Of-course it's used, came from disassembly of some science equipment in Israel. The only issue was 1 bend pin on a pump, which was probably not used.

FLYING FPV - BETA85X It took me 3 years of sparse attempts to start flying FPV. Finally it looks like I got it. At some point my brain rewired RC controls to helicopter flying experience in Battlefield 3 and it all snapped into place. What finally pushed it over the edge was reducing rates, enabling AIR mode permanently and getting 5 batteries (on such tiny quadcopters each battery lasts only ~3 minutes). I compiled some of the first FPV flight attempts on Beta85x with some after 30 minutes of flight time: PS. This is my second FPV quadcopter. I was flying first one (ARRIS C250 V2) visually mostly, and it was completely wrecked beyond repair in less than 20 minutes of flight time. It makes this hobby the most expensive one, if you calculate per hour expensesJuly 5, 2019

DUCKS DO FLY!
In urban Russia we used to see ducks and swans not able to fly due to their trimmed feathers. Or maybe after generations of not flying there is no one to teach them fly? I wonder if a bird can learn to fly if it's parents never flown... Here in Italy - ducks and swans do fly. But people say several years ago there were much more swans, probably they have flown away... Freedom comes with a price tag. One can see these ducks learned a lot: how they increase angle of attack at landing to reduce landing speed, how they can land with or without thrust reversal (if they feel it's safe), how they neatly tuck in flippers in flight to reduce drag (reminds me of Boeing 737 landing gear)... They even have sharklets!Read more →
