I didn't get to fly today, as I had to do chores around the home. But I managed to get a little time to fabricate a quickie muffler baffle insert for the SV 17cc engine. As you can see from the other pics, they made a nice stainless steel muffler, but it does little to nothing to quiet the engine down any. So I made a simple baffle insert to stick into the exhaust outlet to help quiet the engine more. I'll find out how well it works when i test run the engine again using it.
I still have room to drill out the holes more if needed should the insert wind up being too restrictive and reducing the power too much. I can also chop a little off the bottom if needed too.
