I have a fairly new RV14 (1 yr old - 90 hrs TT) that I purchased a few months ago. First long trip since the purchase and first night flight at altitude where I noticed a hot spot, actually feels like hot air blowing into the cabin above the pilots left rudder pedal. Not being the builder of the aircraft and new to RV’s, I am curious if there are common issues of hot air into the cabin and recommended fixes. I just completed the flight late last night and have not had to a chance to investigate. This along with a fair amount of heat from the area in the cabin along and above the exhaust needs to to be addressed or investigated as well. Any thoughts?
