Tram,

One problem with the 160 is where to put the muffler. The shape of this cowl does not lend it'self to a stock or pitts muffler without cutting. The best enclosed setup would be a ZDZ 40 header flange (which fits the 160) from Krumsfield, stainless pipe and a homemade muffler. The 160 may barely fit mounted 10 degrees below horizontal with a 3/8" spacer behind the prop, It is really close.

I think you would be happy with a Saito 150 or 180 on 10% nitro. The Enya works well also but needs some TLC to keep the plane clean and quiet. Once I figure out how to download fron my camera to the computer I'll post some photos of my installation.
