thanks for the pics
the weights on the rotors are to give the main rotor a little more stability. it takes more power to overcome the gyroscopic forces of the weights at the end, which would help keep the entire heli more stable. the gyro looks interesting. i assume the tail motor is geared to that flywheel and the flywheel is weighted? that would basically create a simple mechanical gyroscope that would act against the left and right rotation of the tail (like trying to turn a spinning bike tire).
i noticed the same right side lean on the PicooZ, i think its built into the frame so that the heli is leaning away from the way the heli wants to tip when it first lifts off and is in ground effect. they did some serious thinking on these little helis! did the heli not fly outside because it would lose the signal, or was it something else? if it kept losing signal, its probably interferance from the sun. are you using your own charger to charge it?
i cant wait to get one of these
