I'm not familiar with either muffler or header since I left glow powered planes a few years ago. This will be one of two forays back into glow. If either type will attach to the exhaust outlet of the engine and point generally down, it should work. Tom may have more info on the muffler types than I do.

Could you post a pic or two in this thread for me to look at? That would help some.

This particular plane will have some differences from the production kits. Production planes will have the engine mounting box moved aft a little to make it easier to get the proper firewall to spinner back plate distance.

Try expo percentages of 75% on elevator, 65-70% on ailerons, and 60% on rudder at high rates.
