changed FET's on CJMCU - no difference in flight time
- added step-up voltage converter to power up RX to fix the issue with VD5M losing radio signal due to voltage drop below 3V
Total weight of the build:
- 27,9 g without battery
I would appreciate any suggestions and ideas how to improve flight performance of this tiny CJMCU board
