I have a few WM arfs and all of them are covered in their chinese made covering, it is thin not very adhesive and has very low shrink value. I have emailed them on this at their website but no replies! Basically use it until you cant stand it then rip it off and use Ultrakote or Oracover to replace it, thats what i have done and taken the oportunity to add glue to places that look shy too. They do fly well as models and I have no problem with that, but they also fit silly little wheels too which are useless on grass.
