Hehehehe......as cool as jumping to the Optic 6 will be.....

I wouldn't jump to conclusions though, but that IS weird. It seems like your servos still work though, so nothing wrong there. I don't want to think that the 4-in-1 is shot, because sit'd have to be pretty rare for it to suddenly get its CCPM mixing all screwy. Double-check your transmitter to see if the reversing is all set right. Then disconnect the servos from the swashplate and see individually how each one moves. All three servos should have their servo arms on the upper half of the case when they are mounted on the heli. Look back on how each servo should move, there's gotta be something wrong with the way they're plugged in now. I seriously doubt that the 4-in-1 is screwed up, because if it were you should be getting no response in one or more channels, not screwed up mixing.
