I've only seen two robots with fans and both were pointed horizontal, so they add thrust but not traction. If I remember right, one of the updates had a clause outlawing "mass manipulation" to gain a traction advantage. I guess it is up to the inspector to judge whether a fan is mass manipulation.

On a separate note, why the heck to they have this rule in the first place? The possibility of increasing traction got our entire team talking physics forced everyone to come up with creative designs. Why limit creativity??
