Quadtonomous rotor 4 U


Now some test flights of 200Hz PWM. 200Hz PWM changed everything.

The stability with 200Hz PWM is freakish. Holy mother of molasses it's stable. It's like flying the Corona again. Full manual mode has returned. With that, the quad rotor was open 4 business.

Sideways lunges went away. Either it was the damping or binding in a motor. The starboard motor seems 2 have a damaged bearing. Got some more life out of it by lubricating it.

The quad did its first reasonable autonomous hover. Take a look at the Goog replay.

Quad rotor's first autonomous hover. (1 min 5 sec)


The hover was 170sec & condensed to 64sec 4 U home gamers. For the first 70sec, we had to command a 2m/s climb rate. Altitude hold doesn't work very well. 170sec was the limit of the battery.

Flight times R still real short. Even if it's balanced, the batteries get flaming hot within 3 minutes. Need better propellers before trying anything longer.
