Holy Stone HS110D Drone PCB Wiring - What does the circled wire in the picture do?

That is almost certainly the antenna and one end is supposed to be free. This is increasingly likely as the square black chip next to it (labelled PAN159CY) is the wireless transciever (radio) - and I ...

Is it common to break ESCs?

Aside from quality control issues with the product, the only real way to destroy an ESC faster than the effects or normal wear and tear (minimal) is to mistreat it: Using it with a voltage higher ...

Is superglue (cyanoacrylate) a viable means to repair quadcopter frames?

Won't repeat two answers already given - offer this only as an addition to both. Might try placing a small piece of shrink wrap tubing around broken strut (before) super glue repair. After superglue ...

Is superglue (cyanoacrylate) a viable means to repair quadcopter frames?

some frames are carbon fiber and I wouldn't expect superglue to work well. CA is surprisingly good on carbon fibre. It wicks into the cracks and around the splinters, and the large surface area gives ...

Is superglue (cyanoacrylate) a viable means to repair quadcopter frames?

It depends on the risk you are willing to take, but for such a small drone being flown indoors I'd give it a go1 and accept it may crash - after all, it has already done so once so it can't be made ...

Can I salvage a 4in1 ESC?

You would have to be careful so as not to lose some functionality like current sensing or affect the CG of your quadcopter. One way I could see this working is leaving the 4-in-1 ESC on the stack in ...

How to straighten a motor shaft?

I found this interesting method that can work for larger motor shafts. It involves putting the motor shaft into a drill to spin it. Then something longer is attached to the other side so that it can ...

Is it common to break ESCs?

ESCs usually last for ages. I still use the ones I bought when brushless motors were relatively new, 15+ years ago. That said, if you buy the absolute cheapest they do occasionally just die for no ...

Drone back propellers not lifting it up

The most likely cause is that the propellers have been swapped. Drones have two types of propellers, for clockwise and anti-clockwise rotation. These must be fitted in diagonally-opposite pairs. If ...

Can I salvage a 4in1 ESC?

As ifconfig pointed out, the most common way to continue using a not entirely functional 4-in-1 is to solder a standalone ESC to substitute for the damaged one(s). Balance is not that much of an issue ...

Is it common to break ESCs?

Yes, ESCs are semi-disposable. I smoked 3 before I flew my first flight. I buy esc's in groups of 5 (same for motors - I fly quads) then I have a spare for failure. Been using that pattern for 5+ ...
