Tonight I used RTV to secure the two emag blast tubes. These tubes direct air from the engine compartment onto the magnetos, helping cooling the magnetos during engine operation. I’m contemplating adding a blast tube to the alternator, but I’m concerned about moisture being blasted into the voltage regulator on the back of the alternator. This would be a problem when flying through clouds for example. The alternator is up front, but the emags are at the back of the engine. The emag blast tubes are less susceptible to moisture because of their location, so I’m not worried about them.
