You might want to try and figure out why the vanes are getting wavy. Is it a tuning issue? The vanes may be hitting the rest. As stated ina post use the hairdryer to fix but I would find out the reason first.

its them going to deep into my target

OH, OK

Another thing that can make ur vanes get wavy is when they go thrue the Whisker Buisket.

hair dryer works for me!
