I think I might build one of the lightest setup in Bi-copter drone family. The copter without battery weights only 105 grams. I will develop it further with ArduPilot code and additional sensors like Lidar and Flow control. Here is the video of one of the flights where I wanted to see what is the biggest battery that it can carry. https://www.youtube.com/watch?v=0WlvRYLKgRQ If anyone got questions or suggestions feel free to reply under this topic.

Looks really good!
I really like the idea of making a micro drone as it’s less prone to damage during a crash and can fly indoors.
Just curious how it handles Oscillation during backwards flight as Bicopters are known to have this problem?6 December, 2018 at 17:15 #60438
Forward or backward flight is smooth without any problems. Only in hover he got a little servo shake but I quess its cause of its really small inertia that he can not stay quietly in one place qnd everything makes him goes out of balance but it is not that much a problem. You can watch Youtube video and see by yourself that while moving he goes smoothly.6 December, 2018 at 18:13 #60439
Yeah i saw the video. However the flight was pretty much just hovering around a lab space. That oversized battery does give the copter added stability. Using a smaller battery you’d see more oscillations and instability.
What I’m talking about requires some speed. Bicopters often have issues turning sharpy while in forward flight. (Nose drops causing the copter to flip) Or oscillate wildly in reverse flight past a certain speed as it runs through its own turbulance.
Look at Davids, Bicopter video for details.7 December, 2018 at 12:37 #60461
I dont have such problem. I didnt go very fast since I only flew in hangar but from what I saw so far the faster it goes more stable it becomes.7 December, 2018 at 13:00 #60472
Video or it didnt happen.14 December, 2018 at 08:18 #60548
https://youtu.be/la9zBPI3nV4 Here it is. By the sound it can be heard that oscilations are getting much lower as he gain speed.14 December, 2018 at 08:19 #60549
https://youtu.be/UhhceKiv_i0 Current balance. Still need some cosmetic PID change.14 December, 2018 at 13:49 #60551
The last video looked really good. I’m sure those ducts helped a bit with stability too.15 December, 2018 at 14:26 #60567
I am actualy going to do some whooping with it with FPV camera. Maybe its gonna to be actually the first bi-whoop. (With small 3S battery I can go to 150-160 gram totally so not rly a tuny whoop but kinda still a whoop 😀15 December, 2018 at 14:28 #60568
You had previously mentioned Lidar and flow-control, have these been added? What specific advantage would either bring to such a small copter?19 December, 2018 at 12:28 #60600
I desing and develop small inspection drones. Bi copter was built more to learn and study about this configuration with keeping in mind building VTOL aeroplane. But since it flies so nice now maybe I will think about putting some sensors on him also to make perfectly stable and easy to control in narrow areas.
