I just want to say that Horizon Hobby cares.
My Cr kit had some screws with malformed threads which also destroyed a nut until i realised the problem.
To make a long story short:
I mailed Horizon and they sent me the missing parts (From the United States to Germany!) for free.
BTW:
I've bought the kit via eBay and I get the service I only could dream about at the LHS.
