Ed, I have cut alot of .080 & .125 5052 aluminum with my dynatorch. What thickness are you interested in cutting? Cutting larger shapes works great however warpage can be a problem if you are doing alot of cuts in a small area on the material. I recently did a pattern on a 24" x 24" sheet of 3/16. It was basicly the shape of an (H) 13" high, 7" wide with a circular center (for mounting a fan). After cutting the center circle 1st I started on the perimeter and the thermal expansion caused the material to move an 1/8" during the cut which made the legs of the (H) difference widths. When possible you can pause the torch between cuts to allow for cooling. A spray water bottle helps also. I use a Hypertherm 1250 and fine cut tips. I will have to retreive the settings for you later when I go to the shop. I usually only do 1 part at a time when I cut aluminum and the part I cut is worth several hundred dollars when I place it on the table so there is no room for mistakes.
