I have just made 2 angel food cakes in as many weeks and both times, using different recipes, the rise was high, texture airy and both were perfectly baked. Make sure you do NOT overbeat the eggs, just firm yet glossy looking and be very careful when (hand) folding in the flour mix..do NOT over...
My wall oven measures 25.5 inches wide by 15.5 inches tall, with both ovens measuring the same. It is a Thermador but it was installed 15 years ago! Not a moment's problem/repair... ever! Obviously it only handles half tray pans. BUT I get 6 in at a time.
