Mobigital7 75mm Digi Whoop - Naked DJI O3 Air Unit

Decided to jump back in to whoops for the rainy Portland winter. I built a TP3 with naked vista and flew that a lot last year so was hoping to experiment with a similar setup on a whoop frame. As I was digging around, I came across Dax Neal and the Mobigital7 Owners Facebook group, https://www.facebook.com/groups/338543201686850/ . Dax had just posted some pics of a decased DJI 03 Air Unit on a HappyModel Mobula7 75mm frame and had some amazing video using 1102/10,000kv motors on 1s. I was hooked and decided to give it a go. Dax produced some great build videos and is very engaged in the FB group.

I've decased a many vista units however the new 03 air unit was a bit more challenging and too a little longer. The overall build it pretty straightforward with the execption of connecting the motors. When using the Mobula7 frame, you have to solder your connections by threading your motor leads through the frame. The motors themselves are too big to fit through the plastic holes on the frame so you are not able solder up the motors on the bench and then tranfer the FC and motors to frame. Maybe there's an easier solution however I found it to be a bit challenging to find the right postion for the frame and still have easy access with the iron. With inspiration from Dax, I also 'threaded' the battery leads through two small frame holes after the board and motors were mounted on the frame.

The DJI 03 air unit boards sit on a number of custom designed spacers between a structure of M2.5x25 nylon screws. Dax created a few other printed parts that seperate the board and hold the 'decased' camera. The DJI 03 Air unit has a pretty long camera connecting wire and because it's new, we haven't a reall short wire that would eliminate the wire coal on top. It's fine for now but will be replaced with a shorter cable and clean up the overall asthetic. It will aslo likely pull off another .5 grams.

Overall, a fun but challening build! Love how it flys and already thinking about building another. Dax Neal also has a site called Quadsensei https://www.quadsensei.com/mobigital-7 where he sells the printed parts and some of the components mentioned above. He aslo builds to order so that's a nice option for someone new. I've included a bunch of build pics below but hit me up if you have any questions. Happy to help!
