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.

nice build! I did it the exact same with the screws to hold the entire stack. just a metal one that holds the cam. I believe it was Nick Burns that did it this way opposed to Dax who drilled them out.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Hi, nice one and thanks for sharing.
What lipo are you using with it ? Is it agile ? how durable is it ? Thanks
Thanks! I'm using Tattu 2s 450mah lipos and get 3 minute flight times. It's set up as a house cruiser at the moment however it can be super nimble outside as well. No problem with any of the regular flips, split s, etc. And it's super durable because its so light weight.
Thanks a lot. I've got a mobula7 1s elrs with the X12 aio . Now that I have DJI goggles I'll definitly put some research on how to convert it to HD. Frame is mobula7 v4, do you think I still can built something with it ?
You would have to modify the battery holder on that frame as the DJI system needs a minimum of 2s. I would personally buy a new frame that already allows 2s lipos. The FC that you have should work perfect. Hit me up if you need help
