I presently fly an RV-4 based in Las Vegas, NV and was asked by Dave Edwards to evaluate his new design for a heat muff. This will be the second year that I have flown with his design and have to say that it does outperform my previous heat muff by a considerable margin. Granted it is not that cold in Las Vegas, but I recorded readings at 12,500 over the Sierra Nevada mountains of OAT of 15F while the cockpit temperature was a comfortable 65-70 degrees. The only heat outlet in my plane is on the floor in front of the back seat passenger. The heat from this single outlet was sufficient to heat the front seat as noted.
Removing the muff for Condition inspection involves removal of only two hose clamps around the muff body. For those of you that are looking at your heat needs, this is a simple, yet efficient muff for installation.
This heat muff is available through Aircraft Spruce (item pictured) and others as the Turbo Heat Cabin Heat Muff.
