Hi I had to change my main shaft and blades after a crash and now my rex is handling very sloppy.Someone at field told me maybe I need to change my settings because I changed the main shift.could this be my problem.
thanks Fred

Did you change the spindle?

No, changing the main shaft wont effect the handling unless its longer or shorter than the original and that threw your pitch off somehow.

Hi,just fixed it,the swash plate was off so I realined the control horns and now it,s good.Must of put the horns on wrong when I chaned the servo.
thanks Fred
