If he is that dissapointed, contact horizon and see if they will replace it. I have heard of these issues with other H9 planes and horizon replaced them. I have heard that their customer service is really quite good. On a side note, I think its a good idea to inspect the entire plane when you get it to make sure the glue joints are solid. I added some extra epoxy to my P-47 im building as a precaution. Nothing wrong with playing it safe. Its possible that they got a bad batch of wood for the spar. It happens. All my planes are H9 and im pleased with their quality. Contact Horizon before you let it upset you too bad and see if they will take care of the problem. Good customer service can change your outlook on a company in a big hurry.
