ImpulseRC Micro Apex 3" for DJI O3 Air Unit

After finishing the build using a TPU print to have the camera outside of the frame for more space, I have edited the build to bring the camera inside the frame. Because of the 20mm width of the camera, I had to use another TPU print with 35mm long M2 screws in place of the stock standoffs.

Very cool design with the various antenna layout. How does the GPS location work with it being further from the VTX antenna? Do you get GPS lock fairly quick with the VTX powered up or do you have to power up just the GPS to get a lock initially before flying?

The GPS performs great wherever I've had it... especially the newer G10s.

Sweet! I'm about halfway through my Apex micro build and the GPS and VTX antenna are the last things I need to nail down. Do you still have the 3d files for the vtx antenn and gps mount variations on this build?

I do still have them. Give me your email and I'll send you everything I have for the APEX 3".

hey man, nice build! Any chance you can share that updated 03 camera mount? I'm using one made by my buddy but it looks like yours has more cam protection by placing it further back. I would like to try yours if you dont mind.

So here's the thing with this file... I found it on Thingiverse but it was made the the 5" Apex which is a little taller. I altered the file in Fusion 360 to the correct size. You're going to need 35mm M2 screws to run through the top of the frame, through the TPU prints and out the bottom. I used M2 locknuts on the bottom. It's a super tight fit but as you can see it definitely works. Good luck! Let me know if you have any issue downloading.

Appreciate that!

what’s that little TPU thing for mounting the 03 camera? does impulse sell that? I’m building the 4" version, and assumed 03 AU wouldn’t be an option

A friend made the O3 camera mount for me for the Kopis frame. It worked perfectly for the Micro Apex 3"! Here is the link...
