Just wondering but I finally crashed my trex450 and rebuilt it and now I can't get the blades to track right. Only thing I can figure out is the main shaft is bent or the blades I have are junk, the plastic one, probably need to buy wooden ones or carbon? Any ideas would help out a lot, been flying airplanes for years and heli's are a diffrent breed.

I doubt a bent main shaft would cause blades to go out of track, usually would just have bad vibration. However, it could be the feathering shaft, and you should generally replace both shafts after every crash.

And yes, plastic blades are junk. Woodies are ok, but the Align white carbons are awesome and tracking is dead-nuts.

yup... a feathering shaft would do that.
Also, make sure you are only adjusting one blade or you will be going in circles... no pun intended.

Just go ahead and replace the feathering shaft they bend easy.
Replace you're O-rings or Dampeners, they can get misshapened or damaged, I use Trueblood Red Dampeners.
Swap you blades around to the opposite blade grips, if the same blade is high you have a bad blade.
Now adjust you're tracking if necessary.

Cool I noticed a lot of play in the blade grips, I guess from the dampners, anyways had a xtra head setup from another trex, swaped them out and it flys again. Thanks for all the help.

On the head that you replaced is it plastic? Some of the plastic parts can develop slop after a crash, yet not be busted. I had a plastic see-saw holder develop slop after a crash. There was no visable damage. The plastic had just elongated a little where it screwed in, thus producing slop, and blades that would not track. I replaced the offending plastic part and the blades tracked perfectly.

Beware of Plastic head parts.

Try snapping the endlink on the ball link of the blade grip backwards. (This will give the linkage half a turn instead of 1 full turn) Or you can take the ball link off and snap it on first then put the ball link back. Sometimes I have to do this.

You can always adjust some of the lower linkages to modify the tracking.

A good set of digital calipers is your best friend. I usually measure the center of the endlinks and the outter distances just to make everything match and all the endlinks are equal.
