My 8.2 pound (dry) Model Tech Joss Stik w/ mid wing mod, flew straight up and outa sight with a cowled/inverted ST S90K/Magic Muffler using one of the older (not blunt edged) Zinger 14~8s. Ran it on 0% to 5% fuel. I wanted to make the plane fly at a constant speed and it flew at around 80mph in all (level, up, down) directions.
Have all the parts to build another one some day.

Is the Magic Muffler similar to the Macs muffler? Is there a significant power increase compared to the stock muffler?
