...back to Flying RC Vehicles overview

Because I did not really feel comfortable with the large size of both my first copter and my tricopter, I decided to build a very small and lightweight 1S brushed quadcopter. The frame is 3D printed, but because it did not fit my 3D printer at the time I had to order it online.

Here are some recordings of the FPV footage. Be aware that these videos are recorded from the received signal on the ground. Not only can you see lots of interference and other HF problems, the loss of quality from the video recorder and the YouTube encoding is also very noticeable. In real-life, the picture doesn't look that bad.

Brushed Copter Test Flight

As you can probably tell from the pictures, I was a bit scared about my first AIO cam with a soldered-on antenna. After I had to re-solder a new one once, I covered it in copious amounts of hotglue, to avoid crash damage. It seems to work.

To mount the battery to the frame I used a small piece of 3M Dual Lock on both the copter and all of my batteries.
