mark-
i have currently been running 19 turn class with my EVO III, due to the huge popularity of this class at my home track. my first race with the car i TQed the class by five seconds over other local fast guys with a 19t that i bought out of the case that day.
i have not run a modified motor through the car yet but im sure that it will nothing short of excellent.
as far as setting the car up for foams... i would just take the set-up that you are currently running on your 414m and get as close to it as you can on the EVO III. at the recent 2003 Puyallup Hobby Expo race here in Washington where i live, dan garber and myself where running almost the same set-up on both of our cars.(he was running the EVO III, and i was running the 414mII) the only things that were different in our set-ups were the things that were specific to the paticular chassis.
both cars were dialed, dan won the 19turn class, and i finished 7th in the open mod a-main.
happy racing.
