RE: Zenoah 62 broken exhaust mount. Help please.
"The cylinder is cast aluminum. The muffler , and muflers bolts are steel. If the screws came loose in flight it MAY break the cylinder and ruin the engine. Other than that it is a great engine. Is that fair? "
jc, maybe not fair but all the engines are like that. That's why it's important to check your muffler screws before you start flying each day or when you get home after a day of flying. By the way, most, if not all, the engines use metric hardware. Make sure you are using a metric screw. Dan.
