Hey TryHard
with cutting the motor mount why is it that only cut the center out? why not cut it all the way to the edge making it clean (so it would look like the mount from the 416x).
id think by keeping the little extruded parts on the mounts, you would be actually limiting the total amount of flex that is possible. Thus you may not get a "true" representation of its handling effects.
Just my thoughts on the subject.
