Dave, my tunnel also gets hot. I have to place a folded up towel between my right leg (bare) and the tunnel during flight. I've checked the firewall for leakage but haven't found anything as yet. I've got about 35 hrs on mine to date and it isn't cooling down with usage. I will be interested if others have the same or have found a solution. Steve
but not hot. Once the carpet kit is in and the flap boot was on it isn't really noticeable. Remember, all the cooling air from the engine is flowing right under the center section of the fuselage.
