Thats the exact one, its a "wild wheels heli"
I was told i was getting a sky shadow, but i got that instead :\
Im guessing there all the same though...
When you say either one side or the other has too much pitch, do you mean the actual tail rotor, or do you mean the problem is with the two main rotors?
Im having trouble understanding what you mean by balancing the rotor on a metal knife

.
I was considering taping a small piece of wood or bamboo to the boom to absorbe some of the vibrations.
Any further info would be great
And thanks for your reply mrasmm, i was about to give up on it...
