With a power plant in the works, I started pondering the mufflers. After looking at the "mufflers" that come with the 111, I can see why people have taken to calling the exhaust diverters. While the sound rules at my field are reasonably easy to meet, I prefer a quieter plane, so I started pondering a canister setup. I've got power to spare for the plane, so any loss of power won't be a big deal, but I still wanted to put the biggest canisters in I could. Unfortunately, the original Lanier kit was produced well before canisters were the norm. After measuring and pondering a bit, I picked up a pair of DLE-55/111 cannisters from TBM.

Based on the measurements, they would be a tight fit, and test fitting them proved that. When they technically would fit with the stock setup under the radio bay floor, it would allow for very little air flow and generally be too tight all around. Plus, the mounts would actually protrude up into the radio bay. So, I made the decision to do some re-engineering. I am moving the floor of the radio bay up about 5/8" and rebuilding the landing gear mounts and the undercarriage back to the back of the radio bay. I cut out the floor and spent some time making lots of dust with the dremmel to get everything smoothed out and cleaned up.
