My little remote control UDI U818A quadcopter has provided a lot of fun over the last few weeks. I feel like I’m starting to get a bit of a handle on it. It no longer feels totally out of control. That said, I still have to be careful to keep it facing away from me as I can’t make the transition to reversing the controls when it is pointing at me.
Sadly, two of the motors stopped working recently. The front right and rear left motors both stopped at the exact same time. I thought sure this was an electronics problem. At the time, I wasn’t sure how to troubleshoot the problem. It later occurred to me that swapping the wires with the working motors would have probably worked.
I immediately ordered two new motor “arms” from Amazon. One has to be careful to order replacement parts (motors, propellers) that match the direction of rotation needed.
The replacement arms/motors showed up in two days – Amazon Prime is a wonderful thing!
Swapping the parts out was very easy but the screws are VERY small. In just a few minutes, I was back in the air. Yay!
