This is my first post, so forgive me if this subject has been addressed before, but I cannot find it. Received my empannage kit last week and finished he inventory a couple days ago. Good news, only one screw was missing. And they mailed me a new one in two days. The one thing I'm curious about is the condition of the four HS-902 front and HS-903 rear spar parts. All four have a very slight bow to them. The packaging had absolutely no damage whatsoever and all the long/thin parts were securely bundled together. Any advice? Is this normal, or should I contact Vans?
