Built myself a Micro brushless this weekend:
Racerstar 1103 10000kv motors
Racerstar 2035 props
Racerstar 4in1 6A ESC
Pico BLX clone
Realacc Bobo 95 frame (BG)
2S 350mah mylipo
Weight around 45 grams without battery
With battery: 65 grams
First impressions of a quick stormy maiden yesterday: Pretty good, needs some tuning, not as much power as my 4S build but the fact that I'm even comparing it to that says enough. It's easy to forget you are flying a tinywhoop sized quad. Got around 3 minutes of flight time coming down at 3.7 volts. Beeper screaming critical voltage at that time so it needs some adjustments.
Had some trouble with the build, apart from it being very tiny: first, the 4in1 ESC I received was faulty, 2 motors were twitching and didn't spin. Luckily I had another one, replaced it and it worked fine so I'm gonna test out Banggood's support for the first time, hope I get a replacement.
Second problem: The 4in1 install was confusing, couldn't find any info anywhere how to set it up so I had to think myself. It has power leads so I figured I would connect the battery to that and run the FC off the 5v output. This worked, however the FC could then not read the battery voltage (duh). Apart from that, all worked fine until I turned on the power of the TX03 to 200mw. Things started to crap out, vtx channel constantly changing and not responding anymore, some motors spinning up randomly. Turns out running the FC + receiver + 200mw vtx off the 5V output of the 4in1 is not a good idea.
So I had to fully disassemble it again, and ran 2 seperate wires from 4in1 battery connection to the FC voltage input, and it's working great now. Lesson learned.
