Just an update. I spoke to Evan at Tech Support, and Horizon is willing to replace the Pizzazz for free, and they are going to sell me a new Saito 72 at a discounted rate. I asked if they had any rebuilt or reconditioned engines. He said they would check and let me know tomorrow. They are also going to check out my radio setup as well. I was hoping for them to replace the engine on the cuff, but he pointed out that some of the wing failures are caused by cutting too deep into the wing sheeting before you glue the wing in place.
