This has been a fantastic build. Stock tuned, it burned up a motor on the second day of flying. After that I tuned it up, added a Foxeer Box 2, and a GPS module.
I found that the full tower with the DJI air unit was a smidge too tall for the frame. The front and back screws create a spring fit against the stack.

On a later outing, the craft had a hard fall from four meters onto asphalt. It cracked the lower ring and shattered one of the duct liners. If I manage to break it again, I'll 3D print the replacement. Fortunately replacement parts came quickly. Now it flies like a champ.
