No holes in the cowl front. The motor seems plenty exposed so mainly I'm doing this to get several flights in a row as I am out solo. Seems to me it is best to let the motor cool between flights but this is just my logic. Like IC engines after a flight, the electrics get pretty hot too.
Seems to cut down my wait to get back up in the air is all I am trying to show. 5 flights then home for other things.
