I wanted something different with my silver carbon ZMR250, so I added a 10mm spacer and took the spacers from 37mm to 15mm.
The arms were moved as central as possible.
Did I mention it flies upside-down?

3D props are created symmetrically to give equal lift spinning in both directions, and software is set to allow the motors to switch direction so the copter can hover inverted.
I set up a three-position switch on my radio which changes the throttle range from positive range, full range, and negative range.
At full range, the top half of the throttle stick gives positive thrust and the bottom half gives negative thrust.

It takes awhile to get used to flying 3D!
I managed to successfully slam it into the ground trying to flip upside down testing line of sight. It's definitely easier flying FPV.

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
