Fan question, do you run the fan to where it’s blowing on the motor or pulling heat away from the motor ? Seems like a dumb question, I know , some cars I have the fan pushing and on some I have it pulling . What’s the best direction of flow ?

I have it pushing. I think that unless some sort of duct is used the fan pulling the air is somewhat useless but that’s just my opinion.

Always pushing in my RC cars.
