So my friend has his losi mini rally. He bought the same motor thats in the associated 14b/t and it doesnt get nearly as hot as they do in the associated cars. I'm really not sure why as the mini rally is way heavier then my 14b. Yes he has a fan on his but he runs 3s and he also has run without a fan. It gets hot without a fan but id expect it to get hotter because in my 14b it gets hot just on 2s. And you may say, well airflow is a huge thing! But his is so overpowered i just cant imagine airflow being so good that it keeps it cool. Buut I could be wrong
