I have run the 1112 in a light 1/10 car no problems. Gotta gear it right, but it is fast. Used that holmes hobbies plate to bolt it up, you have to have 2.5m countersunk screws too.
How light? My Rustler is around 3-4 pounds and a CC CM36 motor powers it perfectly.
All I ever wanted was an honest weeks pay for an honest days work.
