Lighter Twig

Is there something between a toothpick and a twig? A 'piece of scraggle'?

I was looking to build something light and cheap to fly around the driveway or (outdoor/open) parking lot at work. I had picked up the Eachine Twig 115HD last fall and wasn't really happy with the jello-tastic HD footage so I decided to use the motors, frame, canopy and the AIO board. To keep the weight down I didn't add a separate receiver but instead used the built-in SPI receiver on the CrazyBee board. I also used the Eachine Camera + VTX combo to keep the weight down and this fits perfectly in the Twig 115 canopy!

Added some HQ 65mm props and viola!

The SPI receiver actually performs much better than I thought it would - you're not going to be flying behind buildings but in an outdoor/open parking lot it's fine.

The AUW is 54g and 81g with a 2S 450mAH lipo. A 2S 300mAH lipo would probably be even better (lighter) but I don't have one lying around. You can fly it on 3S but I felt the extra weight wasn't worth it, your mileage may vary.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
