The plane I purchased had a defective engine cowl. I was referred to the manufacturer for replacement. Manufacturer sent me another cowl but because they didn't state it was a warranty replacement, I was responsible for paying the dues owed though FEDEX. Manufacturer would not return any of my emails that I sent to them letting them know what happened so they could correct this. I informed Tower Hobbies of what was going on, they refunded me 50% of the cost of the plane! What an amazing gesture! More than what I was expecting!
