Jack211...With that Saito 100 you need a lot of room for the air to get out of the cowl. I basically cut the entire bottom out of the cowl and a great big hole up in the front to get the air in and out. Open that cowl wayyyyyy up. If you get enough airflow you won't overheat.
Also, you need a different prop. I used a 16x4W, some would rather use a 15x6 either is an excellent choice but not a 14" and not an 8 pitch. That will help with the aerobatics. You'll find the UCD will hover easier than the Twist and KE better and when you get used to it I think you find it's more fun to fly. 30% nitro will really liven the Saito up too.
Welcome to the thread and have a great time here...and of course, at the field.
THanks
