Swedish engineer takes DIY 'multicopter' for a test flight

STOCKHOLM, Sweden, July 22 (UPI) -- A Swedish engineer shared video of his successful test flight in a homemade "multicopter" powerful enough to lift him several feet off the ground.

Inventor Axel Borg posted a video to YouTube showing his test flight in the multicopter, which he has been building for more than a year and documenting his progress on his amazingdiyprojects channel.

Borg says in the video that the copter remains difficult to turn, and turns faster to the right than the left.

"I suppose some of the motors are stronger than others," Borg says after his flight, "but great fun, anyway!"
