I have the same problem, I check my main rotor blades and make sure the battery is well charged. That usually solves the problem ;o)

Check your ballance on your main rotors as well. Sometimes vibrations caused toward the front can be seen mostly in the tail. Make sure ALL your equipment is SOLID. Also, check your flybar paddles to see, one that they are level, two that they are the same distance from the rotor head.
