Just a few thoughts:
Use the 1033. My 027 layout had one, and a 2055 PW small Hudson. It almost never "flew off the track", and when it did, I learned to control the throttle better. I was 7 years old. Learning is part of it. It quit flying (and the class lights on the smokebox front survived).
Some have added a screw/post stop to the throttle-sweep area of the transformer to physically limit the handle travel.
