I have set up my gt many times with wizard. On attempting take off with my Blade 330 it violently dives to the right just before lift off.
Swash is level. Servo horns are perpendicular to servo bodies.
Any suggestions?

I have Five Heli's set up with the GT FBL and Geolink. And all except this Blade 330 fly perfect.

This heli was flying great before a crash. And everything on the head was replaced

The Swash is perfect, the blades are 0 degrees at mid stick and tracking is also perfect.

But when I go to take off now, the Heli wants to do a hard Right tilt.

Need some suggestions on what's going on , Please

This problem could happen if:
a) Mounting Position is selected incorrectly - gyro compensation is wrong.
b) Swashplate Type is selected incorrectly - gyro compensation is wrong.
c) CH1/CH3 servos are swapped or reversed incorrectly - gyro compensation is wrong.
d) Collective Pitch reverse is not ticked - gyro compensation is wrong. This is required for some Blade helicopters since rotor head is designed differently than the most other models.
e) There are extremely high vibrations coming from tail or motor - can be easily checked with Spectrum Analysis at Aileron axis.
