I personally dont recommend trying to straiten the shafts yourself, especially the outer shaft. You will never get it perfect. We have tried time and time again.....


The things that you need to check for after crashing are the fallowing..

first, the blades.
then check the flybar.
next check the shafts
then check the blade level, make sure they are perfect. You may need to adjust the flybar linkage to compensate and/or the servo linkages (rare) Your manual will show you how to check for this.
