I've really enjoyed the Mobigital7 75mm 03 Air whoop that I built a few weeks ago! It's still amazing to me that you can have this kind of video performance in such a small build. The naked O3 Air turned out to be roughly 46g depending on props and I knew from building many naked Vista's that I could take the weight down and improve freestyle performance. Don't get me wrong, I think the original 1102/10,000kv motors on the first one are the sweet spot but wanted to experiment with something lighter.

I used the same recipe used on my first one HERE. Same frame, FC, and build details. This includes drilling out a Happymodel Moblite7 Mobula7 V3 Frame and then running four M2.5x25 nylon screws from the bottom to support the FC and Vista boards. It's a proven method that Dax Neal introduced on the orginal Mobigital7. He's got a great FB group HERE and even a website catering to parts if someone needs help printing or decasing the DJI units. He also does a BNF build for beginners or those who are not ready to build. Good dude who is active in the community and always testing out cool new things.

The key difference on this build was the selection of 1002/14,000KV motors. These motors are measurably lighter than than the 1102's and paired with the lighter Vista and Nebula Pro Nano it allowed me to shave off 8 grams! I landed on 38 grams dry. Surprised myself a little that it came in so light. The only real tricky part of this build was soldering the motors through the frame. These bigger motors don't fit through the frame like 802's so you have to pull the wires through and find a way to solder. The pictures below show the balancing act!

You can really feel difference in handling however you're giving up a bit in video quality. I still personally love the vista so that's no biggie to me.

Check it out. Lots of build pics and happy to answer any questions.
