I am using the bisson pitts muffler. I was having back preasure problems. At about half tank the engine would lean out and die. I tried everything short of adding a pump to it. I ended up just crimping one of the stacks partially closed. It solveds everything and added a little power.
I also have a viper, had a super sportster and have a cosmic wind minow. I would say that none of thses planes are as challenging to land as the revolver. I have no problems getting it to land, just getting it to slow down.
