RE: SMOKE MUFFLER CONVERSION HELP
Hey Roger, long time no talk to! I have completely gone through the plane a-z, made a few changes and updates, and all is well. It has yet to fly after the updates, but that is only because the weather hasn't been friendly to me. I'll definitely keep you posted when I get the chance. I'll have to crash one of your camping trips too and get some flying in.
Anyway...about the smoke nipple...I've recently been using the std Great Planes\DuBro 'pressure tap' I believe they are called, and they work fine. I believe the size is 8/32 from memory. I just know for best results, tapping it into the mounting flange, pointing slightly away from the cylinder has worked well. At least this is what has been working well for me.
