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.

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..
Read moreWith the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! 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..
