Feda Dragonfly Low RPM Vibration
Helli everyone,
My Feda flies real well, but sometime the heli vibrates violently when I attempted to decent about 1 foot off the ground. I took off again and the probelm went away. It happened randomly, so I cannot repeat the symptom at every fly. I had carefully balanced the fly bar, main blade, tied, and loosen the screws that hold the main blade, but it still happened some time. I am an electrical guy and not mechanical, so the vibration is still existing. Please give me your expert knowledge. Many thanks.

RE: Feda Dragonfly Low RPM Vibration
Try to add the weight on fly bar(balanced both sides) such as brass collar this keep stability and RPM not change so sudden. Low rpm with high pitch cause vibration.
