Hello
The diffs that I intend to use are similar to the diffs of the photos, I saw these pictures on the net and you can get an idea of their size,The diffs of the flux are not meant to take on so much weight and on this car(27lbs) I do not believe that the flux diffs could last to long!
About the weight distribution I will try to move forward the lipos 3 inches and the motores 2 inches which is the maximum that can go.
