Corrections… When I mentioned “mAH” I meant “MW” in reference to the LEDs. Also the explanation of the power filter is probably slightly off, please let me know if there is a better way of explaining it! Also, if you are installing the OSD make sure to flash it ahead of time before installing, also you’ll need to use the included cable with this kit to connect the 5v, Ground, TX, and RX pins on the PDB to the Flight Controller.

Special thanks to the Brian’s over at Multirotor Mania- they’ve been patient with this build video which was supposed to be released over a month ago. Had some technical difficulties with production and the build, plus medical issues- am happy that it’s finally out! Am pretty happy with the result 😀

Also special shout out to Lance for the new lighting, and audio equipment donation from old friends the Motorcycles & Misfits podcast. Think I’ve figured out how to record these videos in a more fluid way in the future, look forward to improved production quality!
