I have to tell you I had two WH Extra 330L's, 140 size and both of them fell apart in the sky. They were built with all dubro hardware and radio south hinges and they both crashed after two or three flights. The first one actually started to lose the covering on the right wing after the first flight. The second one lost one elevator half but i was able to save it. After repairing the elevator using extra RS hinges, it failed again causing it to slam the ground. I think they use inferior wood and covering. Maybe others have had better luck but I'll never buy another one.
