I own the TREX and the way they say in the instructions is to mount the ball link on the leading edge side of the tail blades just like the instructions for the 3dpro ---but every one is saying this will help cause tail wag so they mount there's on the trailing edge side of the blade grip.
is this also true for the 3dpro? i have mine mounted on the trailing edge and i have no tail wag but the tail authority is very poor the piro rate is very poor almost like the tail is being held to hard from rotating. i have the gws gyro. the only way i can make it better is lower the gain down, even then she wont turn very fast. i am looking to replace it with the 401 but for now i would like to get it to work.
please any help with this would be great.
