Do as others have already stated. Take the engine off and check the firewall, examine all the glue joints and pull the covering from the damaged area and inspect and repair. Do find a local club in the area and get some instruction. It save you some frustration and some $. Spend $100 dollars and go get the Real Flight G5 basic simulator. It's save you even more money as you spend hours practicing on the computer. My helicopter skills have slipped from not flying them for many years and the simulator probably saved me a few hundred dollars in parts replacements.
