The 55ax is an awesome motor and coupled with a TH .46 muffler it will turn an APC 13x4 at 13,000rpm on 15% with instant throttle response.
What is a TH muffler and where do I get one? I hear the tower muffler is good also but its sold out until Jun or July I think. I haven't been into planes for a couple years so I'm trying to learn the good set ups again.
