The lack of armament would have made them generally a bit more slippery than their armed equivalents, and because of their small number, they would have been given special care in a number of aspects, from ensuring as near perfect maintenance as possible, to ensuring the pilots could navigate (lots of single pilot aircraft from all sides lost in WW2 because they got lost!).
