I have a Honey Bee King 3 and I am having a trottle problem. Sometimes the trottle works fine and the heli will trottle up to full speed and sometimes I can trottle halfway and the blades won't spin at all until I pass halfway and the heli wont lift. The battery is fully charged and Esky told me to change the ESC and I did and that did not help. Does anybody have any idea of what the problem might be? Thanks.
